Malaria is a major health concern in the developing world including India. Overdiagnosis and overprescribing of malaria may lead to increase morbidity, mortality and increases risk of resistance to antimalarial drugs and hence increase the economical burden to health care system. The present study was carried out to determine the actual cases of malaria and extent of chloroquine resistance at Civil Hospital Ahmedabad, a tertiary care teaching hospital in Gujarat, India. After Institutional Ethics Committee approval, adult patients of either gender, presenting with a history of fever at the Out Patient Department (OPD), diagnosed to be suffering from malaria and prescribed chloroquine were included in the study. Peripheral thick blood smear test and OptiMAL-rapid diagnostic test (RDT) were carried out. RDT was performed in these patients on day 0 before the start of chloroquine treatment and after completion of the 3 day chloroquine treatment. They were again subjected to RDT on day 4. The positive cases on RDTon day 4 were considered as resistant to chloroquine. During the study period of 12 months, out of the 250 clinically suspected cases of malaria who were prescribed chloroquine, 80 (31%) cases (35 cases of P. vivax and the 45 of P. falciparum ) were positive for malaria (by the peripheral smear and the Rapid Diagnostic Test (RDT) OptiMAL test). Thirty out of the 35 cases of P. vivax malaria, responded to the three- day chloroquine treatment. Out of the 45 cases of P. falciparum malaria, 30 responded to chloroquine while 15 patients (35%) continued to be OptiMAL positive on 4th day and required change of treatment. It suggests that an early diagnosis, definitive treatment and avoiding overprescribing could delay drug resistance and reduce the morbidity and mortality due the disease.
