Public Health Fields and Specialties

Public Health Fields refers to the science and practice of preventing disease, prolonging life and promoting health. Public health covers all areas of society, including individuals, public and private organisations, communities and individuals. The field is made up of multidisciplinary teams composed of public health professionals. They work together to improve people’s health and quality life. The main areas of specialty in this field are environmental health and community health, epidemiology, global and managerial health, as well as health policy and management.

Environmental Health

Environmental health is a topic of public health that addresses both natural and human-made environmental factors that can affect human health. This includes the natural environment (soil, air, water) as well the social, biological, and chemical aspects.

Environmental health specialists study and analyze the effects of environmental quality on human health. They develop, promote, and enforce environmentally-related guidelines, policies, laws, and regulations in order to create and sustain healthy living environments for people. The focus of environmental health specialists is on one aspect, such as air pollution, sustainable growth, chemical safety, effects, climate change, or social determinants.

Community Health

The community health workers provide education and facilitation services to improve the quality of life and health in the communities they serve. They organize outreach programs that involve the community regarding education and health access. From a public health expert’s point of view, community health workers collect data to advocate for community needs.

Public health workers could work for nonprofits, public healthcare departments, schools, or other private organizations. According to the U.S. Bureau of Labor Statistics (USBS), community health worker jobs will grow by 17% between 2020-2030, which is faster than average for all occupations.

Epidemiology

Epidemiologists examine the causes and patterns behind diseases and injuries within a particular community or population. They do this to reduce the chance of negative outcomes and improve health through community education, research and advocacy on health policy.

Data and results may be collected and analyzed by epidemiologists using interviews, surveys, and observations. In order to identify the root causes of problems in health, epidemiologists may draw blood or take fluid samples. Epidemicologists, like those in other public-health institutions and systems, report their findings and recommendations to policymakers, health professionals, and the public in order to manage public healthcare initiatives.

Global Health

According to the National Institutes of Health, global health can be defined as research, study, and practice that broadens the public health field into a global view for people around the world. The work of global healthcare is done by many organizations, including the World Health Organization, World Food Programme and UNICEF. The majority of global health workers work for non-profits or government agencies.

Health Policy

One of the most important fields in public health is health policy. This includes roles such as healthcare policy analyst, public health researcher, and manager of health services. Health policy professionals are advocates and researchers in the field of public health. They might act as liaisons between public-health professionals, organizations, and government agencies.
