Distribution and breeding sites of Aedes aegypti and Aedes albopictus in 32 urban/peri-urban districts of Mozambique: implication for assessing the risk of arbovirus outbreaks

摘要: Background Aedes-borne arboviruses have emerged as an important public health problem worldwide and, in Mozambique, the number of cases and its geographical spread been growing. However, information on occurrence, distribution ecology Aedes aegypti Ae. albopictus mosquitoes remain poorly known country. Methods Between March April 2016, a cross-sectional study was conducted 32 districts Mozambique to determine breeding sites albopictus. Larvae pupae were collected from total 2,807 water-holding containers using pipette, dipper, funnel sweeping procedures, depending container type location. Both outdoor indoor inspected. The immature forms reared adults identifications mosquito species carried out with stereomicroscope taxonomic key. Results Aedes found every district sampled, while only Moatize district, situated Tete Province central part country. Six hundred twenty-eight (22.4%) positive for but one (0.03%) Container Index (CI) highest densely populated suburban areas region (260/604; 43.0%), followed by northern (228/617; 36.9%) whilst lowest proportion urbanized southern (140/1586; 8.8%). CI used tires (448/1268; 35.3%), cement tanks (20/62; 32.3%) drums (21/95; 22.1%). Conclusion Data our showed that is present nation-wide, since it occurred sampled had limited distribution. Therefore, risk transmission dengue chikungunya likely underestimated Mozambique. This highlights need establishment national entomological surveillance program spp. order gain better understanding about vector bionomics support development informed effective control strategies.
