The Union Ministry of Health and Family Welfare has significantly strengthened the Integrated Disease Surveillance Programme (IDSP) by launching new Standard Operating Procedures (SOPs) for bio-emergency response. These SOPs establish clear protocols for Centre-State coordination during public health emergencies such as disease outbreaks, pandemics, and biological threats.

The revised IDSP framework was developed in the wake of the Nipah virus outbreak response in January 2026, which exposed coordination gaps between central and state health agencies. The new SOPs define trigger points for escalation, communication hierarchies, laboratory confirmation timelines, and resource mobilisation protocols between the National Centre for Disease Control (NCDC), State Surveillance Units (SSUs), and district-level rapid response teams.

A key component of the revamped framework is the operationalisation of the National One Health Mission, which is being implemented under the joint oversight of PM-STIAC (Prime Minister's Science, Technology and Innovation Advisory Council) and ICMR (Indian Council of Medical Research). The One Health approach integrates human, animal, and environmental health surveillance to detect zoonotic disease threats at the source.

The IDSP was originally launched in 2004 and is implemented in all states and union territories through a network of state, district, and peripheral units. The programme uses an 'S-P-L' reporting system — Syndromic, Presumptive, and Laboratory — to track disease trends in real time. The bio-emergency SOPs add a new 'crisis coordination layer' atop this surveillance backbone, ensuring faster containment when a threat is confirmed.

For RAS aspirants, IDSP falls under Public Health Administration and Centre-State relations in the governance syllabus. The National One Health Mission is a significant inter-ministerial initiative relevant to Paper II (Indian Administration).
