Epidemiological situation

This page was last updated on 27 January 2017

Weekly summary

Dominica and Trinidad and Tobago have been removed from the map of countries and territories with autochthonous vector-borne transmission of Zika virus infection in the past three months.
 
On 26 January 2017, the Regional Office for the Americas of the World Health Organization reported new municipalities at risk for yellow fever transmission in Bahia, Espirito Santo and Rio de Janeiro states.

 

Epidemiological summary

Worldwide
Since 2015 and as of 27 January 2017, 72 countries and territories have reported evidence of mosquito-borne transmission of the virus. Since February 2016 and as of 18 January 2017, 13 countries or territories have reported evidence of person-to-person transmission of the virus, probably via sexual transmission.
 
EU/EEA imported cases 
Since June 2015 (week 26), 21 countries (Austria, Belgium, the Czech Republic, Denmark, Finland, France, Greece, Hungary, Ireland, Italy, Luxembourg, Malta, the Netherlands, Norway, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and the United Kingdom) have reported 2 081 travel-associated Zika virus infections through The European Surveillance System (TESSy). Over the same time period, nine EU/EEA Member States have reported 103 Zika cases among pregnant women.
 
Update on microcephaly and/or central nervous system malformations potentially associated with Zika virus infection
According to WHO and as of 18 January 2017, 29 countries or territories have reported microcephaly and other central nervous system malformations in newborns which are potentially associated with Zika virus infection. Brazil is reporting the highest number of cases. Twenty-one countries or territories have reported Guillain-Barré syndrome potentially associated with Zika virus infection.
 

 

ECDC assessment

The spread of the Zika virus in the Americas and Asia is likely to continue as the vectors (Aedes aegypti and Aedes albopictus mosquitoes) are widely distributed there. The likelihood of travel-related cases in the EU is increasing. ECDC is preparing an update of the risk assessment published on 28 October 2016. As neither treatment nor vaccines are available, prevention is based on personal protection measures. Pregnant women should consider postponing non-essential travel to Zika-affected areas.
