Resumo: Objective To report dengue virus and its disease transmission in Aedes albopictus in the National Capital Territory of Delhi, India. Methods Monthly Aedes surveys were carried out in 126 urban localities of Delhi in 2008 and 2009. Pools of all three species of Aedes mosquitoes were tested for Dengue virus (DENV) using an antigen-capture enzyme-linked immunosorbent assay. ResultsAedes aegypti was the most prevalent species, breeding throughout the year. Aedes albopictus was found in 9.52% of surveyed localities including the central urban part of Delhi, in March and from August to October. Aedes albopictus and Aedes vittatus are adapting to breed in manmade containers in the urban areas of Delhi in addition to their natural habitats of bamboo bushes and rock pits. Of the 229 pools of Ae. aegypti and 34 pools of Ae. albopictus tested, 10.5% and 11.76% were positive for dengue virus, respectively. No dengue virus infection was recorded in Ae. vittatus. Conclusion This is the first report of dengue virus in Ae. albopictus from north India. Because DENV was detected in Ae. albopictus, which adapted to manmade containers, both its spread and transmission dynamics should be checked.Original Abstract: Objectif: Determiner le taux d'acceptation de l'autopsie et les raisons du refus a l'hopital de Mulago, Kampala, Ouganda. Methodes: Les proches de patients decedes dans un service combine de maladies infectieuses et de gastro-enterologie de l'hopital de Mulago ont ete contactes pour repondre a un questionnaire concernant les caracteristiques de leur parent decede. Au cours de l'entretien, leur consentement a ete demande afin d'effectuer une autopsie complete. Dans le cas d'un refus, les proches ont ete invites a donner leur raison. Resultats: L'autorisation de proceder a une autopsie a ete demandee pour 158 (54%) des 290 deces survenus pendant la periode d'etude. Dans 60 (38%) des cas, l'autopsie a ete acceptee. 59 autopsies ont ete pratiquees. Pour 82% des cas de refus un motif a ete repertoriee, principalement: > (16%) et > (10%). Conclusion: Le taux d'autopsies realisees dans les conditions de l'etude etait de 38% par rapport au taux de 5% dans l'hopital de Mulago au cours des dix dernieres annees. La demande en temps opportun et la realisation rapide des autopsies semblent etre des determinants importants de l'acceptation de l'autopsie. Une equipe de pathologistes et de cliniciens motives est necessaire pour accroitre l'acceptation de l'autopsie.
