India is pursuing malaria-free status by 2030, a goal supported by strategic planning and significant progress. The nation has drastically reduced malaria cases from millions annually. Key guiding frameworks include the National Framework for Malaria Elimination (NFME) 2016-2030 and the National Strategic Plan for Malaria Elimination (2023-2027). India’s intermediate target is zero indigenous malaria cases by 2027.
Progress and Achievements in India’s Malaria Elimination 2030 Initiative
India has achieved substantial reductions in malaria incidence and mortality.
- 2017-2023: Estimated 93% decline in malaria cases and 68% drop in deaths.
- 2015-2023: Reported cases fell by nearly 80% (from ~1.17 million to 227,000); deaths fell from 384 to 83.
- 2024: India exited the World Health Organization’s (WHO) High Burden to High Impact (HBHI) group.
- Surveillance: Strengthened systems include improved Annual Blood Examination Rate (ABER) and the Integrated Health Information Platform (IHIP) for near real-time reporting.
- 2024 Status: 92% of districts reported an Annual Parasite Incidence (API) below 1, indicating a transition to the pre-elimination phase.
- Regional Impact (as of 2023):
- Category 0 States/UTs (Zero indigenous cases): Ladakh, Lakshadweep, Puducherry.
- Category 1 States/UTs (API < 1 per 1,000 population): 24 states and Union Territories (up from 15 in 2015).
- Category 2 States: Odisha, Chhattisgarh, Jharkhand, Meghalaya have shown sustained declines.
- District Achievements: 122 districts reported zero malaria cases in 2023.
Challenges persist in hard-to-reach, forested, tribal, and border areas.
Navigating the Hurdles: Challenges to India’s Malaria Elimination Goals
Despite progress, several complex challenges remain:
- Inadequate Surveillance and Data Management: Fragmented, often paper-based systems hinder real-time insights and rapid response.
- High Burden of *Plasmodium vivax* Malaria: Relapses due to dormant liver stages (hypnozoites), poor patient compliance with primaquine treatment, and monitoring difficulties.
- Accessibility and Healthcare Infrastructure: Limited facilities, scarce diagnostics, and inaccessible timely treatment in tribal, mountainous, and remote areas.
- Human Resources Shortages: Lack of skilled personnel (especially entomologists) and de-prioritization of malaria programs.
- Vector Control Challenges and Resistance: Emergence of drug-resistant parasites and insecticide resistance in mosquito vectors. Presence of multiple vectors, including invasive *Anopheles stephensi*, and challenges with outdoor transmission and changing vector behaviors.
- Population Movement and Cross-border Transmission: Internal migration and movement from neighboring endemic countries (Myanmar, Bangladesh) risk reintroduction.
- Diagnostic Limitations: Current tools may miss low-density and asymptomatic cases, allowing silent transmission.
- Private Sector Engagement Gaps: Inconsistent reporting and insufficient engagement from the private healthcare sector.
- Funding and Investment: Sustained and increased investment from public, private, and international sectors is vital.
Multi-pronged Strategies for India’s Malaria Elimination
India’s strategy, guided by the NFME and NSP, systematically dismantles transmission pathways:
1. Integrated Vector Management (IVM):
- Indoor Residual Spraying (IRS): Insecticide spraying on interior walls, targeted for high-risk areas and focal spraying around cases.
- Long-Lasting Insecticidal Nets (LLINs): Strategic distribution, especially in high-burden regions.
- Larval Source Management: Environmental management and biological control (e.g., larvivorous fish) to eliminate breeding sites.
- Targeted Vector Management: Focus on invasive species like *Anopheles stephensi* and research into insecticide resistance.
2. Case Management:
- Early Diagnosis: Rapid diagnostic tests (RDTs) and microscopy at village and primary healthcare levels.
- Prompt and Complete Treatment: Artemisinin-based Combination Therapy (ACT) for *P. falciparum*. Drug Distribution Centers (DDCs) and Fever Treatment Depots (FTDs) for rural access. Tafenoquine with G6PD diagnostics for *P. vivax*.
- Comprehensive Case Management Programs (CCMP): Piloted in states like Odisha for intensified surveillance, diagnosis, and treatment, including mass screening in inaccessible areas.
3. Strengthening Surveillance:
- Integrated Health Information Platform (IHIP): Digital platform for near real-time, case-based reporting.
- Active Surveillance: Intensified in high-risk zones (tribal, forested, border areas) and among migratory populations.
- Annual Blood Examination Rate (ABER): Continuous improvement in surveillance reach and diagnostic coverage.
- Diagnostic Capacity Building: National Reference Laboratories (NRLs) ensure accuracy and reliability.

Global Partnerships and Domestic Investment Fueling India’s Malaria Elimination
Achieving elimination goals relies on domestic investment and international collaborations.
Key International Collaborations and Funding Sources:
- The Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM):
- Invested over $2 billion in India since 2005.
- Allocated ~$200 million specifically for malaria programs.
- Funded ~80% (40 million) of LLINs distributed in India between 2016-2018.
- Fills resource gaps for anti-malarials, health systems strengthening, and marginalized populations.
- World Health Organization (WHO):
- Provides technical support, aligning strategies with global best practices (Global Technical Strategy for Malaria 2016–2030).
- Supported development of the National Strategic Plan for Malaria Elimination (2023-2027).
- Other International Agencies: World Bank, Bill & Melinda Gates Foundation contribute resources and expertise. Malaria No More India advocates for diverse donor investments.
- Regional Networks: Active participation in APMEN and APLMA for best practice exchange and accelerated regional progress.
Domestic Funding and Investment Needs:
- Domestic funding constitutes over three-quarters of total malaria program resources (e.g., >75% of US$300 million between 2017-2019).
- Estimated need of over Rs 10,000 crore (~$1.2 billion USD) until 2022.
- Government’s increasing health allocations demonstrate commitment to meeting financial requirements.
Conclusion
India’s commitment to malaria elimination by 2030 is driven by its public health infrastructure, strategic planning, and collaboration. Significant progress, including reduced cases/deaths and exit from the WHO HBHI group, is evident. Challenges in surveillance, *P. vivax* management, and remote access persist, but multi-pronged strategies (IVM, case management, surveillance, community engagement) are in place. Increased domestic investment and international partnerships are crucial. India is advancing towards its 2027 target of zero indigenous cases, aiming for a malaria-free future through the collective dedication of all stakeholders.
