Abstract
Lessons learned on Zika virus vectors
Highlights
The most recent examples of disasters caused by mosquito-borne arboviruses are the 2015– 2016 re-emergences of urban yellow fever (YF) in Angola, which reached the Democratic Republic of Congo, with viremic people dispersing to densely populated regions in Asia, such as China [1], and the global emergence and spread of chikungunya and Zika viruses in the Pacific region and the Americas [2,3]
To appraise the likely role of a mosquito species in transmitting an arbovirus by assessing vector competence may help in determining the risk of arbovirus transmission and spread and, more importantly, in structuring efficient vector control by targeting the correct vector species
Mosquito-borne Zika virus (ZIKV) transmission has only been reported in Aedes (Stegomyia) infested territories, and Ae. (Stg.) aegypti has been considered its main vector across the world [3,4,5]
Summary
The most recent examples of disasters caused by mosquito-borne arboviruses are the 2015– 2016 re-emergences of urban yellow fever (YF) in Angola, which reached the Democratic Republic of Congo, with viremic people dispersing to densely populated regions in Asia, such as China [1], and the global emergence and spread of chikungunya and Zika viruses in the Pacific region and the Americas [2,3]. To appraise the likely role of a mosquito species in transmitting an arbovirus by assessing vector competence may help in determining the risk of arbovirus transmission and spread and, more importantly, in structuring efficient vector control by targeting the correct vector species. Sexual and other interhuman ZIKV contaminations have been confirmed, the primary route of viral transmission is accomplished through the bite of an infected Aedes mosquito.
