Zika virus and complications
WHO public health advice regarding the Olympics and Zika virus
28 May 2016 - Based on current assessment, cancelling or changing the location of the 2016 Olympics will not significantly alter the international spread of Zika virus. Brazil is one of almost 60 countries and territories which to-date report continuing transmission of Zika by mosquitoes. People continue to travel between these countries and territories for a variety of reasons. The best way to reduce risk of disease is to follow public health travel advice.
Zika virus outbreak global response
27 May 2016 – The newly launched "Zika virus outbreak global response: Interim report" provides an update on key activities, the funding gap, and the new strategy moving forward to guide the international response to the spread of Zika virus.
Zika virus strain imported from the Americas to Cabo Verde
20 May 2016 -- Sequencing of the virus in Cabo Verde by Institut Pasteur, Dakar confirms that the Zika virus currently circulating in Cabo Verde is the same as the one circulating in the Americas - the Asian type- and was most likely imported from Brazil. This is the first time that the Zika strain responsible for the outbreaks linked to neurological disorders and microcephaly has been detected in Africa.
One year into the Zika outbreak
5 May 2015 -- On 7 May 2015, Brazil informed WHO/PAHO of its first laboratory confirmed cases of Zika virus. In the last year the scientific community has learned an extraordinary amount about this virus and its effects.
WHO continues to lead the research agenda, while supporting countries in the response. This article chronicles Zika virus from when it was first identified, and details how this fairly obscure disease became a global health emergency.

Zika virus timeline
This timeline summarizes the spread of Zika infection, country by country, from the earliest discovery in 1947 to the latest information as of 7 February 2016. Zika virus infection appears to have changed in character while expanding its geographical range.
