Update on microcephaly and/or central nervous system (CNS) malformations potentially associated with Zika virus infection

 

ECDC assessment

  • The spread of the Zika virus in the Americas 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.
  • A detailed risk assessment was published on 30 August 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.
