Work Activities

As an Epidemiologist, you will be finding ways to tackle new diseases and help prevent it from spreading to lots of people.

You might work in many different field, or specialise in one particular area. These might include:

  • environmental diseases
  • infectious diseases
  • occupational health
  • children’s health
  • chronic diseases

You will investigate these areas and write specialist reports for the government and the general public.

There are two types of Epidemiologists: Field Epidemiologists and Clinical Epidemiologists.

Field Epidemiologists

The NHS employs Field Epidemiologists.

As a Field Epidemiologist, you could have a role in examining outbreaks of infectious diseases such as meningitis, measles, flu or food poisoning. Or, you could be monitoring the health effects caused by exposure to potentially dangerous things, such as the radio waves produced by mobiles and telephone masts. Your day-to-day work could also include:

  • interviewing people or administering surveys
  • developing ideas and explanations about possible causes
  • using the results of investigations (such as blood, water or airborne samples)
  • informing what needs to be done to control the spread of an infection or minimise harm
  • monitoring the effect of actions taken
  • informing the development of policies associated with infectious diseases or environmental hazards

Clinical Epidemiologists

As a Clinical Epidemiologist, you will be with the patient in the hospital looking for common symptoms of disease. You might take some swab samples and send them to the laboratory.

You will then look at the disease under the microscope and investigate it fully.

You will need to gather the necessary data from your patient. This might include comparing them to healthy patients to identify possible patterns. Once you have collected all the data you need, you will then take this to a Field Epidemiologist, where they will analyse the data.

Being able to read, write and speak Welsh may be an advantage when you’re looking for work in Wales.
