Infectious Disease Epidemiology

Infectious disease epidemiology is the study of how diseases spread, their patterns, and their impacts on populations. It involves tracking outbreaks, understanding how infections are transmitted, and identifying risk factors. Epidemiologists collect data to analyze trends and develop strategies for prevention and control, such as vaccinations and public health policies. By studying interactions between pathogens (like bacteria and viruses), hosts (people and animals), and environments, this field aims to reduce the incidence of infectious diseases and improve overall public health.
