What do epidemiologists study

Epidemiologists study the distribution and determinants of diseases, injuries, and other health outcomes in human populations. They use this information to develop and test interventions that can improve health and prevent disease in communities.

Some key areas of study for epidemiologists include:

  • Identifying and tracking the spread of infectious diseases, such as influenza and COVID-19
  • Investigating the causes of chronic diseases, such as cancer and heart disease
  • Examining risk factors for injury and violence, such as substance abuse and access to firearms
  • Assessing the effectiveness of public health interventions, such as vaccination programs and health education campaigns
  • Evaluating the impact of environmental factors, such as air pollution and access to clean water, on health outcomes

Epidemiologists use a variety of research methods, including observational studies, clinical trials, and surveys, to gather and analyze data on health outcomes and risk factors. They also collaborate with other public health professionals, such as physicians and health educators, to develop and implement interventions to improve the health of populations.
