Persistent transmission of malaria in Garo hills of Meghalaya bordering Bangladesh, north-east India
Abstract Background Malaria is endemic in Garo hills of Meghalaya, and death cases are reported annually. Plasmodium falciparum is the major parasite, and is solely responsible for each malaria-attributable death case. Garo hills are categorized high-risk for drug-resistant malaria; however, there e...
