Zika situation report – 28 April 2016
As of 27 April, 55 countries and territories report continuing mosquito-borne transmission; for 42 countries this is their first documented Zika virus outbreak
In the week to 27 April, no additional countries reported mosquito-borne Zika virus transmission. Canada is the latest country to report person-to-person transmission.
Microcephaly and other fetal malformations potentially associated with Zika virus infection or suggestive of congenital infection have been reported in six countries or territories (Table 3). Two cases, each linked to a stay in Brazil, were detected in Slovenia and the United States of America. One additional case, linked to a brief stay in Mexico, Guatemala and Belize, was detected in a pregnant woman in the United States of America.
In the context of Zika virus circulation, 13 countries and territories worldwide have reported an increased incidence of Guillain-Barré syndrome (GBS) and/or laboratory confirmation of a Zika virus infection among GBS cases.
Based on research to date, there is scientific consensus that Zika virus is a cause of microcephaly and GBS.
The global prevention and control strategy launched by the World Health Organization as a Strategic Response Framework encompasses surveillance, response activities and research.
