Which statement best describes the drivers of malaria decline in India?

• A. Urban development alone reduced transmission
• B. National framework for malaria elimination, better management of disease
• C. Increased rainfall reduced malaria
• D. Vaccination campaigns eradicated malaria

Answer: (B)

A coordinated national program and improved management of malaria drive declines in transmission more than isolated factors. The National Framework for Malaria Elimination provides a comprehensive, data-driven approach that strengthens surveillance to quickly detect cases, ensures rapid diagnostic testing and prompt, effective treatment, and carries out targeted vector control in high-burden areas. When these elements work together, fewer people remain infectious, mosquito transmission is interrupted more efficiently, and overall incidence falls across diverse regions. Urban development can help in specific contexts but doesn’t fully explain a countrywide drop. Rainfall can influence transmission but isn’t a reliable driver of sustained decline. Vaccination campaigns have not eradicated malaria at scale in India. So, the national framework paired with better disease management best explains the observed decline.
