Abstract

Aedes albopictus, a mosquito native to Asia, has invaded all five continents during the past three decades. It was reported in central Africa in the 2000s, first in Cameroon, and, since then, has colonised almost all countries of the region. The species, originally considered a secondary vector of dengue viruses, has been showed to play a major role in transmission of chikungunya virus in numerous countries, including in the central African region. We review the current spread of Ae. albopictus in central Africa, its larval ecology and its impact on indigenous species such as Ae. aegypti. We explore the potential of Ae. albopictus to affect the epidemiology of emerging or re-emerging arboviruses and discuss the conventional means for its control, while emphasizing the importance of data on its susceptibility to insecticides to cope with potential outbreaks.

Highlights

During the past three decades, Aedes albopictus (Skuse, 1894), an invasive species originating in Asia, has invaded the Americas, Europe and Africa [1,2]
Several arboviruses have been isolated from mosquitoes and human samples in central Africa [11,12,13,14], but no massive outbreak has been reported before introduction of the new competent vector Ae. albopictus
The introduction in central Africa of a new vector that is known to be competent for more than 20 arboviruses is a public health problem, because three arboviruses (CHIKV, dengue virus (DENV) and Zika virus (ZIKV)) that are endemic in the region have re-emerged

Several arboviruses have been isolated from mosquitoes and human samples in central Africa [11,12,13,14], but no massive outbreak has been reported before introduction of the new competent vector Ae. albopictus.
