Comparative Role of Aedes albopictus and Aedes aegypti in the Emergence of Dengue and Chikungunya in Central Africa
Since its discovery in Nigeria in 1991, Aedes albopictus has invaded much of Central Africa, a region where Ae. aegypti also occurs. To assess the relationship between the invasion by Ae. albopictus and the recent emergence of dengue virus (DENV) and chikungunya virus (CHIKV), we undertook vector co...

Aedes albopictus
has invaded much of Central Africa, a region where
Ae. aegypti
also occurs. To assess the relationship between the invasion by
Ae. albopictus
and the recent emergence of dengue virus (DENV) and chikungunya virus (CHIKV), we undertook vector competence experiments on populations collected from Cameroon and conducted field investigations during concurrent epidemics of DENV and CHIKV in Gabon. Overall, infection and dissemination rates were not significantly different between
Ae. albopictus
and
Ae. aegypti
when exposed to titers of 10
8.1
mosquito infectious dose 50/mL and 10
7.5
plaque forming units/mL of DENV type 2 and CHIKV, respectively. Field investigations showed that
Ae. albopictus
readily bit man, was abundant, and outnumbered
Ae. aegypti
to a large extent in Gabon, particularly in suburban environments. Nevertheless,
Ae. aegypti
was predominant in the more urbanized central parts of Libreville. In this city, CHIKV and DENV were detected only in
Ae. albopictus
. These data strongly suggest that
Ae. albopictus
acted as the major vector of both viruses in Libreville in 2007, impacting on the epidemiology of DENV and CHIKV in this area. |
