What is an Epidemiologist: High Salary & How to Become One
Explore epidemiologist as a job role: qualifications, salary, and responsibilities.

When an epidemic or endemic situation occurs, people look for a healthcare professional, such as a doctor, nurse, pharmacist, or technician. But someone else is also there who plays a major role in managing such a disease outbreak, an epidemiologist. There are backstage professionals who work to find out what that disease is, how it spreads, how to manage it, and how to prevent such a condition.
If someone wants to build their career in epidemiology, then this will give an idea, starting from the basics.
What is an epidemiologist?
Epidemiologists are professionals in the field of healthcare specialising in researching diseases. They will observe disease in terms of occurrence, risk factor, and progression; after that, they form preventive strategies and policy implementation for the general public.
Epidemiologists are the bridge that connects healthcare policy implementation via medical knowledge. For instance, they figure out why asthma is so widespread in certain areas or how long it is going to take before a new virus becomes a pandemic.
Responsibilities of an epidemiologist:
- Collect and analyse samples and data related to chronic or infectious disease
- Communicating research findings to stakeholders, policymakers, or officials
- Formulate an initiative for a public health program
- Promote outcome benefits with an education programme.
- Funding proposal drafting for research purposes
When there is a disease outbreak or a critical public health situation, they take on responsibilities of contact tracing, transmission details, and passive surveillance for finding the disease origins and contaminants.
Epidemiologist vs Virologist
Generally, people get confused between those two professions. Epidemiologists concentrate on disease occurrence, progression, and the formation of preventive policy. They are field detectives of disease. Whereas virologists study viruses that cause disease, how viruses work on the body, what effect they cause, and how they mutate in the laboratory. They work as laboratory detectives for disease.
What are the types of epidemiologists?
There are the following types of epidemiologists based on speciality and field of work:
Infection control epidemiologist:
They are also called hospital epidemiologists. They are centred around infection control, from recognising disease causes to formulating preventive policy measures. They establish awareness among the general public and healthcare workers about the disease.
Pharmaceutical epidemiologist:
They work with pharmaceutical drugs and their research. Their duties include discovering how a drug or group of drugs interacts with the population across a specific period. They examine the spread of conditions and their effects on people and what treatments produce potentially positive results. They formulate reports and policies for drug safety and efficacy.
Medical epidemiologist:
A medical epidemiologist works around the clinical aspects of disease, such as clinical pathology, treatment options, and observation of disease outbreaks. For this, they require knowledge of clinical medicine and a medical degree to practise medicine, such as a Doctor of Medicine (MD). They may also create public health programmes to prevent disease.
Field epidemiologist
Individuals who work in field epidemiology intervene on the ground level in communities with severe, acute public health crises. Some issues become unexpected and significant enough that they have to travel to the site and give a time-sensitive response.
Molecular epidemiologist
They use biology to identify risk factors associated with genes, the cause of disease, and to understand diseases at the molecular level.
Veterinary epidemiologist
They work with animal species to find the spreading patterns of disease. They use knowledge of techniques and principles of field work to apply and study measures that may be used to control disease occurrences in animal populations.
Supervisory Epidemiologist:
Supervisors are typically in charge of larger workgroups (which usually consist of other epidemiologists and assistants), making sure that they comply with rules and follow widely accepted practices of the industry.
How to become an epidemiologist?
For becoming an epidemiologist, there is a medical or non-medical route one can choose based on their interests.
Non-medical route:
Step 1: Bachelor's-level course: this usually takes 3-4 years, based on the course after 10+2 with PCB
- B.Sc. Microbiology
- B.Sc. Biotechnology
- B.Sc. Life Sciences / Zoology
- B.Sc. Nursing
- B.Sc. Statistics / Biostatistics
- BVSc (Veterinary Science)
- BPT (Physiotherapy)
Step 2: Master's degrees
- MPH (Master of Public Health)
- M.Sc. Epidemiology
- M.Sc. Biostatistics
Medical route:
Step 1: Bachelor's-level course: After passing the NEET UG entrance exam, it takes around 5-5.5 years
- MBBS
- BDS
Step 2: Master course:
- MD Community Medicine/Preventive & Social Medicine (3 years via NEET-PG) or MPH for MBBS
- MPH or Public Health Dentistry (3-year via NEET MDS) for dental graduates
Optional Higher Studies
A PhD in epidemiology, public health, or biostatistics (3–5 years) may be a good step into research leadership roles, university professorships, or senior positions in agencies such as the Indian Council of Medical Research (ICMR), the National Centre for Disease Control (NCDC), and the World Health Organization (WHO).
What is the career scope and job opportunities for an epidemiologist?
The scope for epidemiology jobs is increasing rapidly in the post-COVID-19 era as people are becoming aware of it. Epidemiologists can find employment in many sectors in India, such as:
• Health departments at the state and central levels
• Research institutions such as ICMR and NCDC.
• Pharmaceutical companies doing drug safety and clinical epidemiology.
• Hospitals with infection control and epidemiology departments.
• International organisations working in India.
On a global level, countries like the UK, the USA, and Australia are recruiting epidemiologists for research purposes.
Epidemiologist Salary: India and Abroad
An epidemiologist's salary changes with employment in the government or private sector.
- For a non-medical background with a BSc + MPH/ M.Sc. epidemiology degree, a fresher can start with 3.5-6 LPA and earn up to 15 LPA.
- With a medical background and an MBBS + master's degree, one can start earning 6 - 9 LPA, and a senior with 10+ years of experience can get 25+ LPA.
- With a dental background, they can start at 4-5.5 LPA and get up to 12-16 LPA with experience.
By Sector
Salary pay scale changes as the working sector of epidemiologists changes, such as
- Government sectors like NCDS, ICMR, or state health departments provide starting from ₹4 LPA to 20+ LPA based on experience
- International organisations or NGOs like WHO and UNICEF give ₹6 LPA to ₹18 LPA.
- The pharmaceutical or biotech industry provides ₹7 – 20 LPA
- An academic career path in colleges or teaching institutes gives ₹6 – 15 LPA, plus a research grant
Abroad
The salary scale becomes higher abroad, like in the US, UK, Canada, and the Gulf, up to ₹35 to ₹60 LPA or sometimes more with experience. The presence of MD/MPH-certified experts means that they can serve both in the realm of clinical settings and in public health, leading to better-paying positions for the professionals.
Epidemiologists have a contributory role in providing a response to the government in an epidemic situation, vaccine planning, and execution. Also, prepare the hospital for future crisis situations by providing proper policies. If you are interested in biology and data, and you want a profession that isn’t limited to treatment in the clinic, epidemiology is a great intersection of science, research, and public service.
