In 1989-91, post-monsoon epidemics of vivax malaria occurred in the central flood plain near Dhaka. Anopheles philippinensis, the usual vector in the paddy field habitat, was not present, but 1.4% of parous An. aconitus were infective. This is only the second time An. aconitus has been incriminated as a vector in Bangladesh. We speculate that the surprising(More)
Seasonal, holoendemic malaria transmission in a small, isolated forest community was studied by doing outdoor and indoor all-night man-biting catches over 21 consecutive months. More than 3.8% of Anopheles dirus (=An. balabacensis s.l.), the most frequently caught anopheline, were infective. One An. annularis was also infective. Transmission occurred only(More)
Integrated vector management is a pillar of the South Asian visceral leishmaniasis (VL) elimination program, but the best approach remains a matter of debate. Sand fly seasonality was determined in 40 houses sampled monthly. The impact of interventions on Phlebotomus argentipes density was tested from 2006-2007 in a cluster-randomized trial with four arms:(More)
Background. We field tested and validated a newly developed monitoring and evaluation (M&E) toolkit for indoor residual spraying to be used by the supervisors at different levels of the national kala-azar elimination programs in Bangladesh, India and Nepal. Methods. Methods included document analysis, in-depth interviews, direct observation of spraying(More)
OBJECTIVE To analyse the feasibility, acceptability and effectiveness of insecticide-treated bed nets with slow-release insecticides (KO Tab 123) as an option for kala-azar vector management in Bangladesh. METHODS Intervention study involving an insecticide dipping programme through village health workers supervised by public health officers covering 6967(More)
Malaria in the eastern forests of Bangladesh has never been controlled and has been the major source of the country-wide resurgence that has occurred since 1971. The malaria status of an isolated, forest-dwelling community was studied for 21 consecutive months. Blood examination, indirect hemagglutination testing, and detailed histories were used. Nearly(More)
In countries where malaria is endemic, routine blood slide examinations remain the major source of data for the public health surveillance system. This approach has become inadequate, however, as the public health emphasis has changed from surveillance of laboratory-confirmed malaria infections to the early detection and treatment of the disease.
