86-616: It works collaboratively with Health Canada, with the federal agency represented as an ex-oficio member on PAAB's board of directors. PAAB originated in 1976 through a collaboration between the Pharmaceutical Manufacturing Association of Canada and the Canadian Medical Association . Within its first year, the organization had two staff members and had reviewed some 400 applications. As of July 1977, all advertisements printed in

172-507: A biblical framing in July 1918, using an interrogative from Exodus 16 in ancient Hebrew : "One thing is for certain—the doctors are at present flabbergasted; and we suggest that rather than calling the disease influenza they should for the present until they have it in hand, say Man hu —'What is it?'" Outbreaks of influenza-like illness were documented in 1916–17 at British military hospitals in Étaples , France , and just across

258-472: A "technical" pandemic that principally affected those 26 years of age and younger. While some natural explanations, such as the virus remaining in some frozen state for 20 years, have been proposed to explain this unprecedented phenomenon, the nature of influenza itself has been cited in favor of human involvement of some kind, such as an accidental leak from a lab where the old virus had been preserved for research purposes. Following this miniature pandemic,

344-540: A federal election happening that year, revealed its Demand a Plan campaign. Demand a Plan is a public campaign spearheaded by the CMA with the aim of having all levels of government work together to develop a comprehensive national seniors strategy. Over 74,000 people have signed up in support of the campaign. The Standing Committee on Human Resources, Skills and Social Development and the Status of Persons with Disabilities, in

430-786: A late peak between January–April 1920. Mexico experienced a fourth wave between February and March. In South America, Peru experienced "asynchronous recrudescent waves" throughout the year. A severe third wave hit Lima , the capital city, between January and March, resulting in an all-cause excess mortality rate approximately four times greater than that of the 1918–1919 wave. Ica similarly experienced another severe pandemic wave in 1920, between July and October. A fourth wave also occurred in Brazil, in February. Korea and Taiwan , both colonies of Japan at this time, also experienced pronounced outbreaks in late 1919 and early 1920. By mid-1920,

516-819: A major outbreak of the illness spread among people who had attended the parade. From Europe, the second wave swept through Russia in a southwest–northeast diagonal front, as well as being brought to Arkhangelsk by the North Russia intervention , and then spread throughout Asia following the Russian Civil War and the Trans-Siberian railway , reaching Iran (where it spread through the holy city of Mashhad ), and then later India in September, as well as China and Japan in October. The celebrations of

602-651: A major training ground for troops of the American Expeditionary Forces , to other U.S. Army camps and Europe, becoming an epidemic in the Midwest , East Coast , and French ports by April 1918, and reaching the Western Front by the middle of the month. It then quickly spread to the rest of France, Great Britain, Italy, and Spain and in May reached Wrocław and Odessa . After the signing of

688-602: A national body. The CMA's first president was Sir Charles Tupper , the Nova Scotia Premier who led that province into confederation and later became Prime Minister of Canada . The foundation of the CMA was strongly rooted in its Scottish origins as the first three presidents of the CMA graduated from the Edinburgh Medical School . Among the CMA's founding principles in 1867 was to "improve public health and prevent disease and disability,"

774-430: A patient's perspective to the CMA's work. A health summit attended by a wide spectrum of medical and health professionals as well as patient representatives is held annually to disseminate new research, information and innovations, and to debate issues facing the medical community and users of medical services. A public annual general meeting is held to review financial statements and other CMA business matters. As well,

Othering derived from geopolitical borders and social boundaries. In Poland it was the ' Bolshevik disease', while the Bolsheviks referred to it as the ' Kirghiz disease'. Some Africans called it a 'white man's sickness', but in South Africa , white men also used

This outbreak was also commonly known as the 'great influenza epidemic', after the 'great war', a common name for World War I before World War II . French military doctors originally called it 'disease 11' ( maladie onze ). German doctors downplayed

1032-460: A public information campaign before the end of the summer, and Britain began preparations in the autumn with the manufacture of vaccine. In Japan, the flu broke out again in December and spread rapidly throughout the country, a fact attributed at the time to the coming of cold weather. Pandemic-related measures were renewed to check the spread of the outbreak, and health authorities recommended

1118-450: A purpose which remains today. The CMA Code of Ethics has been around in one form or another since 1868. As recently as 2015 this document was considered by the CMA to be "arguably the most important document produced by the CMA. It has a long and distinguished history of providing ethical guidance to Canada’s physicians. Focus areas include decision-making, consent, privacy, confidentiality, research and physician responsibilities. The code

1204-438: A regulatory framework to protect children and youth. Advances in technology could bridge the physical divide between doctors and patients, thereby reducing wait times and health care costs. Technologies such as virtual reality, artificial intelligence and robotics hold significant promise for patients and physicians, particularly for a country like Canada with its large land base and numerous remote communities. In early 2019,

1290-541: A report in March 2018, adopted many of the recommendations made the previous year by the CMA on ways to better serve seniors with improvements to housing, income security and quality of life. After the success of Demand a Plan campaign, the CMA launched a second public mobilization platform called CMA Health Advocates. This platform is designed to engage Canadians on improving health care, and to connect with local politicians to share their health and health care stories. During

1376-667: A result of the lifting of the ban on public gatherings. Pandemic interventions, such as bans on public gatherings and the closing of schools, were reimposed in many places in an attempt to suppress the spread. There was "a very sudden and very marked rise in general death rate" in most cities in January 1919; nearly all experienced "some degree of recrudescence" of the flu in January and February. Significant outbreaks occurred in cities including Los Angeles , New York City, Memphis , Nashville , San Francisco , and St. Louis . By 21 February, with some local variation, influenza activity

1462-617: A strict maritime quarantine had shielded the country through the latter part of 1918. It assumed epidemic proportions first in Melbourne , peaking in mid-February. The flu soon appeared in neighboring New South Wales and South Australia and then spread across the country throughout the year. New South Wales experienced its first wave of infection between mid-March and late May, while a second, more severe wave occurred in Victoria between April and June. Land quarantine measures hindered

1548-461: A unanimous decision, struck down the Criminal Code 's absolute prohibition on physician-assisted death. As a result, the CMA developed foundational principles for medical aid in dying to guide discussions with its members and with the federal government on ensuring patient dignity and upholding the rights of both patients and physicians. Consultations included submissions and presentations to

1634-661: Is a national, voluntary association of physicians and medical learners that advocates on national health matters . Its primary mandate is to drive positive change in health care by advocating on key health issues facing doctors and their patients. CMA publicates the Canadian Medical Association Journal (often abbreviated as CMAJ ) which is a peer-reviewed medical journal that offers original clinical research, commentaries, analyses and reviews of clinical topics, health news, and clinical-practice updates. The CMA has over 75,000 members and

1720-633: Is fundamentally the same condition as the influenza of this present pandemic." This " purulent bronchitis " is not yet linked to the same A/H1N1 virus, but it may be a precursor. In 1918, ' epidemic influenza ' ( Italian : influenza , influence), also known at the time as 'the grip' ( French : la grippe , grasp), appeared in Kansas in the U.S. during late spring, and early reports from Spain began appearing on 21 May. Reports from both places called it 'three-day fever' ( fiebre de los tres días ). Many alternative names are exonyms in

1806-715: Is governed by a board of 12 members, including representation from industry associations Innovative Medicines Canada , BIOTECanada , Association of Medical Advertising Agencies, Canadian Association of Medical Publisher and Consumer Health Products Canada. Notable former members of the board include Susan Eng , former Chair of the Canadian Association of Retired Persons . Clients of PAAB include pharmaceutical companies and advertising agencies working on behalf of pharmaceutical interests.

1892-503: Is in town," making 'the Spanish lady' another common name. The outbreak did not originate in Spain (see below ), but reporting did, due to wartime censorship in belligerent nations. Spain was a neutral country unconcerned with appearances of combat readiness , and without a wartime propaganda machine to prop up morale ; so its newspapers freely reported epidemic effects, including King Alfonso XIII 's illness, making Spain

1978-610: Is the largest association of medical doctors in Canada . Its membership includes physicians and medical learners. The CMA represents Canadian physicians from medical school through to residency, medical practice and retirement. The CMA's origins may rest with Dr. Joseph Painchaud and other Quebec physicians who in 1844 hoped to find ways to help physicians and, after their deaths, their widows and orphans. There were false starts in attempts to form an association, but soon after confederation, practicing physicians were successful in developing

2064-458: Is updated every 5-6 years and has a major revision approximately every 20 years. Changes must be approved by CMA General Council." The fledgling association faced a lot of growing pains in its first 25 years as meeting attendance was small. There was even a notice of motion in 1894 to disband it. The Montreal Medical Journal was taken over in 1911 to become the CMA Journal . In 1921,

2150-506: The 1977 Russian flu and the 2009 Swine flu pandemics. This pandemic was known by many different names—some old, some new—depending on place, time, and context. The etymology of alternative names historicises the scourge and its effects on people who would only learn years later that invisible viruses caused influenza . The lack of scientific answers led the Sierra Leone Weekly News ( Freetown ) to suggest

2236-516: The Armistice of 11 November 1918 also caused outbreaks in Lima and Nairobi , but by December the wave was mostly over. The second wave of the 1918 pandemic was much more deadly than the first. The first wave had resembled typical flu epidemics; those most at risk were the sick and elderly, while younger, healthier people recovered easily. October 1918 was the month with the highest fatality rate of

2322-645: The Boston Navy Yard and Camp Devens (later renamed Fort Devens ), about 30 miles west of Boston, other U.S. military sites were soon afflicted, as were troops being transported to Europe. Helped by troop movements, it spread over the next two months to all of North America, and then to Central and South America , also reaching Brazil and the Caribbean on ships. In July 1918, the Ottoman Empire saw its first cases in some soldiers. From Freetown,

2408-768: The Canadian Medical Association Journal carried the PAAB seal of approval following an examination of their quality and accuracy. In 2004, PAAB's Patient Material Code was revised to include materials provided to patients by healthcare providers as well as adding regulations to standardize advertising over the internet. As of 2015, PAAB reported completing over 7,000 "first reviews" annually. Advertising materials for all health products in Canada that are intended for healthcare professionals are submitted for review and pre-clearance by PAAB, who prescribes

2494-553: The English Channel at Aldershot , England . Clinical indications in common with the 1918 pandemic included rapid symptom progression to a "dusky" heliotrope cyanosis of the face. This characteristic blue-violet cyanosis in expiring patients led to the name 'purple death'. The Aldershot physicians later wrote in The Lancet , "the influenza pneumococcal purulent bronchitis we and others described in 1916 and 1917

2580-956: The Great Influenza epidemic or by the common misnomer Spanish flu , was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus . The earliest documented case was March 1918 in the state of Kansas in the United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected in four successive waves. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it one of

2666-602: The Treaty of Brest-Litovsk (March 1918), Germany started releasing Russian prisoners of war, who then brought the disease to their country. It reached North Africa, India, and Japan in May, and soon after had likely gone around the world as there had been recorded cases in Southeast Asia in April. In June an outbreak was reported in China . After reaching Australia in July, the wave started to recede. The first wave of

Japan blamed sumo wrestlers for bringing the disease home from a match in Taiwan by calling it 'sumo flu' ( Sumo Kaze ), even though three top wrestlers died there. World Health Organization 'best practices' first published in 2015 now aim to prevent social stigma by no longer associating culturally significant names with new diseases, listing "Spanish flu" under "examples to be avoided". Many authors now eschew calling this

2838-469: The first of these post-1918 pandemics , in 1957, the virus was totally displaced by the novel H2N2 , the reassortant product of the human H1N1 and an avian influenza virus, which thereafter became the active influenza A virus in humans. In 1977, an influenza virus bearing a very close resemblance to the seasonal H1N1, which had not been seen since the 1950s, appeared in Russia and subsequently initiated

2924-528: The 'Spanish grip'. And wherefore Spanish? …this epidemic was not born in Spain, and this should be recorded as a historic vindication." But before this letter could be published, The Serbian Newspaper ( Corfu ) said, "Various countries have been assigning the origin of this imposing guest to each other for quite some time, and at one point in time they agreed to assign its origin to the kind and neutral Spain…" French press initially used 'American flu', but adopted 'Spanish flu' in lieu of antagonizing an ally. In

3010-698: The 2019 federal election, the CMA Health Advocates platform will be tracked each party's platform promises. Choosing Wisely Canada was launched by Dr. Wendy Levinson in 2014 in partnership with the CMA to help physicians and patients reduce unnecessary tests, treatments and procedures, and ensure high-quality care. Central to the campaign are lists developed by more than 45 specialty societies to encourage critical thinking that will avoid unnecessary and potentially harmful tests and procedures. The federal government's Advisory Panel on Healthcare Innovation urged governments in all jurisdictions to support

3096-602: The CMA launched a Virtual Care Task Force alongside the Royal College of Physicians and Surgeons of Canada and the College of Family Physicians of Canada to explore the barriers affecting the effective implementation of virtual care in the Canadian health system. Recommendations are expected in early 2020. Physician health and wellness has become a key priority of the CMA. In 2018, a national snapshot report released by

3182-479: The CMA often advocates on key health issues that matter to Canadians and its members. In developing its positions, it seeks input through town hall meetings, surveys its members and reviews relevant scientific research. It also seeks input from provincial and territorial medical associations and from its more than 60 affiliate, associate and stakeholder organizations. In 2015, the Supreme Court of Canada , in

3268-504: The CMA re-organized with the appointment of its first permanent general-secretary, Dr. T.C. Routley. The association also became more financially stable by raising funds with a bond issue. Over the years, the CMA and its physician members have advocated on behalf of patients and educated the public to limit the effects of outbreaks, such as the 1918 Spanish flu , SARS in 2002 and the H1N1 influenza pandemic in 2009–2010. In an effort to raise awareness and research treatment of cancer ,

3354-405: The CMA showed that while physicians report high resiliency, they also experience high levels of burnout and depression, particularly residents and women. To help respond to this growing issue, the CMA has implemented a physician health and wellness department led by Dr. Caroline Gérin-Lajoie. An environmental scan is underway to further identify key issues and possible solutions. In 2009, the CMA

3440-441: The Spanish flu, instead using variations of '1918–19/20 flu/influenza pandemic'. Some language endonyms did not name specific regions or groups of people. Examples specific to this pandemic include: Northern Ndebele : 'Malibuzwe' (let enquiries be made concerning it), Swahili : 'Ugonjo huo kichwa na kukohoa na kiuno' (the disease of head and coughing and spine), Yao : 'chipindupindu' (disease from seeking to make

3526-503: The United States as early as late November 1918, with the Public Health Service issuing its first report of a "recrudescence of the disease" being felt in "widely scattered localities" in early December. This resurgent activity varied across the country, however, possibly on account of differing restrictions. Michigan , for example, experienced a swift resurgence of influenza that reached its peak in December, possibly as

3612-421: The United States subsided as swiftly as it had appeared, reaching a peak in early February. "An epidemic of considerable proportions marked the early months of 1920", the U.S. Mortality Statistics would later note; according to data at this time, the epidemic resulted in one third as many deaths as the 1918–1919 experience. New York City alone reported 6,374 deaths between December 1919 and April 1920, almost twice

3698-544: The apparent locus of the epidemic. The censorship was so effective that Spain's health officials were unaware its neighboring countries were similarly affected. In an October 1918 "Madrid Letter" to the Journal of the American Medical Association , a Spanish official protested, "we were surprised to learn that the disease was making ravages in other countries, and that people there were calling it

3784-547: The association holds an annual General Council meeting of its members to discuss policy matters. The CMA's subsidiary company, Joule, was created on Sept. 1, 2014. It delivers continuing education to doctors, resources for accessing medical information online, clinical information resources and summaries of the latest clinical evidence. CMAJ is published by Joule. Joule's grant program funds CMA member innovations that potentially may assist in healthcare advancements. Spanish flu The 1918–1920 flu pandemic , also known as

3870-409: The claim that young adults had a high mortality during the pandemic has been contested. Malnourishment, overcrowded medical camps and hospitals, and poor hygiene , exacerbated by the war, promoted bacterial superinfection , killing most of the victims after a typically prolonged death bed. The 1918 Spanish flu was the first of three flu pandemics caused by H1N1 influenza A virus ; the others being

The CMA identified potential risks of cannabis use and has addressed them in submissions to House of Commons standing committees. Following the introduction of the Cannabis Act , the association provided guidance to the federal government on

4042-560: The country were soon to follow. Certain pandemic restrictions, such as the closing of schools and theaters and the staggering of business hours to avoid congestion, were reimposed in cities like Chicago, Memphis, and New York City. As they had during the epidemic in fall 1918, schools in New York City remained open, while those in Memphis were shuttered as part of more general restrictions on public gatherings. The fourth wave in

4128-399: The deadliest pandemics in history . The pandemic broke out near the end of World War I , when wartime censors in the belligerent countries suppressed bad news to maintain morale , but newspapers freely reported the outbreak in neutral Spain , creating a false impression of Spain as the epicenter and leading to the "Spanish flu" misnomer. Limited historical epidemiological data make

4214-474: The disease was regarded as being milder than it had been the year before, albeit more infectious. Despite its rapid peak at the beginning of the year, the outbreak persisted throughout the winter, before subsiding in the spring. In the United States, there were "almost continuously isolated or solitary cases" of flu throughout the spring and summer months of 1919. An increase in scattered cases became apparent as early as September, but Chicago experienced one of

4300-716: The disease was soon misnamed 'Spanish influenza'. In a 2 June 1918 The Times of London dispatch titled, "The Spanish Epidemic," a correspondent in Madrid reported over 100,000 victims of, "The unknown disease…clearly of a gripal character," without referring to "Spanish influenza" directly. Three weeks later The Times reported that, "Everybody thinks of it as the 'Spanish' influenza to-day." Three days after that an advertisement appeared in The Times for Formamint tablets to prevent "Spanish influenza". When it reached Moscow, Pravda announced, " Ispánka (the Spanish lady)

4386-449: The disease, a novel one in 1918, assumed a more familiar nature, coming to represent at least one form of the "seasonal flu". The virus, H1N1, remained endemic, occasionally causing more severe or otherwise notable outbreaks as it gradually evolved over the years. The period since its initial appearance in 1918 has been termed a "pandemic era", in which all flu pandemics since its emergence have been caused by its own descendants. Following

4472-467: The editors of the U.S. Public Health Service 's academic journal Public Health Reports . Within days of the 4 March first case at Camp Funston, 522 men at the camp had reported sick. By 11 March 1918, the virus had reached Queens , New York. Failure to take preventive measures in March/April was later criticized. As the U.S. had entered World War I, the disease quickly spread from Camp Funston,

The CMA continues to work with government on matters such as medically assisted dying for children, as well as for those with mental illnesses but no other conditions. In 2015 the CMA began its first major public mobilization effort, and in conjunction with

4644-461: The first major outbreaks of the flu beginning in the middle of January. The Public Health Service announced it would take steps to "localize the epidemic", but the disease was already causing a simultaneous outbreak in Kansas City and quickly spread outward from the center of the country in no clear direction. A few days after its first announcement, PHS issued another assuring that the disease

4730-539: The first quarter of 1918. However, the first wave caused a significant disruption in the military operations of World War I , with three-quarters of French troops, half the British forces, and over 900,000 German soldiers sick. The second wave began in the second half of August 1918, probably spreading to Boston , Massachusetts and Freetown , Sierra Leone , by ships from Brest , where it had likely arrived with American troops or French recruits for naval training. From

4816-459: The first time just in October 1918, experienced a severe second wave, with mortality peaking in August 1919. Montevideo similarly experienced a second outbreak between July and September. The third wave particularly affected Spain, Serbia , Mexico and Great Britain, resulting in hundreds of thousands of deaths. It was in general less severe than the second wave but still much more deadly than

4902-415: The flu lasted from the first quarter of 1918 and was relatively mild. Mortality rates were not appreciably above normal; in the United States ~75,000 flu-related deaths were reported in the first six months of 1918, compared to ~63,000 deaths during the same time period in 1915. In Madrid, Spain, fewer than 1,000 people died from influenza between May and June 1918. There were no reported quarantines during

4988-555: The form of a true "third wave". Hong Kong experienced another outbreak in June, as did South Africa during its fall and winter months in the Southern Hemisphere . New Zealand also experienced some cases in May. Parts of South America experienced a resurgence of pandemic activity throughout 1919. A third wave hit Brazil between January and June. Between July 1919 and February 1920, Chile , which had been affected for

5074-409: The guidelines for direct marketing to this group. Educational materials and other messaging directed towards consumers on prescription drugs and the medical conditions they treat are reviewed by PAAB and Advertising Standards Canada to ensure compliance with regulatory requirements. While these reviews are not mandatory, PAAB is obligated to forward all safety-related complaints to Health Canada. PAAB

5160-522: The initial first wave. In the Northern Hemisphere, fears of a "recurrence" of the flu grew as fall approached. Experts cited the history of past flu epidemics, such as that of 1889–1890, to predict that such a recurrence a year later was not unlikely, though not all agreed. In September 1919, U.S. Surgeon General Rupert Blue said a return of the flu later in the year would "probably, but by no means certainly," occur. France had readied

5246-695: The initiative. The CMA continues to advocate that Canadians should have access to medically necessary pharmaceuticals that are safe, effective, available when and where needed and reasonably priced. The CMA is an active member of the Pan-Canadian Collaborative on Education for Improved Opioid Prescribing, which is chaired by the College of Family Physicians of Canada. The CMA's position is that opioids are important for managing pain, but prescribing them must be based on evidence and include careful assessment and monitoring. The CMA endorsed

5332-485: The last quarter of 1918 alone. Pandemic activity persisted, in general, into 1919 in many places. This persistence in activity is possibly attributable to climate, specifically in the Northern Hemisphere , where it was winter and thus the usual time for influenza activity. The pandemic nonetheless continued into 1919 largely independent of region and climate. Cases began to rise again in some parts of

5418-568: The most complex and ethically challenging issues facing Canadian physicians. The CMA supports its members in exercising their freedom of conscience - both for those who chose to provide or participate in physician assisted suicide and those who do not. The CMA also played a central role in the creation of the Registered Retirement Savings Plan in 1957 as a tool to provide its members financial security in retirement.

5504-425: The number of the first wave in spring 1918. Other U.S. cities including Detroit, Milwaukee, Kansas City, Minneapolis, and St. Louis were hit particularly hard, with death rates higher than all of 1918. The Territory of Hawaii experienced its peak of the pandemic in early 1920, recording 1,489 deaths from flu-related causes, compared with 615 in 1918 and 796 in 1919. Poland experienced a devastating outbreak during

The association provided most of the funds for the early years of the CCS based on interest generated from public donations made to a fund honoring King George V 's silver jubilee . Since the 1950s, the CMA has advised against tobacco use. It has fought against promotional tobacco marketing and for new laws that curbed smoking and other tobacco consumption among Canadians. The CMA played an important role in medical assistance in dying (MAID) legislation, calling it one of

5676-905: The pandemic continued to spread through West Africa along the coast, rivers, and the colonial railways, and from railheads to more remote communities, while South Africa received it in September on ships bringing back members of the South African Native Labour Corps returning from France. From there it spread around southern Africa and beyond the Zambezi , reaching Ethiopia in November. On 15 September, New York City saw its first fatality from influenza. The Philadelphia Liberty Loans Parade , held in Philadelphia , Pennsylvania , on 28 September 1918 to promote government bonds for World War I, resulted in 12,000 deaths after

5762-406: The pandemic was largely considered to be "over" by the public as well as governments. Though parts of Chile experienced a third, milder wave between November 1920 and March 1921, the flu seemed to be mostly absent through the winter of 1920–1921. In the United States, for example, deaths from pneumonia and influenza were "very much lower than for many years". Seasonal Influenza after the end of

5848-484: The pandemic's geographic origin indeterminate, with competing hypotheses on the initial spread. Most influenza outbreaks disproportionately kill the young and old, with a higher survival rate in-between, but this pandemic had unusually high mortality for young adults. Scientists offer several explanations for the high mortality, including a six-year climate anomaly affecting migration of disease vectors with increased likelihood of spread through bodies of water. However,

5934-499: The pandemic, began to be reported again from many places in 1921. Influenza continued to be felt in Chile, where a post pandemic fourth wave affected seven of its 24 provinces between June and December 1921. The winter of 1921–1922 was the first major reappearance of seasonal influenza in the Northern Hemisphere after the pandemic ended, in many parts its most significant occurrence since the main pandemic in late 1918. Northwestern Europe

6020-598: The practice of making new infectious diseases seem foreign. This pattern was observed even before the 1889–1890 pandemic , also known as the 'Russian flu', when the Russians already called epidemic influenza the 'Chinese catarrh', the Germans called it the 'Russian pest', while the Italians in turn called it the 'German disease'. These epithets were re-used in the 1918 pandemic, along with new ones. Outside Spain,

6106-516: The reemerged H1N1 became endemic once again but did not displace the other active influenza A virus, H3N2 (which itself had displaced H2N2 through a pandemic in 1968 ). For the first time, two influenza A viruses were observed in cocirculation. This state of affairs has persisted even after 2009, when a novel H1N1 virus emerged, sparked a pandemic , and thereafter took the place of the seasonal H1N1 to circulate alongside H3N2. Despite its name, historical and epidemiological data cannot identify

6192-461: The severity by calling it 'pseudo influenza' (Latin: pseudo , false), while in Africa, doctors tried to get patients to take it more seriously by calling it 'influenza vera' (Latin: vera , true). A children's song from the 1889–90 flu pandemic was shortened and adapted into a skipping-rope rhyme popular in 1918. It is a metaphor for the transmissibility of 'Influenza', where that name

6278-431: The spread of the disease, resulting in varied experiences of exposures and outbreaks among the various states. Queensland was not infected until late April; Western Australia avoided the disease until early June, and Tasmania remained free from it until mid-August. Out of the six states, Victoria and New South Wales experienced generally more extensive epidemics. Each experienced another significant wave of illness over

6364-534: The spring of 1918, British soldiers called it 'Flanders flu', while German soldiers used ' Flandern-Fieber ' (Flemish fever), both after a famous battlefield in Belgium where many soldiers on both sides fell ill. In Senegal it was named 'Brazilian flu', and in Brazil , 'German flu'. In Spain it was also known as the 'French flu' ( gripe francesa ), or the 'Naples Soldier' ( Soldado de Nápoles ), after

6450-418: The use of masks. The epidemic intensified in the latter part of December before swiftly peaking in January. Between October 1919 and 23 January 1920, 780,000 cases were reported across the country, with at least 20,000 deaths recorded by that date. This apparently reflected "a condition of severity three times greater than for the corresponding period of" 1918–1919, during Japan's first epidemic. Nonetheless,

6536-473: The whole pandemic. In the United States, ~292,000 deaths were reported between September–December 1918, compared to ~26,000 during the same time period in 1915. The Netherlands reported over 40,000 deaths from influenza and acute respiratory disease. Bombay reported ~15,000 deaths in a population of 1.1 million. The 1918 flu pandemic in India was especially deadly, with an estimated 12.5–20 million deaths in

6622-567: The winter months, with its capital Warsaw reaching a peak of 158 deaths in a single week, compared to the peak of 92 reached in December 1918; however, the 1920 epidemic passed in a matter of weeks, while the 1918–1919 wave had developed over the entire second half of 1918. By contrast, the outbreak in western Europe was considered "benign", with the age distribution of deaths beginning to take on that of seasonal flu . Five countries in Europe (Spain, Denmark, Finland, Germany and Switzerland) recorded

6708-507: The winter. The second epidemic in New South Wales was more severe than the first, while Victoria saw a third wave that was somewhat less extensive than its second, more akin to its first. The disease also reached other parts of the world for the first time in 1919, such as Madagascar , which saw its first cases in April; the outbreak had spread to practically all sections of the island by June. In other parts, influenza recurred in

6794-578: Was clipped to the apheresis 'Enza': I had a little bird, its name was Enza. I opened the window, and in-flu-enza. The pandemic is conventionally marked as having begun on 4 March 1918 with the recording of the case of Albert Gitchell, an army cook at Camp Funston in Kansas , United States, despite there having been cases before him. The disease had already been observed 200 miles (320 km) away in Haskell County as early as January 1918, prompting local doctor Loring Miner to warn

6880-415: Was affected by "a substantial recrudescent wave" of influenza between January and April 1919. Portugal experienced a resurgence in pandemic activity that lasted from March to September 1919, with the greatest impact being felt on the west coast and in the north of the country; all districts were affected between April and May specifically. Influenza entered Australia for the first time in January 1919 after

6966-504: Was criticized for partnering with Pfizer to launch a continuing medical education program. The size of the elected board of directors is transitioning to 19. The board includes physician, resident and student representatives. It is the executive authority of the CMA, meets four times a year and is responsible for policy direction. In 2018, the association launched the CMA Patient Voice, a group of 12 individuals that provide

7052-527: Was developed in 1969 to provide financial services to physicians and their families. It was sold in 2018 to Scotiabank, the sale including a 10-year collaboration agreement. In 2018, the CMA ended its membership in the World Medical Association (WMA) to protest the plagiarism found in the speech of the WMA's incoming president. As a national association of physicians and medical learners,

7138-582: Was not until later in the winter and into the spring that a clearer resurgence appeared in Europe. A significant third wave had developed in England and Wales by mid-February, peaking in early March, though it did not fully subside until May. France also experienced a significant wave that peaked in February, alongside the Netherlands. Norway , Finland , and Switzerland saw recrudescences of pandemic activity in March, and Sweden in April. Much of Spain

7224-533: Was particularly affected. All-cause mortality in the Netherlands approximately doubled in January 1922 alone. In Helsinki , a major epidemic (the fifth since 1918) prevailed between November and December 1921. The flu was also widespread in the United States, its prevalence in California reportedly greater in early March 1922 than at any point since the pandemic ended in 1920. In the years after 1920,

7310-414: Was reported to have been declining since mid-January in all parts of the country. Following this "first great epidemic period" that had commenced in October 1918, deaths from pneumonia and influenza were "somewhat below average" in the large cities of the United States between May 1919 and January 1920. Nonetheless, nearly 160,000 deaths were attributed to these causes in the first six months of 1919. It

7396-498: Was under the control of state health authorities and that an outbreak of epidemic proportions was not expected. It became apparent within days of the start of Chicago's explosive growth in cases that the flu was spreading in the city at an even faster rate than in winter 1919, though fewer were dying. Within a week, new cases in the city had surpassed its peak during the 1919 wave. Around the same time, New York City began to see its own sudden increase in cases, and other cities around
