CHENNAI — More than 150 public‑health officials, veterinarians, environmental scientists and policymakers gathered for a two‑day conference on the “One Health” framework in Chennai, Tamil Nadu, from March 20‑21, 2026. Organized by the State Health Department in partnership with the Indian Council of Medical Research and the Tamil Nadu Veterinary and Animal Sciences University, the event aimed to deepen coordination across human, animal and ecosystem health sectors amid rising zoonotic threats.
What Happened
The conference opened with a keynote address by Dr R. K. Mohan, director of the National Centre for Disease Control (NCDC). He highlighted the COVID‑19 pandemic as a wake‑up call, noting that fragmented data sharing between hospitals, livestock farms and wildlife monitoring units had delayed early detection of outbreaks. “We must institutionalize data sharing between hospitals, livestock farms and wildlife monitoring units,” he said, citing a 2024 study that linked a surge in Nipah virus cases to unregulated fruit‑bat habitats near human settlements.
Panel discussions focused on operationalizing One Health in India. Participants reviewed recent legislation, including the 2025 Wildlife Protection Amendment that mandates joint surveillance teams for emerging diseases, and the 2025 National Animal Health Policy, which allocates ₹1.2 billion for integrated diagnostic labs. A workshop on field surveillance techniques and laboratory biosafety was held for district health officers and veterinary officers.
A key proposal was a unified digital platform to collate real‑time reports of animal morbidity, human disease outbreaks and environmental indicators. Dr Sanjay Patel, a veterinary epidemiologist at the University of Madras, presented a prototype “OneHealth Hub” that links state health information systems with the Ministry of Environment’s remote‑sensing data. He warned that without such tools, “delays in detecting spillover events could cost lives and livelihoods.”
The World Health Organization’s South‑East Asia Regional Office highlighted funding opportunities under the WHO‑UNICEF Joint Programme on Pandemic Preparedness, urging Indian states to submit joint proposals. In closing, Tamil Nadu Health Minister M. K. Mohanlal pledged to create a state‑level One Health coordination cell by the end of 2026, announcing an initial budget of ₹500 million to upgrade laboratory networks and train personnel across the three sectors.
Why It Matters
India’s diverse ecosystems and dense human‑livestock interactions make zoonotic diseases a persistent threat. The One Health framework, which integrates human, animal and environmental health, has gained traction worldwide after the COVID‑19 pandemic exposed gaps in cross‑sectoral coordination. By institutionalizing data sharing and joint surveillance, the conference seeks to prevent future spillovers and reduce the economic and health costs of outbreaks.
The proposed digital platform could streamline reporting and early warning, potentially shortening the time between detection and response. If implemented, it would also provide a model for other Indian states and for the national government, aligning with the 2025 National Action Plan for Pandemic Preparedness.
Background and Context
The One Health concept has been promoted by the World Health Organization, the Food and Agriculture Organization and the World Organisation for Animal Health since the early 2000s. In India, the National One Health Policy was first drafted in 2019, but implementation has been uneven. Tamil Nadu, with its large livestock population and proximity to wildlife corridors, has been a focal point for zoonotic research.
The 2025 Wildlife Protection Amendment, passed by Parliament, requires wildlife authorities to collaborate with health and veterinary departments when monitoring diseases that could cross species barriers. The 2025 National Animal Health Policy, approved by the Ministry of Agriculture, earmarks ₹1.2 billion for establishing integrated diagnostic laboratories across the country, a significant increase from the previous fiscal year’s allocation of ₹800 million.
Competing Claims and Uncertainty
While the conference participants largely agreed on the need for integrated surveillance, some experts cautioned about the feasibility of rapid data integration. Dr Anil Kumar, a public health analyst at the Indian Council of Medical Research, noted that data ownership and privacy concerns could hinder real‑time sharing. “There is a risk that institutions may be reluctant to share data that could reflect poorly on their performance,” he said.
Others questioned the sustainability of the proposed budget. The ₹500 million earmarked by the Tamil Nadu government covers laboratory upgrades and training but does not account for ongoing operational costs. A study by the Centre for Policy Research in 2023 estimated that maintaining integrated diagnostic labs would require an additional ₹200 million annually.
The WHO‑UNICEF Joint Programme on Pandemic Preparedness offers funding, but the application process is competitive and requires detailed joint proposals from multiple ministries. The timeline for disbursement is unclear, raising doubts about whether the funds will arrive before the next fiscal year.
What to Watch Next
1. Implementation of the One Health Coordination Cell – The Tamil Nadu government has pledged to establish a state‑level cell by the end of 2026. Observers will monitor the appointment of staff, the creation of protocols, and the integration of existing surveillance networks.
2. Deployment of the OneHealth Hub – Dr Patel’s prototype will need to be tested in pilot districts. Success will depend on interoperability with existing health information systems and the willingness of local health workers to adopt new reporting tools.
3. Funding Flow from WHO‑UNICEF – The status of joint proposals submitted by Tamil Nadu and other states will indicate whether international funding can supplement domestic budgets.
4. Legislative Follow‑through – The 2025 Wildlife Protection Amendment’s requirement for joint surveillance teams will need to be operationalized. State wildlife departments will need to allocate resources and personnel to collaborate with health and veterinary agencies.
5. Evaluation of Early Warning Systems – Independent assessments of the new surveillance mechanisms will be critical. Researchers from the Tamil Nadu Veterinary and Animal Sciences University plan to conduct a six‑month evaluation of the pilot districts.
Conclusion
The Chennai conference marked a significant step toward institutionalizing the One Health approach in India, bringing together stakeholders from human health, veterinary science and environmental monitoring. The proposed digital platform and coordination cell promise to close surveillance gaps that have historically hampered rapid response to zoonotic threats. However, the success of these initiatives will hinge on sustained funding, clear data‑ownership frameworks, and political commitment to enforce cross‑sectoral mandates. As India prepares for future pandemics, the outcomes of this conference could set a precedent for integrated health governance across the country.
