Zika virus - surveillance archive

Zika virus is transmitted to people through the bite of an infected mosquito from the Aedes genus, mainly Aedes aegypti, in tropical regions. While the symptoms of Zika are usually mild, WHO has concluded, based on the available evidence, that Zika virus infection during pregnancy is a cause of congenital brain abnormalities, including microcephaly; and that Zika virus is a trigger of Guillain-Barré syndrome. 

WHO’s response to Zika virus and its complications has now transitioned to a sustained programme to address the long-term nature of the disease and its consequences.
