**Summary:**
The article discusses the use of environmental surveillance, specifically wastewater surveillance, as an early warning system for disease outbreaks. It explains how pathogens shed in waste can be tracked to monitor disease prevalence and variants within a community. Traditionally, infection levels were determined through clinical case detection, but this method misses asymptomatic or untested individuals. Environmental surveillance offers a more comprehensive picture, often preceding a rise in infections detected clinically. While wastewater surveillance has been used globally for diseases like polio and COVID-19, the Indian Council of Medical Research (ICMR) is expanding its use to monitor 10 viruses across 50 cities in India. The article advocates for improved data sharing, standardized protocols, and a national wastewater surveillance system in India. It also touches upon emerging surveillance methods like analyzing audio samples for respiratory conditions.

**India to Expand Wastewater Surveillance for Disease Outbreaks**
*New Delhi, October 1, 2025* – The Indian Council of Medical Research (ICMR) is set to significantly expand its wastewater surveillance program to monitor 10 viruses across 50 cities, aiming to provide early warnings for potential disease outbreaks, the Hindu reports. This initiative builds upon existing wastewater surveillance programs initiated for polio in Mumbai in 2001 and later for COVID-19 in several cities during the pandemic.
Wastewater surveillance involves tracking pathogens shed in human waste, providing a broader picture of disease prevalence than traditional clinical case detection, which may miss asymptomatic or untested individuals. Scientists analyze samples from sewage treatment plants and other sources to detect and track pathogens, using protocols that ensure consistency and comparability of data. Whole-genome sequencing further helps identify variants of pathogens.
“Environmental surveillance offers a crucial advantage by often preceding a rise in clinical infections by more than a week,” explained Professor Gautam Menon, Dean of Research at Ashoka University, in a published opinion on the topic.
The ICMR’s expanded program aims to pick up any increase in viral load within community settings, extending its surveillance efforts beyond COVID-19. This includes monitoring for avian influenza virus, particularly in areas experiencing outbreaks.
Experts emphasize the importance of improved data sharing and standardized protocols across institutions to maximize the effectiveness of the surveillance system. They advocate for programmatic approaches that integrate wastewater surveillance with routine disease surveillance, ultimately leading to the development of a national wastewater surveillance system for India.
Beyond wastewater, the article highlights emerging surveillance technologies, such as analyzing audio samples for coughs in public places to track respiratory conditions, indicating the ever-evolving possibilities of environmental surveillance.
