Cornerstone of National Measles-Rubella (MR) Elimination Programme under National Centre for Vector Borne Diseases Control (NCVBDC) and Integrated Disease Surveillance Programme (IDSP)
Shifted to case-based Acute Fever and Rash (AFR) surveillance since 2021 (from outbreak-based system)
Real-time reporting through Integrated Health Information Portal (IHIP)
Aligned with WHO SEARO guidelines and Global Measles Elimination Strategy
India targeting measles and rubella elimination by 2026 (incidence <1 case per million population)
Mandatory notification from public and private sectors; integrated with U-WIN, ABDM, MR Campaign 2025-26 and RBSK
Objectives
Early detection of every suspected AFR case to interrupt transmission chains
Laboratory confirmation of all suspected cases
Rapid outbreak investigation and response (Outbreak Response Immunization – ORI)
Monitor trends, classify cases (indigenous/imported) and generate evidence for WHO certification
Maintain surveillance sensitivity: ≥2 non-measles AFR cases per 100,000 population per year
Case Definitions (IDSP P-form 2024)
Suspected Case
Any person with fever AND maculopapular (non-vesicular) rash OR
Any person in whom a clinician or health worker suspects measles infection
Probable Case
Suspected case with epidemiological link to a laboratory-confirmed measles case
Laboratory-Confirmed Case
IgM positive in serum (collected within 28 days of rash onset) OR
Measles virus detection by RT-PCR (throat swab/urine within 5 days of rash)
Epidemiologically Confirmed Case
Suspected case with epidemiological link to a laboratory-confirmed case (no lab sample)
Discarded Case
Suspected case with negative laboratory result and no epidemiological link
Surveillance Methods
Passive Surveillance
Routine reporting from all health facilities (public/private) via IHIP
Active Surveillance
House-to-house search in outbreak zones by ASHA/ANM
School and Anganwadi screening (linked with RBSK)
Sentinel Surveillance
Designated MR laboratories and district hospitals
Laboratory Network
27 accredited MR laboratories (expanded from 13 in 2017)
Sample collection: Serum for IgM ELISA; throat swab/urine for RT-PCR
Turnaround time: Results within 7–14 days
Investigation & Response Timeline
Day 1: Immediate IHIP notification of every suspected case (within 24 hours)
Day 3: Case investigation form completed; blood sample despatched to MR lab
Day 7: Preliminary lab results; outbreak investigation if cluster detected
Outbreak Response Immunization (ORI): MR vaccine to all children 6 months–14 years in affected area within 72 hours of confirmation
Contact tracing and vitamin A supplementation
Key Performance Indicators
Non-measles AFR rate: ≥2 per 1,00,000 population
Timely notification: ≥80%
Adequate sample collection & transport: ≥80%
Completeness of reporting: ≥90%
Integration with Child Health Programmes
RBSK: Screening for fever/rash in school children
RKSK: Adolescent awareness
UIP/U-WIN: MR vaccine tracking via ABHA
FBNC/SAANS: Management of complications in neonates/infants
ABDM: Digital case records and follow-up
Current Status (2026)
National Zero Measles-Rubella Elimination Campaign 2025-26 completed
Current MR-1 & MR-2 coverage >92%
Significant decline in measles outbreaks; India on track for WHO verification of elimination by end-2026
Continued focus on high-risk areas (urban slums, migrant populations, international borders)
