Public healthPublic health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents.
Centers for Disease Control and PreventionThe Centers for Disease Control and Prevention (CDC) is the national public health agency of the United States. It is a United States federal agency under the Department of Health and Human Services, and is headquartered in Atlanta, Georgia. The agency's main goal is the protection of public health and safety through the control and prevention of disease, injury, and disability in the US and worldwide. The CDC focuses national attention on developing and applying disease control and prevention.
Health equityHealth equity arises from access to the social determinants of health, specifically from wealth, power and prestige. Individuals who have consistently been deprived of these three determinants are significantly disadvantaged from health inequities, and face worse health outcomes than those who are able to access certain resources. It is not equity to simply provide every individual with the same resources; that would be equality. In order to achieve health equity, resources must be allocated based on an individual need-based principle.
Chinese Center for Disease Control and PreventionThe Chinese Center for Disease Control and Prevention (CCDC; ) is an institution directly under the National Health Commission, based in Changping District, Beijing, China. Established in 1983, it works to protect public health and safety by providing information to enhance health decisions, and to promote health through partnerships with provincial health departments and other organizations.
Preventive healthcarePreventive healthcare, or prophylaxis is the application of healthcare measures to prevent diseases. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes which begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention. Each year, millions of people die of preventable deaths.
World Health OrganizationThe World Health Organization (WHO) is a specialized agency of the United Nations responsible for international public health. It is headquartered in Geneva, Switzerland and has six regional offices and 150 field offices worldwide. The WHO was established on 7 April 1948 and convened its first meeting on 24 July of that year. It incorporated the assets, personnel, and duties of the League of Nations' Health Organization and the Paris-based Office International d'Hygiène Publique, including the International Classification of Diseases (ICD).
European Centre for Disease Prevention and ControlThe European Centre for Disease Prevention and Control (ECDC) is an agency of the European Union (EU) whose mission is to strengthen Europe's defences against infectious diseases. It covers a wide spectrum of activities, such as: surveillance, epidemic intelligence, response, scientific advice, microbiology, preparedness, public health training, international relations, health communication, and the scientific journal Eurosurveillance. The centre was established in 2004 and is headquartered in Solna, Sweden.
Healthcare in the United StatesHealthcare in the United States is provided by a complex mix of public and private entities, with healthcare facilities and providers largely owned and operated by private sector businesses. As of the early 21st century, the U.S. healthcare system is characterized by a combination of public programs, private insurance, and out-of-pocket payments. The U.S. is the only developed country without a system of universal healthcare, and a significant proportion of its population lacks health insurance.
COVID-19 pandemicThe COVID-19 pandemic, also known as the coronavirus pandemic, is a global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide in 2020. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) on 30 January 2020.
Outline of health sciencesThe following outline is provided as an overview of and topical guide to health sciences: Health sciences are those sciences which focus on health, or health care, as core parts of their subject matter. Health sciences relate to multiple academic disciplines, including STEM disciplines and emerging patient safety disciplines (such as social care research). Medicine is an applied science or practice of the diagnosis, treatment, and prevention of disease.
Professional degrees of public healthThe Master of Public Health or Master of Philosophy in Public Health (MPH), Master of Science in Public Health (MSPH), Master of Medical Science in Public Health (MMSPH) and the Doctor of Public Health (DrPH), International Masters for Health Leadership (IMHL) are interdisciplinary professional degrees awarded for studies in areas related to public health. The MPH degree focuses on public health practice, as opposed to research or teaching.
Global healthGlobal health is the health of the populations in the worldwide context; it has been defined as "the area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide". Problems that transcend national borders or have a global political and economic impact are often emphasized. Thus, global health is about worldwide health improvement (including mental health), reduction of disparities, and protection against global threats that disregard national borders, including the most common causes of human death and years of life lost from a global perspective.
Doctor of Public HealthA Doctor of Public Health (abbr. DrPH, Dr.PH. or D.P.H.; Latin doctor publica sanitas) is a doctoral degree awarded in the field of Public Health. DrPH is an advanced and terminal degree that prepares its recipients for a career in advancing public health practice, leadership, research, teaching, or administration. The first DrPH degree was awarded by Harvard Medical School in 1911. According to the United Nations, the world faces unprecedented challenges such as climate change, noncommunicable diseases, aging populations, health crises, a widening wealth gap, and the overreliance on the internet.
Global governanceGlobal governance refers to institutions that coordinate the behavior of transnational actors, facilitate cooperation, resolve disputes, and alleviate collective action problems. Global governance broadly entails making, monitoring, and enforcing rules. Within global governance, a variety of types of actors – not just states – exercise power. Governance is thus broader than government. Global governance began in the mid-19th century. It became particularly prominent in the aftermath of World War I, and more so after the end of World War II.
Transgender health careTransgender health care includes the prevention, diagnosis and treatment of physical and mental health conditions, as well as sex reassignment therapies, for transgender individuals. A major component of transgender health care is gender-affirming care, the medical aspect of gender transition. Questions implicated in transgender health care include gender variance, sex reassignment therapy, health risks (in relation to violence and mental health), and access to healthcare for trans people in different countries around the world.
Health educationHealth education is a profession of educating people about health. Areas within this profession encompass environmental health, physical health, social health, emotional health, intellectual health, and spiritual health, as well as sexual and reproductive health education. Health education can be defined as the principle by which individuals and groups of people learn to behave in a manner conducive to the promotion, maintenance, or restoration of health.
Cardiovascular diseaseCardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), stroke, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, abnormal heart rhythms, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis. The underlying mechanisms vary depending on the disease.
Pan American Health OrganizationThe Pan American Health Organization (PAHO) is a specialized agency of the United Nations (UN) in charge of international health cooperation in the Americas. It fosters technical cooperation among member countries to fight communicable and noncommunicable diseases, strengthen health systems, and respond to emergencies and disasters. It has 35 Member States and four Associate Members in the region. Headquartered in Washington, D.C., PAHO is the regional office for the World Health Organization in the Americas, and the health organization of the Inter-American System.
Health policyHealth policy can be defined as the "decisions, plans, and actions that are undertaken to achieve specific healthcare goals within a society". According to the World Health Organization, an explicit health policy can achieve several things: it defines a vision for the future; it outlines priorities and the expected roles of different groups; and it builds consensus and informs people. Health policy often refers to the health-related content of a policy.
Community healthCommunity health refers to simple health services that are delivered by laymen outside hospitals and clinics. Community health is also the subset of public health that is taught to and practiced by clinicians as part of their normal duties. Community health volunteers and community health workers work with primary care providers to facilitate entry into, exit from and utilization of the formal health system by community members.
