👉 An epidemiologist is a scientist who studies the spread and transmission of diseases. They work on understanding how diseases are transmitted, how they affect people's health, and what interventions can be taken to prevent or treat them. Epidemiologists use a variety of methods, including surveys, interviews, and statistical analysis, to gather data about disease patterns and their impact on populations. Their research helps inform public health policies and practices aimed at reducing the spread of diseases and improving healthcare outcomes.
