Burden of asymptomatic malaria among a tribal population in a forested village of central India: a hidden challenge for malaria control in India

摘要

Objective: Chhattisgarh in India is a malaria-endemic state with seven southern districts that contributes approximately 50-60% of the reported malaria cases in the state every year. The problem is further complicated due to asymptomatic malaria cases which are largely responsible for persistent transmission. This study was undertaken in one of the forested villages of the Keshkal subdistrict in Kondagaon district to ascertain the proportion of the population harbouring subclinical malarial infections. Study design: Community-based cross-sectional study.
