When disease outbreaks strike, India needs skilled professionals who can investigate them quickly, analyze data effectively, and implement control measures that save lives. Building this workforce of trained epidemiologists has become a national priority, especially after the COVID-19 pandemic exposed significant gaps in public health capacity. The solution lies in comprehensive field epidemiology training programs that combine real-world experience with rigorous mentorship.

India’s approach to training disease detectives
India faces a unique challenge. With a population of 1.3 billion people spread across 36 states and over 700 districts, the country needs thousands of epidemiologists working at every level of the health system. However, during the COVID-19 pandemic, the Ministry of Health and Family Welfare identified over 200 vacant epidemiologist positions across the country. While some states like Kerala, Maharashtra, and Tamil Nadu have established public health cadres, most states lack a designated workforce trained in outbreak investigation and surveillance.
The National Centre for Disease Control has emerged as the central hub for building this critical capacity. Through its Field Epidemiology Training Programs, NCDC provides hands-on training that transforms medical officers into skilled disease detectives capable of responding to public health emergencies.
The India Epidemic Intelligence Service program
Established in 2012 through collaboration between NCDC and the U.S. Centers for Disease Control and Prevention, the India Epidemic Intelligence Service represents the country’s flagship advanced epidemiology training initiative. This two-year program follows a mentorship-based approach where officers learn through actual public health service rather than classroom lectures alone.
The program employs what experts call “learning through service” – participants work on real outbreak investigations, surveillance system evaluations, and public health research while receiving guidance from experienced mentors. As of 2020, the program had graduated 46 officers, with 96% working in public health positions, demonstrating its success in building a professional epidemiology workforce.
Real-world impact of trained officers
The impact of these trained epidemiologists extends far beyond numbers. Since 2012, EIS officers have responded to over 140 public health emergencies, including outbreaks of acute diarrheal diseases, vaccine-preventable diseases, vector-borne illnesses, and zoonotic diseases. Their investigations have led to actionable recommendations that have saved lives and prevented further disease spread.
One notable success involved investigating mysterious cases of acute encephalitis syndrome in Muzaffarpur, Bihar. Through systematic investigation, officers identified the illness as hypoglycemic encephalopathy linked to litchi fruit consumption. Based on their findings, health authorities implemented prevention measures including minimizing litchi consumption and providing evening meals for children, which helped prevent subsequent outbreaks.
Building capacity at multiple levels
Recognizing that a single advanced program cannot meet India’s vast training needs, the Ministry of Health and Family Welfare expanded the approach in 2016 by adopting a three-tiered training system: advanced, intermediate, and frontline programs designed to build capacity at national, state, and district levels.
The intermediate training track
The Intermediate Field Epidemiology Training Programme is a one-year, on-the-job training designed for state and district-level health officials. This program targets epidemiologists and surveillance officers working in permanent or contractual positions who need practical skills without leaving their posts for extended periods.
Participants complete five contact sessions and 47 weeks of field activities at their regular duty stations. Each officer works with an expert mentor and co-mentor to complete core learning activities including surveillance data analysis, outbreak investigations, epidemiological studies, and scientific report writing. This flexible approach allows states to build capacity without disrupting essential health services.
Frontline and specialized programs
From 2016 to 2020, three institutions implemented frontline training in eight states and trained 273 district-level officers using a three-month basic field epidemiology curriculum. Additionally, NCDC has launched innovative programs like SectorConnect, which uses a One Health approach to train professionals from human health, animal husbandry, wildlife, and food safety sectors together.
The path forward
Despite these achievements, significant challenges remain. India needs to train over 7,000 epidemiologists to meet international health regulation targets. The COVID-19 pandemic demonstrated both the critical importance of trained epidemiologists and the severe shortage of such professionals across the country.
Expanding the workforce strategically
Meeting this goal requires a coordinated national effort. The target is to have one trained field epidemiologist per 200,000 population, aligned with WHO’s International Health Regulations requirements. This expansion must happen at all three tiers simultaneously – advanced programs for national and state leadership, intermediate programs for state and district capacity, and frontline training for peripheral health workers.
Success will depend on several factors: creating additional training hubs at existing public health institutions, increasing cohort sizes, recruiting and retaining graduates through professional recognition and clear career pathways, establishing networks of alumni who can provide mentorship and surge capacity during emergencies, and ensuring representation from all states and diverse professional backgrounds.
Integrating academic recognition
One persistent challenge has been the lack of formal academic degree recognition for field epidemiology training. While participants in the India EIS Programme can now earn a Master in Applied Epidemiology degree from H.N.B. Medical Education University, Uttarakhand, broader integration with academic institutions remains necessary. Professional recognition and defined career advancement opportunities will help attract more government officers to these programs.
Building resilience for future threats
The investment in epidemiological training goes beyond responding to individual outbreaks. A robust network of trained epidemiologists strengthens disease surveillance systems, improves program monitoring, enables evidence-based policymaking, and builds institutional memory within the health system. During the COVID-19 pandemic, 86% of program alumni and 98% of current officers engaged in pandemic response activities, demonstrating the program’s value during major health emergencies.
These professionals established surveillance systems, investigated COVID-19 clusters, conducted screening and contact tracing, managed response logistics, implemented infection control measures, and led serosurveys. Their contributions have been instrumental in managing the pandemic across multiple states and districts.
The road ahead requires sustained commitment from government, academic institutions, and international partners. By scaling up field epidemiology training across all levels, India can build the epidemiological workforce needed to protect public health, respond effectively to disease threats, and strengthen the health system for future challenges.
What do you think? How can India ensure that every district has access to trained epidemiologists? What steps would make careers in field epidemiology more attractive to medical professionals?
