What is a clinical epidemiologist?

A clinical epidemiologist is a research professional in the medical field who studies the occurrence and frequency of diseases and major health events in specific populations. Epidemiology isn't only relevant to medicine but also to fields in the social sciences and statistical analysis. Clinical epidemiologists aren't doctors, although they study and identify the causes of diseases in a way similar to doctors. Instead, they advise doctors and other medical professionals regarding the appropriate treatments for various conditions and understand the intricacies and efficacy of various medicines.

The data collection and analysis the clinical epidemiologists perform help prevent potential outbreaks and can keep members of a population safe from disease. Their job duties typically include:

  • collect human tissue and blood samples to learn more about pathogens and their origin

  • create and manage health plans to help slow or stop the spread of a disease or minimise the impact of a health crisis

  • develop a preventative action plan for potential health events

  • research the relation between infectious diseases and their transmission and the populations and cultures where they occur

  • gather patient and population data by conducting interviews and distributing surveys to gain a better understanding of a public health event

  • manage the planning, implementation and improvement of public healthcare services

  • collaborate with other medical professionals, such as oncologists, to create effective treatments and improve patient healthcare results

  • create studies that analyse and predict risk factors and causes of human and animal diseases, transmission, treatment and prevention

  • analyse and improve current public health responses to control pandemics and chronic ailments
