The Zika virus is transmitted by mosquitoes to infect humans. Since 2015, Central and South America and the Caribbean have suffered from a Zika epidemic of unprecedented scale. A Zika infection generally causes a mild disease, but unborn children can develop severe brain damage when their mothers get infected. Wageningen University & Research virologists and entomologists are studying the capacity of Dutch mosquito species to transmit the Zika virus. The results are important to determine the risk of Zika outbreaks in the Netherlands.
