Current Zika transmission

 
Page last updated on 13 April 2017   
 

Information on the level of Zika transmission is useful for public health professionals to evaluate the level of risk for people who may be planning to travel to or are recently returning from areas with possible local transmission.   

A revised scheme has been developed by WHO, in collaboration with the US CDC and ECDC, to categorise the epidemiological profile of vector-borne Zika virus transmission in countries and territories. The classification can be applied at the national level as well as subnational level when the necessary information is available. ECDC has adapted the classification scheme to reflect the risk to travellers more accurately. It replaces the previous ECDC classification and the WHO interim guidance on Zika virus surveillance published in April 2016.

The information is updated at least once a month. It is also updated each time a new country reports local vector-borne Zika virus transmission. 

For a summary description of the revised scheme and a description of the ECDC adaptation see the updated ECDC rapid risk assessment. For the full description of the WHO categories, see the Zika virus country classification scheme, Interim guidance, March 2017.
