First confirmed occurrence of the yellow fever virus and dengue virus vector Aedes (Stegomyia) luteocephalus (Newstead, 1907) in Mozambique

Abstract: Background Mozambique, same as many other tropical countries, is at high risk of arthropod-borne virus (arbovirus) diseases and recently two dengue virus (DENV) outbreaks occurred in the northern part of the country. The occurrence of some important vector species, such as Aedes (Stegomyia) aegypti (Linnaeus) and Ae. (Stg.) albopictus (Skuse), besides several other sylvatic vectors, have been reported in the country, which may indicate that the transmission of some arboviruses of public health importance may i… Show more

“…1.5m above the ground, and were protected from the weather, theft, animals and/or children by available objects in the environment (mostly trees, or tall vegetation). Due to suspicion of arboviral diseases transmission in Mozambique, which has since been confirmed [ 33 , 34 ], no comparison against Human Landing Catches (HLC), the current gold standard methodology to assess human biting rates, were performed. As such, ‘exposure to hosts-seeking mosquitoes’ is reported throughout this study, rather than ‘vector bites’.…”

“…The HBTT utilized in this study demonstrates the adaptive implementation of a sampling tool based on local circumstances towards answering a specific question. The presence of Aedes aegypti and Aedes albopictus [ 23 , 47 ] associated with outbreaks of Dengue virus in Mozambique [ 48 ], resulted in the risk-assessment based termination of HLC, considered the gold standard in vector surveillance. Though the HBTTs functioned well to capture Anopheles , there remains the inability to directly compare them to HLCs in order to understand true landing rates.…”

“…’ the number of indoor and outdoor feeding mosquitoes (collected through the HBTT, presented as the mean number of biting mosquitoes per person) is estimated for each geography (district), season (rainy versus dry) and Anopheles species. Due to arboviral diseases transmission in Mozambique [ 23 , 24 ], no comparison against human landing catches (HLC), the current gold standard methodology to assess human biting rates, was performed. Hence, HBTT collections are taken as a proxy for HLC (or biting).…”

“…The outdoor traps were placed in the safest possible outdoor environment: under a tree close to the house, but away from animals and children. Due to suspicion of arboviral disease transmission in Mozambique, which was later confirmed [17,18], no comparisons against human landing catches (HLC) were done. Hence, we discuss here exposure to host-seeking mosquitoes rather than providing human biting rates.…”
