Abstract | Background
Chikungunya virus (CHIKV), mainly transmitted in urban areas by the mosquitoes Aedes
aegypti and Aedes albopictus, constitutes a major public health problem. In late 2013,
CHIKV emerged on Saint-Martin Island in the Caribbean and spread throughout the region
reaching more than 40 countries. Thus far, Ae. aegypti mosquitoes have been implicated as
the sole vector in the outbreaks, leading to the hypothesis that CHIKV spread could be limited
only to regions where this mosquito species is dominant.Methodology/Principal Findings
We determined the ability of local populations of Ae. aegypti and Ae. albopictus from the
Americas and Europe to transmit the CHIKV strain of the Asian genotype isolated from
Saint-Martin Island (CHIKV_SM) during the recent epidemic, and an East-Central-South African
(ECSA) genotype CHIKV strain isolated from La Réunion Island (CHIKV_LR) as a
well-characterized control virus. We also evaluated the effect of temperature on transmission
of CHIKV_SM by European Ae. albopictus.We found that (i) Aedes aegypti from Saint-Martin Island transmit CHIKV_SM and CHIKV_LR with similar efficiency, (ii) Ae. aegypti
from the Americas display similar transmission efficiency for CHIKV_SM, (iii) American and
European populations of the alternative vector species Ae. albopictus were as competent
as Ae. aegypti populations with respect to transmission of CHIKV_SM and (iv) exposure of
European Ae. albopictus to low temperatures (20°C) significantly reduced the transmission
potential for CHIKV_SM.Conclusions/Significance
CHIKV strains belonging to the ECSA genotype could also have initiated local transmission
in the new world. Additionally, the ongoing CHIKV outbreak in the Americas could potentially
spread throughout Ae. aegypti- and Ae. albopictus-infested regions of the Americas with
possible imported cases of CHIKV to Ae. albopictus-infested regions in Europe. Colder temperatures
may decrease the local transmission of CHIKV_SM by European Ae. albopictus,
potentially explaining the lack of autochthonous transmission of CHIKV_SM in Europe despite
the hundreds of imported CHIKV cases returning from the Caribbean. | pt_BR |
