83-546: Global Forest Watch originally began in 1997 as an initiative to establish a global forest monitoring network, convened by the World Resources Institute and partners. The initiative was rebooted in 2013 with data from the Center for Global Development derived from NASA 's MODIS sensor, with additional layers subsequently added from Google / UMD , Imazon , Terra-i, and NASA . The second iteration of GFW

166-725: A decreased level of consciousness . Bacterial and viral cases of pneumonia usually result in similar symptoms. Some causes are associated with classic, but non-specific, clinical characteristics. Pneumonia caused by Legionella may occur with abdominal pain, diarrhea , or confusion. Pneumonia caused by Streptococcus pneumoniae is associated with rusty colored sputum. Pneumonia caused by Klebsiella may have bloody sputum often described as "currant jelly". Bloody sputum (known as hemoptysis ) may also occur with tuberculosis , Gram-negative pneumonia, lung abscesses and more commonly acute bronchitis . Pneumonia caused by Mycoplasma pneumoniae may occur in association with swelling of

249-516: A leading cause of death in developing countries, and also among the very old, the very young, and the chronically ill. Pneumonia often shortens the period of suffering among those already close to death and has thus been called "the old man's friend". People with infectious pneumonia often have a productive cough , fever accompanied by shaking chills , shortness of breath , sharp or stabbing chest pain during deep breaths, and an increased rate of breathing . In elderly people, confusion may be

332-401: A stethoscope or increased respiratory rate. Grunting and nasal flaring may be other useful signs in children less than five years old. Lack of wheezing is an indicator of Mycoplasma pneumoniae in children with pneumonia, but as an indicator it is not accurate enough to decide whether or not macrolide treatment should be used. The presence of chest pain in children with pneumonia doubles

415-655: A "think and do" tank, and thus has multiple initiatives to implement their policy suggestions. These, initiatives attempt to give specific policy recommendations to organizations while creating a dialogue. In 2003, David Roodman created the Commitment to Development Index with Foreign Policy magazine and Mapping Worlds. The Commitment to Development Index (CDI) ranks and analyzes nations’ financial and political commitments to development every year. The index uses interactive graphs and analyzes how countries contribute to development in seven policy areas: aid (both quantity as

498-418: A chest radiograph is recommended. Findings do not always match the severity of disease and do not reliably separate between bacterial and viral infection. X-ray presentations of pneumonia may be classified as lobar pneumonia , bronchopneumonia , lobular pneumonia , and interstitial pneumonia . Bacterial, community-acquired pneumonia classically show lung consolidation of one lung segmental lobe , which

581-493: A cough of longer duration, and pulmonary emboli present with acute onset sharp chest pain and shortness of breath. Mild pneumonia should be differentiated from upper respiratory tract infection (URTI). Severe pneumonia should be differentiated from acute heart failure . Pulmonary infiltrates that resolved after giving mechanical ventilation should point to heart failure and atelectasis rather than pneumonia. For recurrent pneumonia, underlying lung cancer, metastasis , tuberculosis,

664-479: A cough or difficulty breathing and a rapid respiratory rate, chest indrawing, or a decreased level of consciousness. A rapid respiratory rate is defined as greater than 60 breaths per minute in children under 2 months old, greater than 50 breaths per minute in children 2 months to 1 year old, or greater than 40 breaths per minute in children 1 to 5 years old. In children, low oxygen levels and lower chest indrawing are more sensitive than hearing chest crackles with

747-415: A day or two before other signs. Examination of the chest may be normal, but it may show decreased expansion on the affected side. Harsh breath sounds from the larger airways that are transmitted through the inflamed lung are termed bronchial breathing and are heard on auscultation with a stethoscope. Crackles (rales) may be heard over the affected area during inspiration . Percussion may be dulled over

830-407: A development agenda that incorporates migration from low and middle-income to high-income countries, where wages for the same task can be up to ten times higher. However, they argue that the misperception that development is about places rather than people often leads policymakers as well as economists to ignore the large benefits to the migrants themselves. Rich countries' immigration policies are also

913-518: A factor in the Commitment to Development Index . CGD has advocated for temporary visas for Haitians to seasonally work in US agriculture and participated in an initiative to that end. In 2016, they issued a report on how policymakers can manage migration between the United States and Mexico to the benefit of both countries. CGD Senior Fellow Ranil Dissanayake publishes a weekly blog associated with

996-800: A foreign bodies, immunosuppression, and hypersensitivity should be suspected. Prevention includes vaccination , environmental measures, and appropriate treatment of other health problems. It is believed that, if appropriate preventive measures were instituted globally, mortality among children could be reduced by 400,000; and, if proper treatment were universally available, childhood deaths could be decreased by another 600,000. Vaccination prevents against certain bacterial and viral pneumonias both in children and adults. Influenza vaccines are modestly effective at preventing symptoms of influenza, The Centers for Disease Control and Prevention (CDC) recommends yearly influenza vaccination for every person 6 months and older. Immunizing health care workers decreases

1079-400: A higher dose of radiation, and cannot be done at bedside. Lung ultrasound may also be useful in helping to make the diagnosis. Ultrasound is radiation free and can be done at bedside. However, ultrasound requires specific skills to operate the machine and interpret the findings. It may be more accurate than chest X-ray. In people managed in the community, determining the causative agent

1162-462: A history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system . Vaccines to prevent certain types of pneumonia (such as those caused by Streptococcus pneumoniae bacteria, linked to influenza , or linked to COVID-19 ) are available. Other methods of prevention include hand washing to prevent infection, and not smoking. Treatment depends on the underlying cause. Pneumonia believed to be due to bacteria

1245-410: A new headquarters that includes a 170-seat state-of-the-art conference center, a 60-seat boardroom/ideas lab, and a multimedia studio. CGD conducts research within a range of topics that impact global poverty and people of the developing world. Topics include aid effectiveness , education, globalization and global health , as well as the impact of trade and migration on development. The center

1328-491: A report on the dangers of drug resistance in "The Race against Drug Resistance: When Medicines Fail", which the Global Health team launched on June 14, 2010. The center's Migration and Development Initiative aims to study the effects labor movement has not only on the receiving country, but also on the country of origin and the migrants themselves. CGD economists Michael Clemens and Lant Pritchett have advocated for

Other initiatives include Cash on Delivery Aid, Combating Drug Resistance, Development Impact Bonds, Europe Beyond Aid, the Latin America Initiative, Migration as a Tool for Disaster Recovery, Oil-to-Cash: Fighting the Resource Curse through Cash Transfers, Pakistan: US Development Strategy, Preemptive Contract Sanctions, Reforming Trade Preferences, Rethinking US Development Policy, The Future of

1494-416: A year that draw more than 7,000 participants. Events have featured speakers such as U.S. Secretary of State Hillary Clinton , President of Nigeria Goodluck Jonathan , economist Paul Romer , UK Secretary of State for International Development Andrew Mitchell , among many others. During Secretary Hillary Clinton ’s visit to CGD on January 6, 2010, she emphasized the importance of development and said it

1577-400: Is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli . Symptoms typically include some combination of productive or dry cough , chest pain , fever, and difficulty breathing . The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms . Identifying

1660-411: Is another rare cause due to lipids entering the lung. These lipids can either be inhaled or spread to the lungs from elsewhere in the body. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. It is a type of pneumonitis (lung inflammation). The normal flora of the upper airway give protection by competing with pathogens for nutrients. In

1743-996: Is associated with Chlamydia psittaci ; farm animals with Coxiella burnetti ; aspiration of stomach contents with anaerobic organisms; and cystic fibrosis with Pseudomonas aeruginosa and Staphylococcus aureus . Streptococcus pneumoniae is more common in the winter, and it should be suspected in persons aspirating a large number of anaerobic organisms. In adults, viruses account for about one third of pneumonia cases, and in children for about 15% of them. Commonly implicated agents include rhinoviruses , coronaviruses , influenza virus , respiratory syncytial virus (RSV), adenovirus , and parainfluenza . Herpes simplex virus rarely causes pneumonia, except in groups such as newborns, persons with cancer, transplant recipients, and people with significant burns. After organ transplantation or in otherwise immunocompromised persons, there are high rates of cytomegalovirus pneumonia. Those with viral infections may be secondarily infected with

1826-448: Is associated with an increased risk of pneumonia. Approximately 10% of people who require mechanical ventilation develop ventilator-associated pneumonia , and people with a gastric feeding tube have an increased risk of developing aspiration pneumonia . Moreover, the misplacement of a feeding tube can lead to aspiration pneumonia. 28% of tube malposition results in pneumonia. As with Avanos Medical 's feeding tube placement system,

1909-506: Is available for adults, and has been found to decrease the risk of invasive pneumococcal disease by 74%, but there is insufficient evidence to suggest using the pneumococcal vaccine to prevent pneumonia or death in the general adult population. The CDC recommends that young children and adults over the age of 65 receive the pneumococcal vaccine, as well as older children or younger adults who have an increased risk of getting pneumococcal disease. The pneumococcal vaccine has been shown to reduce

1992-644: Is due primarily to cytokine -induced systemic inflammation . In the developed world , these infections are most common in people returning from travel or in immigrants. Around the world, parasitic pneumonia is most common in the immunodeficient. Idiopathic interstitial pneumonia or noninfectious pneumonia is a class of diffuse lung diseases . They include diffuse alveolar damage , organizing pneumonia , nonspecific interstitial pneumonia , lymphocytic interstitial pneumonia , desquamative interstitial pneumonia , respiratory bronchiolitis interstitial lung disease , and usual interstitial pneumonia . Lipoid pneumonia

2075-801: Is due to infections caused primarily by bacteria or viruses and less commonly by fungi and parasites . Although more than 100 strains of infectious agents have been identified, only a few are responsible for the majority of cases. Mixed infections with both viruses and bacteria may occur in roughly 45% of infections in children and 15% of infections in adults. A causative agent may not be isolated in about half of cases despite careful testing. In an active population-based surveillance for community-acquired pneumonia requiring hospitalization in five hospitals in Chicago and Nashville from January 2010 through June 2012, 2259 patients were identified who had radiographic evidence of pneumonia and specimens that could be tested for

2158-460: Is important to treatment, as it correlates to which pathogens are likely suspects, which mechanisms are likely, which antibiotics are likely to work or fail, and which complications can be expected based on the person's health status. Community-acquired pneumonia (CAP) is acquired in the community, outside of health care facilities. Compared with healthcare-associated pneumonia, it is less likely to involve multidrug-resistant bacteria. Although

2241-445: Is increased. Bacteria are the most common cause of community-acquired pneumonia (CAP), with Streptococcus pneumoniae isolated in nearly 50% of cases. Other commonly isolated bacteria include Haemophilus influenzae in 20%, Chlamydophila pneumoniae in 13%, and Mycoplasma pneumoniae in 3% of cases; Staphylococcus aureus ; Moraxella catarrhalis ; and Legionella pneumophila . A number of drug-resistant versions of

2324-448: Is known as lobar pneumonia. However, findings may vary, and other patterns are common in other types of pneumonia. Aspiration pneumonia may present with bilateral opacities primarily in the bases of the lungs and on the right side. Radiographs of viral pneumonia may appear normal, appear hyper-inflated, have bilateral patchy areas, or present similar to bacterial pneumonia with lobar consolidation. Radiologic findings may not be present in

2407-587: Is most common in the Southwestern United States. The number of cases of fungal pneumonia has been increasing in the latter half of the 20th century due to increasing travel and rates of immunosuppression in the population. For people infected with HIV/AIDS , PCP is a common opportunistic infection . A variety of parasites can affect the lungs, including Toxoplasma gondii , Strongyloides stercoralis , Ascaris lumbricoides , and Plasmodium malariae . These organisms typically enter

2490-530: Is not cost-effective and typically does not alter management. For people who do not respond to treatment, sputum culture should be considered, and culture for Mycobacterium tuberculosis should be carried out in persons with a chronic productive cough. Microbiological evaluation is also indicated in severe pneumonia, alcoholism, asplenia , immunosuppression, HIV infection, and those being empirically treated for MRSA of pseudomonas. Although positive blood culture and pleural fluid culture definitively establish

As such these beliefs were afforded protection under the Equality Act. The original tribunal's ruling that the belief was "not worthy of respect in a democratic society" was overturned. The appeal was supported by interventions by

2656-465: Is sometimes called MCAP (medical care–associated pneumonia). People may become infected with pneumonia in a hospital; this is defined as pneumonia not present at the time of admission (symptoms must start at least 48 hours after admission). It is likely to involve hospital-acquired infections , with higher risk of multidrug-resistant pathogens. People in a hospital often have other medical conditions, which may make them more susceptible to pathogens in

2739-723: Is sometimes more broadly applied to any condition resulting in inflammation of the lungs (caused for example by autoimmune diseases , chemical burns or drug reactions); however, this inflammation is more accurately referred to as pneumonitis . Factors that predispose to pneumonia include smoking, immunodeficiency , alcoholism, chronic obstructive pulmonary disease , sickle cell disease (SCD), asthma , chronic kidney disease , liver disease , and biological aging . Additional risks in children include not being breastfed , exposure to cigarette smoke and other air pollution, malnutrition, and poverty. The use of acid-suppressing medications – such as proton-pump inhibitors or H2 blockers –

2822-432: Is treated with antibiotics . If the pneumonia is severe, the affected person is generally hospitalized. Oxygen therapy may be used if oxygen levels are low. Each year, pneumonia affects about 450 million people globally (7% of the population) and results in about 4 million deaths. With the introduction of antibiotics and vaccines in the 20th century, survival has greatly improved. Nevertheless, pneumonia remains

2905-498: Is uncommon, but occurs more commonly in individuals with weakened immune systems due to AIDS, immunosuppressive drugs , or other medical problems. It is most often caused by Histoplasma capsulatum , Blastomyces , Cryptococcus neoformans , Pneumocystis jiroveci ( pneumocystis pneumonia , or PCP), and Coccidioides immitis . Histoplasmosis is most common in the Mississippi River basin , and coccidioidomycosis

2988-705: Is well known for its research on aid effectiveness . CGD president Nancy Birdsall developed in 2010 a Cash on Delivery (COD) Aid initiative, aiming to improve aid effectiveness by focusing foreign aid on outcomes, not inputs. In 2008, CGD produced a compilation of essays edited by Nancy Birdsall called "The White House and the World: A Global Development Agenda for the Next U.S. President". These essays give policy recommendations to solve international problems, such as global health, foreign aid policy, migration, global warming and foreign direct investment. CGD recently published

Other research topics listed on their website include capital flows / financial crises , debt relief , environmental issues , economic growth, governance /democracy, international financial institutions , finance, food and agriculture, inequality , population, poverty, private investment, security and development, and data sets and resources. CGD receives funding from foundations, governments, individuals, and corporations. The organization publishes information on its website for all grants and donations received that are above $ 100,000. CGD received

3154-535: The University of Pennsylvania 's Global Go-To Think Tanks rating index found that during the period 2014-2018 the Center for Global Development received the second-highest amount of funding from outside the United States compared to any other think tank, with a total of more than US$ 37 million, though the center was commended for being "remarkably transparent about its funding sources." The center considers itself

3237-647: The CORTRAK* 2 EAS, which was recalled in May 2022 by the FDA due to adverse events reported, including pneumonia, caused a total of 60 injuries and 23 patient deaths, as communicated by the FDA. For people with certain variants of the FER gene , the risk of death is reduced in sepsis caused by pneumonia. However, for those with TLR6 variants, the risk of getting Legionnaires' disease

CGD's stated mission is "to reduce global poverty and inequality by encouraging policy change in the United States and other rich countries through rigorous research and active engagement with the policy community. The center considers itself to be a "think and do" tank, with an emphasis on producing research that is channeled into practical policy proposals. CGD has carried out debt-relief programs in Nigeria and Liberia . CGD vice president Todd Moss first proposed

From November 2007 to November 2012, CGD published Carbon Monitoring For Action (CARMA), a searchable database that estimated carbon emissions of power plants and power companies around the world. CGD hosts about 200 public and private events

3818-513: The above infections are becoming more common, including drug-resistant Streptococcus pneumoniae (DRSP) and methicillin-resistant Staphylococcus aureus (MRSA). The spreading of organisms is facilitated by certain risk factors. Alcoholism is associated with Streptococcus pneumoniae , anaerobic organisms , and Mycobacterium tuberculosis ; smoking facilitates the effects of Streptococcus pneumoniae , Haemophilus influenzae , Moraxella catarrhalis , and Legionella pneumophila . Exposure to birds

3901-560: The additional feature of pulmonary consolidation . Pneumonia is most commonly classified by where or how it was acquired: community-acquired, aspiration, healthcare-associated , hospital-acquired , and ventilator-associated pneumonia. It may also be classified by the area of the lung affected: lobar, bronchial pneumonia and acute interstitial pneumonia ; or by the causative organism. Pneumonia in children may additionally be classified based on signs and symptoms as non-severe, severe, or very severe. The setting in which pneumonia develops

3984-421: The affected lung, and increased, rather than decreased, vocal resonance distinguishes pneumonia from a pleural effusion . A chest radiograph is frequently used in diagnosis. In people with mild disease, imaging is needed only in those with potential complications, those not having improved with treatment, or those in which the cause is uncertain. If a person is sufficiently sick to require hospitalization,

4067-421: The alveoli, resulting in the consolidation seen on chest X-ray. Viruses may reach the lung by a number of different routes. Respiratory syncytial virus is typically contracted when people touch contaminated objects and then touch their eyes or nose. Other viral infections occur when contaminated airborne droplets are inhaled through the nose or mouth. Once in the upper airway, the viruses may make their way into

4150-576: The approach and the Gates Foundation and five countries gave $ 1.5 billion to create a vaccine against strains of pneumonia . In cooperation with Foreign Policy , CGD has published the Commitment to Development Index since 2003. The annual index ranks countries based on how their foreign aid, trade, migration, investment, environment, security and technology policies encourage global development. The Center for Global Development in Europe

4233-517: The bacteria Streptococcus pneumoniae , Staphylococcus aureus , or Haemophilus influenzae , particularly when other health problems are present. Different viruses predominate at different times of the year; during flu season , for example, influenza may account for more than half of all viral cases. Outbreaks of other viruses also occur occasionally, including hantaviruses and coronaviruses. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can also result in pneumonia. Fungal pneumonia

4316-449: The blood. Once in the lungs, bacteria may invade the spaces between cells and between alveoli, where the macrophages and neutrophils (defensive white blood cells ) attempt to inactivate the bacteria. The neutrophils also release cytokines, causing a general activation of the immune system. This leads to the fever, chills, and fatigue common in bacterial pneumonia. The neutrophils, bacteria, and fluid from surrounding blood vessels fill

4399-516: The body through direct contact with the skin, ingestion, or via an insect vector. Except for Paragonimus westermani , most parasites do not specifically affect the lungs but involve the lungs secondarily to other sites. Some parasites, in particular those belonging to the Ascaris and Strongyloides genera, stimulate a strong eosinophilic reaction, which may result in eosinophilic pneumonia . In other infections, such as malaria, lung involvement

4482-546: The cause and support decisions about who should receive antibiotics. Antibiotics are encouraged if the procalcitonin level reaches 0.25 μg/L, strongly encouraged if it reaches 0.5 μg/L, and strongly discouraged if the level is below 0.10 μg/L. In people requiring hospitalization, pulse oximetry , chest radiography and blood tests – including a complete blood count , serum electrolytes , C-reactive protein level, and possibly liver function tests – are recommended. The diagnosis of influenza-like illness can be made based on

4565-427: The condition, but they are associated with side effects. Zanamivir or oseltamivir decrease the chance that people who are exposed to the virus will develop symptoms; however, it is recommended that potential side effects are taken into account. Smoking cessation and reducing indoor air pollution , such as that from cooking indoors with wood, crop residues or dung , are both recommended. Smoking appears to be

4648-404: The diagnosis is unlikely. However, the underlying cause can be difficult to confirm, as there is no definitive test able to distinguish between bacterial and non-bacterial cause. The overall impression of a physician appears to be at least as good as decision rules for making or excluding the diagnosis. The World Health Organization has defined pneumonia in children clinically based on either

4731-508: The diagnosis of the type of micro-organism involved, a positive sputum culture has to be interpreted with care for the possibility of colonisation of respiratory tract. Testing for other specific organisms may be recommended during outbreaks, for public health reasons. In those hospitalized for severe disease, both sputum and blood cultures are recommended, as well as testing the urine for antigens to Legionella and Streptococcus . Viral infections, can be confirmed via detection of either

4814-758: The early stages of the disease, especially in the presence of dehydration, or may be difficult to interpret in the obese or those with a history of lung disease. Complications such as pleural effusion may also be found on chest radiographs. Laterolateral chest radiographs can increase the diagnostic accuracy of lung consolidation and pleural effusion. A CT scan can give additional information in indeterminate cases and provide more details in those with an unclear chest radiograph (for example occult pneumonia in chronic obstructive pulmonary disease). They can be used to exclude pulmonary embolism and fungal pneumonia , and detect lung abscesses in those who are not responding to treatments. However, CT scans are more expensive, have

4897-582: The forest fires to specific companies. The GFW platform has been used in a number of notable applications. The forest change data have been used to measure global deforestation rates and to detect and monitor illegal clearing activity, primarily in Indonesia. The NASA Active Fires data, displayed within GFW Fires, have been used to identify illegal burning that has caused the 2015 Southeast Asian haze crisis (see Haze crisis ). Multinational companies use

4980-422: The highest rating (five stars) from Transparify for its open disclosure of funding in 2014 and 2015. In 2013, the government of Norway gave CGD $ 5 million to support its work on tropical forests and development. That support was cited in a New York Times article about think tank funding. A report by the Center for International Policy 's Foreign Influence Transparency Initiative of the top 50 think tanks on

5063-634: The hospital. Ventilator-associated pneumonia occurs in people breathing with the help of mechanical ventilation. Ventilator-associated pneumonia is specifically defined as pneumonia that arises more than 48 to 72 hours after endotracheal intubation . Several diseases can present with similar signs and symptoms to pneumonia, such as: chronic obstructive pulmonary disease, asthma, pulmonary edema , bronchiectasis , lung cancer, and pulmonary emboli . Unlike pneumonia, asthma and COPD typically present with wheezing, pulmonary edema presents with an abnormal electrocardiogram , cancer and bronchiectasis present with

5146-585: The latter are no longer rare in CAP, they are still less likely. Prior stays in healthcare-related environments such as hospitals, nursing homes, or hemodialysis centers or a history of receiving domiciliary care can increase patients' risk for CAP caused by multidrug-resistant bacteria. Health care–associated pneumonia (HCAP) is an infection associated with recent exposure to the health care system, including hospitals, outpatient clinics, nursing homes , dialysis centers, chemotherapy treatment, or home care . HCAP

5229-431: The lower airways, reflexes of the glottis , actions of complement proteins and immunoglobulins are important for protection. Micro aspiration of contaminated secretions can infect the lower airways and cause pneumonia. The progress of pneumonia is determined by the virulence of the organism; the amount of organism required to start an infection; and the body's immune response against the infection. Most bacteria enter

5312-464: The lungs via small aspirations of organisms residing in the throat or nose. Half of normal people have these small aspirations during sleep. While the throat always contains bacteria, potentially infectious ones reside there only at certain times and under certain conditions. A minority of types of bacteria such as Mycobacterium tuberculosis and Legionella pneumophila reach the lungs via contaminated airborne droplets. Bacteria can also spread via

5395-418: The lungs, many viruses simultaneously affect other organs and thus disrupt other body functions. Viruses also make the body more susceptible to bacterial infections; in this way, bacterial pneumonia can occur at the same time as viral pneumonia. Pneumonia is typically diagnosed based on a combination of physical signs and often a chest X-ray . In adults with normal vital signs and a normal lung examination,

5478-433: The lungs, where they invade the cells lining the airways, alveoli, or lung parenchyma . Some viruses such as measles and herpes simplex may reach the lungs via the blood. The invasion of the lungs may lead to varying degrees of cell death. When the immune system responds to the infection, even more lung damage may occur. Primarily white blood cells, mainly mononuclear cells , generate the inflammation. As well as damaging

5561-400: The lymph nodes in the neck , joint pain , or a middle ear infection . Viral pneumonia presents more commonly with wheezing than bacterial pneumonia. Pneumonia was historically divided into "typical" and "atypical" based on the belief that the presentation predicted the underlying cause. However, evidence has not supported this distinction, therefore it is no longer emphasized. Pneumonia

5644-524: The most prominent sign. The typical signs and symptoms in children under five are fever, cough, and fast or difficult breathing. Fever is not very specific, as it occurs in many other common illnesses and may be absent in those with severe disease, malnutrition or in the elderly. In addition, a cough is frequently absent in children less than 2 months old. More severe signs and symptoms in children may include blue-tinged skin , unwillingness to drink, convulsions, ongoing vomiting, extremes of temperature, or

5727-638: The policy community. Past Sabot speakers include Lawrence Summers , Ngozi Okonjo-Iweala , Lord Nicholas Stern , Kemal Dervis and Kenneth Rogoff . In 2019, a tribunal brought by former visiting fellow Maya Forstater at the Central London Employment Tribunal found in favour of CGD in the initial stage of a claim of belief discrimination by a former worker. Employment Judge James Tayler found that Forstater's " gender critical " views were "incompatible with human dignity and fundamental rights of others" and that they did "not have

5810-421: The probability of Mycoplasma pneumoniae . In general, in adults, investigations are not needed in mild cases. There is a very low risk of pneumonia if all vital signs and auscultation are normal. C-reactive protein (CRP) may help support the diagnosis. For those with CRP less than 20 mg/L without convincing evidence of pneumonia, antibiotics are not recommended. Procalcitonin may help determine

5893-532: The protected characteristic of philosophical belief" under the UK Equality Act 2010 . However, in June 2021, an Employment Appeal Tribunal led by Akhlaq Choudhury overturned this judgment, finding that Forstater's beliefs were covered under the protected belief characteristic within the meaning of the Equality Act. The appeal was allowed after the appeal tribunal concluded the belief that "biological sex

5976-497: The responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination . Chest X-rays , blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis , chronic obstructive pulmonary disease (COPD), sickle cell disease , asthma , diabetes , heart failure,

6059-500: The responsible pathogen. Most patients (62%) had no detectable pathogens in their sample, and unexpectedly, respiratory viruses were detected more frequently than bacteria. Specifically, 23% had one or more viruses, 11% had one or more bacteria, 3% had both bacterial and viral pathogens, and 1% had a fungal or mycobacterial infection. "The most common pathogens were human rhinovirus (in 9% of patients), influenza virus (in 6%), and Streptococcus pneumoniae (in 5%)." The term pneumonia

6142-519: The risk of community acquired pneumonia in people with chronic obstructive pulmonary disease, but does not reduce mortality or the risk of hospitalization for people with this condition. People with COPD are recommended by a number of guidelines to have a pneumococcal vaccination. Other vaccines for which there is support for a protective effect against pneumonia include pertussis , varicella , and measles .
