Three-Pronged Strategy of NVBDCP
Under NVBDCP, the three-pronged strategy for prevention and control of vector-borne diseases is:
- Disease management - early case detection, complete treatment, strengthening referral services, epidemic preparedness and rapid response
- Integrated Vector Management (IVM) - Indoor Residual Spraying (IRS) in high-risk areas, insecticide-treated bed nets (ITNs), larvivorous fish, anti-larval measures, source reduction, environmental engineering
- Supportive interventions - Behaviour Change Communication (BCC), public-private partnership, inter-sectoral convergence, human resource development, operational research, monitoring and evaluation, web-based MIS, vaccination against JE, annual MDA against lymphatic filariasis
National Framework for Malaria Elimination in India (2016-2030)
Launched in February 2016. India's vision shifted from malaria control to sustained malaria elimination.
Goals
In line with WHO Global Technical Strategy (GTS) for Malaria 2016-2030 and Asia Pacific Leaders Malaria Alliance (APLMA) Malaria Elimination Roadmap:
- Eliminate malaria (zero indigenous cases) throughout the entire country by 2030
- Maintain malaria-free status in areas where transmission has been interrupted and prevent re-introduction
Time-Bound Objectives
| Target Year | Objective |
|---|
| 2022 | Transmission interrupted and zero indigenous cases in all 26 States/UTs (Categories 1 and 2 as of 2014) |
| 2024 | Incidence reduced to < 1 case per 1000 population in all States/UTs and their districts |
| 2027 | Indigenous transmission interrupted in all States/UTs of India |
| 2030 | Malaria eliminated throughout entire country; re-establishment of transmission prevented |
Programme Phasing - Classification of States/UTs (2014)
States are categorized based on API (Annual Parasite Incidence) as the primary criterion, with ABER (Annual Blood Examination Rate) and SPR (Slide Positivity Rate) as secondary criteria:
| Category | Definition | No. of States/UTs |
|---|
| Category 0 - Prevention of re-establishment | States with zero indigenous cases | None currently |
| Category 1 - Elimination phase | API < 1, all districts reporting API < 1 | 15 States/UTs |
| Category 2 - Pre-elimination phase | API < 1, but some districts reporting API ≥ 1 | 11 States |
| Category 3 - Intensified control phase | API ≥ 1 | 10 States/UTs |
Category 1 States/UTs: Himachal Pradesh, Punjab, J&K, Kerala, Manipur, Puducherry, Chandigarh, Uttarakhand, Haryana, Sikkim, Rajasthan, Daman & Diu, Goa, Delhi, Lakshadweep
Category 2 States: Bihar, Tamil Nadu, Telangana, UP, Karnataka, West Bengal, Andhra Pradesh, Assam, Maharashtra, Gujarat, Nagaland
Category 3 States (High Burden): Andaman & Nicobar, Madhya Pradesh, Dadar & Nagar Haveli, Jharkhand, Arunachal Pradesh, Chhattisgarh, Odisha, Meghalaya, Tripura, Mizoram
District-Level Stratification (District as Unit of Planning)
Each district stratifies its PHCs and sub-centres into 5 strata based on API:
- Zero cases
- API > 0 to < 1
- API 1 to < 2
- API 2 to < 5
- API ≥ 5
This allows Category 2 states to initiate elimination activities in low-burden districts even while others are still in the intensified control phase.
Broad Strategies of the Malaria Elimination Framework
- Early diagnosis and radical treatment
- Case-based surveillance and rapid response
- Integrated Vector Management (IVM):
- Indoor Residual Spray (IRS)
- Long-Lasting Insecticidal Nets (LLINs) / ITNs
- Larval Source Management (LSM)
- Epidemic preparedness and early response
- Monitoring and evaluation
- Advocacy, coordination and partnerships
- Behaviour Change Communication (BCC) and community mobilization
- Programme planning and management
Category-Specific Interventions
Category 3 - Intensified Control Phase (API ≥ 1)
- Massive scaling up of disease management and preventive approaches
- Screening of all fever cases suspected for malaria
- Classification of areas by local malaria epidemiology; tailored interventions
- Strengthening intersectoral collaboration; special interventions for tribal populations and hard-to-reach/conflict-affected areas
- One-stop centres or mobile clinics on fixed days in tribal areas for malaria diagnosis and treatment
- Timely referral and treatment of severe malaria to reduce mortality
- Strengthening district/sub-district hospitals as per Indian Public Health Standards for severe malaria management
- Robust supply chain management system
- Optimum surveillance using microscopy and RDTs
- Equipping all health institutions with microscopy, RDTs, and injectable artemisinin derivatives for severe malaria
Category 2 - Pre-Elimination Phase (API < 1, some districts API ≥ 1)
- Setting up elimination surveillance system
- Initiating elimination phase activities in districts where API has been reduced below 1
- Planning based on epidemiological investigation and classification of each case and focus
Category 1 - Elimination Phase (API < 1 in all districts)
- All efforts directed at interrupting local transmission in all active foci
- Mandatory notification of each malaria case from private sector and all other health facilities
- Adequate case-based surveillance and complete case management
- Investigation and classification of all malaria foci
- Total coverage of all active foci by effective vector control measures
- Early detection and treatment using Active Case Detection (ACD) and Passive Case Detection (PCD)
- State and national level malaria elimination database established
- Interventions for mobile and migrant populations screening
- Effective epidemic forecasting and response system
- Quality assurance of all medicines and diagnostics
- Establishment of State Reference Laboratory - all positive slides sent for confirmation; 100% notification to laboratory after elimination achieved; immediate SMS/e-mail alert for each positive case with name, gender, address, date, parasite type
Category 0 - Prevention of Re-establishment
- Detect any re-introduced case
- Immediately notify all detected cases
- Determine causes of resumed local transmission
- Apply rapid curative and preventive measures
- Prevent re-introduction of malaria
- Maintain malaria-free status
Surveillance System
- Active Case Detection (ACD): Blood smears collected by MPWs/ANMs during fortnightly house visits in rural areas
- Passive Case Detection (PCD): Fever cases reporting to peripheral health volunteers/ASHAs, sub-centres, malaria clinics, CHCs, secondary/tertiary hospitals
- ABER (Annual Blood Examination Rate): Maintained at ~10% nationally; much higher in high-endemic areas
- About 100 million blood slides collected from fever cases annually; ~1.5 million malaria cases detected
- RDTs deployed at ASHA level for point-of-care diagnosis
- Programme plans to supply RDT kits to private providers in exchange for data
Special Strategy for P. vivax Elimination
India accounts for > 50% of estimated global P. vivax cases. P. vivax elimination is especially challenging because:
- Hypnozoites prolong parasite lifespan and are difficult to detect
- RDTs for P. vivax are less sensitive than those for P. falciparum
- Radical treatment requires 14 days of primaquine (vs. only 3 days for P. falciparum ACT)
- P. vivax has a longer incubation period
Special measures for P. vivax elimination:
- Expanding bivalent RDTs and quality microscopy to detect all P. vivax infections
- Ensuring compliance with 14-day radical primaquine treatment
- Tackling urban malaria by targeting An. stephensi by antilarval measures
Focus on High-Endemic Areas and Tribal Population
Most malaria cases reported from: Andhra Pradesh, Chhattisgarh, Jharkhand, MP, Maharashtra, Meghalaya, Mizoram, Odisha, Telangana, and Tripura - particularly in tribal populations in foothills, forested, and conflict-affected areas.
The programme plans to scale up interventions in these areas with innovative strategies.
Key Indicators for Monitoring

| PFPR | P. falciparum Proportion Rate |
