- "Public 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'."
Preventive measures to promote health and prevent disease, including vaccination programs and epidemiology.
Epidemiology: The study of how diseases spread in populations and how to prevent or control them.
Biostatistics: The use of statistical methods for public health research and analysis.
Environmental health: The study of the effects of the environment on human health and how to reduce or prevent harmful exposures.
Communicable diseases: Infectious diseases that can be transmitted between people or animals, such as measles, tuberculosis, and influenza.
Non-communicable diseases: Chronic diseases that are not contagious, such as diabetes, heart disease, and cancer.
Occupational health: The study of how work environment can affect employee health and safety.
Health behavior and health education: How to promote healthy choices and lifestyles through education and behavior change.
Health services administration: The management of healthcare systems and organizations.
Health policy and management: The development and implementation of policies and programs to improve population health.
Health economics: The study of the financial aspects of the healthcare system.
Global health: The study of health issues and challenges that transcend national borders, such as pandemics, poverty, and access to healthcare.
Disaster response: The planning and management of public health responses to natural disasters, bioterrorism, and other emergency situations.
Medical ethics: The ethical considerations involved in medical research, patient care, and public health policy.
Nutrition and food safety: The study of the role of nutrition in health and how to ensure safe food systems.
Healthcare informatics: The use of technology to store and analyze healthcare data for improved patient care and population health.
Preventive medicine: This branch focuses on preventing diseases, illness, and injuries within the military. They provide guidance and recommendations for maintaining a healthy environment, adequate nutrition and hydration, and prevent infectious diseases.
Occupational medicine: This branch focuses on the health of military personnel in the workplace. They determine the effects of exposure to chemicals and radiation, assess physical demands of tasks on soldiers, and provide assistance to injured soldiers.
Aerospace medicine: Aerospace medicine is concerned with the effects of air and space travel on military personnel. They study the effects of high-altitude conditions on military aviators and help prevent motion sickness caused by being in space.
Environmental health: Environmental health is the branch of public health that focuses on protecting the health of military personnel through reducing environmental risks. They monitor the quality of water, air, and food sources and ensure compliance with occupational and environmental health standards.
Epidemiology: Epidemiology is concerned with the public health aspects of disease outbreaks within the military. They track the spread of infectious diseases and implement measures to reduce the incidence of such diseases.
Health promotion and education: This branch focuses on promoting healthy lifestyles and behaviors among military personnel. They teach about injury prevention, nutrition, exercise, and stress management.
Disaster response: Disaster response is the public health branch that focuses on providing medical assistance and care during natural disasters and emergencies. They provide immediate medical assistance to affected military personnel.
Behavioral health: Behavioral health is the branch of public health that focuses on the prevention and treatment of mental health and substance abuse disorders. They provide psychiatric care and treatment to military personnel experiencing mental health issues.
Global health: Global health deals with public health problems that affect multiple countries worldwide. This branch focuses on the health of military personnel travelling to other countries on humanitarian missions or field operations.
Biodefense and biosecurity: Biodefense and biosecurity are the branches of public health that focus on identifying, detecting, and responding to biological threats, including bioterrorism, and potential pandemics. They work on developing plans for response to biological or chemical attacks within the military organization.
- "Analyzing the determinants of health of a population and the threats it faces is the basis for public health."
- "Epidemiology, biostatistics, social sciences and management of health services are all relevant."
- "Other important sub-fields include environmental health, community health, behavioral health, health economics, public policy, mental health, health education, health politics, occupational safety, disability, oral health, gender issues in health, and sexual and reproductive health."
- "Public health, together with primary care, secondary care, and tertiary care, is part of a country's overall healthcare system."
- "Common public health initiatives include promotion of hand-washing and breastfeeding, delivery of vaccinations, promoting ventilation and improved air quality both indoors and outdoors, suicide prevention, smoking cessation, obesity education, increasing healthcare accessibility, and distribution of condoms to control the spread of sexually transmitted diseases."
- "There is a significant disparity in access to health care and public health initiatives between developed countries and developing countries, as well as within developing countries."
- "In developing countries, public health infrastructures are still forming. There may not be enough trained healthcare workers, monetary resources, or, in some cases, sufficient knowledge to provide even 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."
- "Great Britain became a leader in the development of public health initiatives, beginning in the 19th century, due to the fact that it was the first modern urban nation worldwide."
- "The public health initiatives that began to emerge initially focused on sanitation (for example, the Liverpool and London sewerage systems), control of infectious diseases (including vaccination and quarantine) and an evolving infrastructure of various sciences, e.g. statistics, microbiology, epidemiology, sciences of engineering."
