304-460: A basic level of medical care and disease prevention. A major public health concern in developing countries is poor maternal and child health , exacerbated by malnutrition and poverty coupled with governments' reluctance in implementing public health policies. Developed nations are at greater risk of certain public health crises, including childhood obesity, although overweight populations in low- and middle-income countries are catching up. From
380-620: A basic level of medical care and disease prevention. As a result, a large majority of disease and mortality in developing countries results from and contributes to extreme poverty . For example, many African governments spend less than $ 100 USD per person per year on health care, while, in the United States, the federal government spent approximately $ 10,600 USD per capita in 2019. However, expenditures on health care should not be confused with spending on public health. Public health measures may not generally be considered "health care" in
456-410: A component of preventive medicine and public health. It is implemented as part of primary care rather than a specialty in its own right. Valles argues that the term social medicine has a narrower and more biomedical focus than the term population health. The purpose of a public health intervention is to prevent and mitigate diseases, injuries , and other health conditions. The overall goal
532-441: A country's overall health care system. Many interventions of public health interest are delivered outside of health facilities , such as food safety surveillance, distribution of condoms and needle-exchange programs for the prevention of transmissible diseases. Public health requires Geographic Information Systems (GIS) because risk, vulnerability and exposure involve geographic aspects. A dilemma in public health ethics
608-512: A delicate role in global politics . It must maintain good relationships with each of the many countries in which it is active. As a result, it may only report results within a particular country with the agreement of the country's government. Because some governments regard the release of any information on disease outbreaks as a state secret, this can place the WHO in a difficult position. The WHO coordinated International Outbreak Alert and Response
684-722: A disease can be expensive, and distinguishing between two diseases can be prohibitively difficult in many countries. One standard means of determining if a person has had a particular disease is to test for the presence of antibodies that are particular to this disease. In the case of H5N1, for example, there is a low pathogenic H5N1 strain in wild birds in North America that a human could conceivably have antibodies against. It would be extremely difficult to distinguish between antibodies produced by this strain, and antibodies produced by Asian lineage HPAI A(H5N1) . Similar difficulties are common, and make it difficult to determine how widely
760-579: A disease may have spread. There is currently little available data on the spread of H5N1 in wild birds in Africa and Asia. Without such data, predicting how the disease might spread in the future is difficult. Information that scientists and decision makers need to make useful medical products and informed decisions for health care, but currently lack include: Surveillance of H5N1 in humans, poultry, wild birds, cats and other animals remains very weak in many parts of Asia and Africa. Much remains unknown about

When public health initiatives began to emerge in England in modern times (18th century onwards) there were three core strands of public health which were all related to statecraft: Supply of clean water and sanitation (for example London sewerage system ); control of infectious diseases (including vaccination and quarantine ); an evolving infrastructure of various sciences, e.g. statistics, microbiology, epidemiology, sciences of engineering.

Pielke worries about "stealth issue advocacy" in population health.

Lifestyle medicine uses individual lifestyle modification to prevent or revert disease and can be considered

Supporters argue by presenting evidence that smoking is one of the major killers, and that therefore governments have a duty to reduce the death rate, both through limiting passive (second-hand) smoking and by providing fewer opportunities for people to smoke. Opponents say that this undermines individual freedom and personal responsibility, and worry that
2356-1515: Is to improve the health of individuals and populations, and to increase life expectancy . Public health is a complex term, composed of many elements and different practices.

Other important sub-fields include environmental health , community health , behavioral health , health economics , public policy , mental health , health education , health politics , occupational safety , disability , gender issues in health, and sexual and reproductive health . Modern public health practice requires multidisciplinary teams of public health workers and professionals. Teams might include epidemiologists , biostatisticians , physician assistants , public health nurses , midwives , medical microbiologists , pharmacists , economists , sociologists , geneticists , data managers , environmental health officers ( public health inspectors ), bioethicists , gender experts, sexual and reproductive health specialists, physicians , and veterinarians .

For example, recently, health aid

Its current priorities include communicable diseases , particularly HIV/AIDS , Ebola , COVID-19 , malaria and tuberculosis ; non-communicable diseases such as heart disease and cancer; healthy diet , nutrition, and food security ; occupational health ; and substance abuse .

In the United States, a history of underinvestment in public health undermined the public health workforce and support for population health, long before the pandemic added to stress, mental distress, job dissatisfaction, and accelerated departures among public health workers. Health aid to developing countries is an important source of public health funding for many developing countries. Health aid to developing countries has shown

For example, in the United States , state and local health departments are on the front line of public health initiatives.

Critics have argued that public health tends to place more focus on individual factors associated with health at the expense of factors operating at the population level.

A central challenge to securing health equity is that the same social structures that contribute to health inequities also operate and are reproduced by public health organizations. In other words, public health organizations have evolved to better meet the needs of some groups more than others. The result is often that those most in need of preventative interventions are least likely to receive them and interventions can actually aggravate inequities as they are often inadvertently tailored to

For example, mandating the use of seat belts in cars can save countless lives and contribute to the health of a population, but typically money spent enforcing this rule would not count as money spent on health care.

These goals in their entirety encompass the entire spectrum of development across nations, however Goals 1–6 directly address health disparities , primarily in developing countries. These six goals address key issues in global public health , poverty , hunger and food security , health, education, gender equality and women's empowerment , and water and sanitation .
