Introduction

  • 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)
