Epidemiological update: Outbreaks of Zika virus and complications potentially linked to the Zika virus infection, 30 June 2016

​New developments since the last epidemiological update

 

During the past week, no new country or territory has reported mosquito-borne Zika virus transmission. In the USA, the Florida Department of Health confirmed the first Zika-related case of microcephaly in a child born in Florida whose mother had a travel-related case of Zika. The mother, a citizen of Haiti, came to Florida to deliver her baby.

EU/EEA and EU Outermost Regions and Territories

 

Since week 45/2015, ten countries (Belgium, Czech Republic, Denmark, Finland, France, Italy, Malta, Slovenia, Spain and the UK) reported 783 travel-associated Zika virus infections through The European Surveillance System.

As of 30 June 2016, ECDC has detected 929 imported cases through Epidemic Intelligence activities. This information is aggregated from official EU/EEA public health authorities websites but is not based on a systematic reporting surveillance system hence cannot be considered exhaustive.

As of 29 June 2016, microcephaly and other central nervous system (CNS) malformations associated with Zika virus infection or suggestive of congenital infection have been reported by thirteen countries or territories. In the EU, Spain (2) and Slovenia (1) reported congenital malformations associated with Zika virus infection after travel in the affected areas. Cases have also been detected in the EU’s Outermost Regions and Territories in Martinique, French Guiana and French Polynesia. Fourteen countries and territories worldwide reported an increased incidence of Guillain-Barré syndrome (GBS) and/or laboratory confirmation of a Zika virus infection among GBS cases.   Brazil: Between October 2015 and 30 June 2016, Brazil has reported 8 165 suspected cases of microcephaly and other nervous system disorders suggestive of congenital infection; this is an increase of 229 cases since the last update; 1 638 are confirmed cases of microcephaly, 270 of which are laboratory-confirmed for Zika virus infection.
