Epidemiologist

Investigating disease outbreaks; collecting and analysing surveillance data; designing surveys and studies; writing reports that help governments decide on vaccination, water, sanitation and screening programmes; training health staff.

A day in the work
Your morning might start by checking the day's disease reports from districts and spotting a sudden rise in fever cases in one block. You call the local health officer, then travel to the village to talk to families, note when people fell ill and collect water and food samples with the lab team. Back at the desk in the evening, you put the cases into a spreadsheet, draw a graph and look for what the sick people have in common. Then you write a short report that tells the district what to do next, such as chlorinate wells or run a vaccination drive.

1. Step 1 · Class 9–12Build a base in Biology, Maths and basic statistics. Get used to reading graphs and tables. Take PCB if you want MBBS. Other subject choices still lead to public health through a bachelor's degree and an MPH.
2. Step 2 · Class 12 and afterDoctor route: NEET-UG, then MBBS (about 4.5 years plus a 1-year internship). Non-doctor route: a bachelor's degree in life sciences, nursing, pharmacy, BDS/AYUSH, statistics or a related subject. Check the exact eligibility of each MPH or M.Sc you want.
3. Step 3 · 2–3 yearsPostgraduate study. MBBS doctors can take MD Community Medicine (3 years, through NEET-PG or INI-CET). Others can take an MPH or M.Sc in Epidemiology or Biostatistics (2 years). AIIMS Rishikesh's MPH is a full-time 2-year course. Entry is by an entrance exam and an interview, and you need at least 50% in the two stages combined (2026 prospectus). (reported — check with the official body)
4. Step 4 · 1–3 yearsField experience. The India Epidemic Intelligence Service (EIS) at NCDC is a 2-year, on-the-job training in outbreak response. Its 2024 flyer lists the entry routes: MD in community medicine or public health, or other MD/MBBS plus years of experience. The age limit is 45. ICMR-NIE's MPH (Epidemiology and Health Systems) asks for MBBS plus 3 years of public health work.
5. Step 5 · JobsApply for posts such as district or state epidemiologist under the Integrated Disease Surveillance Programme (IDSP) and National Health Mission, NCDC or ICMR institutes, and WHO or NGO projects. Many posts are contractual, and states set their own qualifications and pay. (reported — check with the official body)
6. OptionalPhD in epidemiology or public health for research and teaching careers, for example at ICMR institutes or medical colleges.

• Doctor routeClass 12 (PCB) → NEET-UG → MBBS → MD Community Medicine → India EIS or a government public-health post
• Public-health route (non-doctor)Bachelor's degree (life sciences, nursing, pharmacy, BDS/AYUSH, etc.) → MPH or M.Sc Epidemiology → district or state epidemiologist and research roles. NCDC's 2026 contract notice accepts a life-science B.Sc plus MPH, DPH or MAE and 2 years' experience for some public-health posts (reported).
• Numbers routeBachelor's with Statistics or Maths → M.Sc Biostatistics (for example at ICMR-NIE, Chennai) → biostatistician or data roles on disease studies

Fees from: AIIMS Rishikesh MPH prospectus, January 2026 · ICMR-NIE M.Sc Biostatistics brochure 2026. Fees change every year — check the college's own fee page before you pay.

Pay depends a lot on the employer: contract posts under state health missions usually pay less than central institutes, international agencies or research jobs, and it rises with experience, a doctor's qualification and seniority.

The AIIMS Rishikesh MPH prospectus (2026) reserves seats for SC, ST, OBC and EWS candidates, and PwD candidates pay no application fee. Selected students must be declared medically fit by the institute's medical board, so students with disabilities should check this with the institute.

• Class 7–9Do a tiny survey of 15–20 classmates or neighbours (for example, how many had a cold or fever last month). Tally the answers and draw a bar chart. This is the basic habit of epidemiology.
• Class 10–12Start a free beginner course in statistics or data handling on SWAYAM or NPTEL, and practise reading health graphs.Open link ↗
• College or afterRead NCDC's pages on the India EIS programme and its internship programme. Note what each asks for, and start learning Excel or a free tool like R.Open link ↗

• Epidemiology is usually a postgraduate field. Most people start with a first degree and specialise afterwards.
• The India EIS is training, not a degree on its own. NCDC says EIS officers can also earn a Master in Applied Epidemiology degree from HNB Medical Education University, Uttarakhand.
• Many senior government epidemiologist posts prefer doctors with MD Community Medicine. Non-doctors with an MPH or M.Sc do get district-level posts, so check each notification (reported).
• Field work often needs the local language. AIIMS Rishikesh's own prospectus says Hindi up to Class 10 is desirable because its MPH involves a lot of field work.
