Invasive mosquito species threatens India’s 2030 malaria elimination goal, Pg12

Key Highlights:

• Urban malaria, driven by Anopheles stephensi, threatens India's 2030 malaria elimination goal.
• Asymptomatic infections, difficult terrain, and population movement continue to drive transmission.
• India aims for zero indigenous cases by 2027, aligning with the WHO's global strategy.
• Malaria cases in India have dropped from 11.7 lakh in 2015 to around 2.27 lakh in 2024.

Detailed Insights:

• Anopheles stephensi thrives in urban environments, breeding in artificial containers and transmitting Plasmodium falciparum and P. vivax parasites.
• Urban transmission challenges include container breeding, construction sites, high population density, and fragmented healthcare, requiring city-specific strategies.
• Malaria persists in limited pockets shaped by local ecological conditions, human mobility, and health-system access.
• Key challenges include inconsistent private-sector reporting, limited entomological capacity, and drug resistance.

Key Concepts Involved:

• Anopheles stephensi: An invasive mosquito species that thrives in urban environments and transmits malaria.
• Plasmodium falciparum/vivax: Parasites transmitted by mosquitoes that cause malaria in humans.
• Malaria Elimination: A targeted effort to reduce malaria transmission to zero within a defined geographic area.
