Strategic Action Plan for Malaria Control in India

(From Park's Textbook of Preventive and Social Medicine)

Three-Pronged Strategy of NVBDCP

Under NVBDCP, the three-pronged strategy for prevention and control of vector-borne diseases is:
  1. Disease management - early case detection, complete treatment, strengthening referral services, epidemic preparedness and rapid response
  2. 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
  3. 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:
  1. Eliminate malaria (zero indigenous cases) throughout the entire country by 2030
  2. Maintain malaria-free status in areas where transmission has been interrupted and prevent re-introduction

Time-Bound Objectives

Target YearObjective
2022Transmission interrupted and zero indigenous cases in all 26 States/UTs (Categories 1 and 2 as of 2014)
2024Incidence reduced to < 1 case per 1000 population in all States/UTs and their districts
2027Indigenous transmission interrupted in all States/UTs of India
2030Malaria 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:
CategoryDefinitionNo. of States/UTs
Category 0 - Prevention of re-establishmentStates with zero indigenous casesNone currently
Category 1 - Elimination phaseAPI < 1, all districts reporting API < 115 States/UTs
Category 2 - Pre-elimination phaseAPI < 1, but some districts reporting API ≥ 111 States
Category 3 - Intensified control phaseAPI ≥ 110 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:
  1. Zero cases
  2. API > 0 to < 1
  3. API 1 to < 2
  4. API 2 to < 5
  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

  1. Early diagnosis and radical treatment
  2. Case-based surveillance and rapid response
  3. Integrated Vector Management (IVM):
    • Indoor Residual Spray (IRS)
    • Long-Lasting Insecticidal Nets (LLINs) / ITNs
    • Larval Source Management (LSM)
  4. Epidemic preparedness and early response
  5. Monitoring and evaluation
  6. Advocacy, coordination and partnerships
  7. Behaviour Change Communication (BCC) and community mobilization
  8. Programme planning and management

Category-Specific Interventions

Category 3 - Intensified Control Phase (API ≥ 1)

  1. Massive scaling up of disease management and preventive approaches
  2. Screening of all fever cases suspected for malaria
  3. Classification of areas by local malaria epidemiology; tailored interventions
  4. Strengthening intersectoral collaboration; special interventions for tribal populations and hard-to-reach/conflict-affected areas
  5. One-stop centres or mobile clinics on fixed days in tribal areas for malaria diagnosis and treatment
  6. Timely referral and treatment of severe malaria to reduce mortality
  7. Strengthening district/sub-district hospitals as per Indian Public Health Standards for severe malaria management
  8. Robust supply chain management system
  9. Optimum surveillance using microscopy and RDTs
  10. 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)

  1. All efforts directed at interrupting local transmission in all active foci
  2. Mandatory notification of each malaria case from private sector and all other health facilities
  3. Adequate case-based surveillance and complete case management
  4. Investigation and classification of all malaria foci
  5. Total coverage of all active foci by effective vector control measures
  6. Early detection and treatment using Active Case Detection (ACD) and Passive Case Detection (PCD)
  7. State and national level malaria elimination database established
  8. Interventions for mobile and migrant populations screening
  9. Effective epidemic forecasting and response system
  10. Quality assurance of all medicines and diagnostics
  11. 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

  1. Detect any re-introduced case
  2. Immediately notify all detected cases
  3. Determine causes of resumed local transmission
  4. Apply rapid curative and preventive measures
  5. Prevent re-introduction of malaria
  6. 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:
  1. Hypnozoites prolong parasite lifespan and are difficult to detect
  2. RDTs for P. vivax are less sensitive than those for P. falciparum
  3. Radical treatment requires 14 days of primaquine (vs. only 3 days for P. falciparum ACT)
  4. 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.
