What is Epidemiologist?

An Epidemiology study investigates how often a particular disease occurs in a group of people and its reasons. Similar to pathology and clinical findings, Epidemiology is an integral part of the initial findings of a disease.

  1. It is applied to a group of people and not individuals
  2. Deals with a particular population having health risk

Works in the following method:

Target Population → Study Population → Study Sample

For instance, a target population is a group of people vulnerable to arthritis. Study Population is a subgroup in the age group 45-55 and belongs to 8 different communities. The study population is the source of a randomly picked sample.

What does an Epidemiologist Do?

An Epidemiologist has various responsibilities. Here are important ones compiled:

  • Diagnose various causes and effects of a particular disease and the parasites involved
  • Identify the transmission modes of disease and the parasites
  • Undertake well laid out plans and investigation of human and animal diseases and come out with preventive measures
  • Communicate all findings with physicians and policymakers through brainstorming sessions and formulate the best possible preventive care and curative measures

What are Epidemiology Types?

There are four sections of Epidemiology Types:

  1. Cross-sectional studies
  2. Case-control studies
  3. Cohort studies
  4. Intervention studies

Cross-sectional studies can identify the occurrence of a particular condition or characteristics in a group or population. It is a descriptive study, but the findings often help determine causative or risk factors associated with the illness. One example is the relationship between cataract and vitamin deficiency was diagnosed with a Cross-sectional study.

Case-control studies can compare a person with symptoms (called a ‘case’) with a ‘control group’ which doesn’t have symptoms of the disease. Further, the conditions to which all ‘cases’ and the ‘control group’ members have exposed are determined. If the requirements differ, then the medical condition/disease reasons are suspected, and further investigations are carried out in this direction. 

Cohort studies is a method where a group’s habits or characteristics over a while are studied. For instance, Software Engineers with smoking habits are continuously under monitor for, say, forty years. The findings of the first twenty years revealed that Engineers who were heavy smokers were prone to die from lung cancer. Similarly, the Millenium baby study, the National Health Study of School-going children, and many other cohort studies have been conducted.

Intervention studies are different from the three studies mentioned above. All the studies discussed above are observational. The intervention study conducts a treatment or procedure on a particular random group, and other groups are left untouched. Suppose the characteristics of the intervened group and unattended group are drastically different. In that case, the intervention is the root cause for the differences.
