Abundant <i>Aedes</i> (<i>Stegomyia</i>) <i>aegypti aegypti</i> mosquitoes in the 2014 dengue outbreak area of Mozambique

ABSTRACT

In early 2014, dengue cases werereported from the northern Mozambique, 30 years since the last outbreak. Weidentified potential dengue vector species in three northern towns, Pemba, Nampulaand Nacala, and one southern town, Maputo, during the outbreak in April 2014. Amajor dengue vector species, <i>Aedes</i> (<i>Stegomyia</i>) <i>aegypti</i>, wasfound in all these towns. The dominant vector subspecies in the northern townswas <i>Aedes aegypti aegypti</i>, while <i>Ae. aegyptiformosus </i>was dominant in Maputo. Considering the high proportions of <i>Ae. aegypti aegypti</i> and its high vectorcompetence, the findings from this study suggest that <i>Ae. aegypti aegypti</i> was responsible for the outbreakin the northern Mozambique.
