Rapid risk assessment: Microcephaly in Brazil potentially linked to the Zika virus epidemic, 25 November 2015
The increase in congenital microcephaly observed in Brazil is of concern. Its emergence a few months after the introduction of Zika virus (ZIKV) infection into the country raises questions about the possible role of the infection in congenital microcephaly.
There is currently only ecological evidence of an association between the two events. A possible causative nature of the association cannot be ruled out with the evidence available. Further investigations and studies will contribute to a better characterisation of the association, and provide a better understanding of the possible role of other prenatal infections, genetic risk factors, environmental exposure to chemicals or consumption of of teratogenic drugs. Studies of the ZIKV genome will provide information on possible changes that might influence ZIKV disease characteristics and vector competence.

Rapid risk assessment: Zika virus disease epidemic, eighth update
This eighth update assesses the risks associated with the Zika virus epidemic currently affecting countries in the Americas. It provides updated information for those travelling to and returning from affected countries and for EU citizens residing in areas with active transmission. It reviews available information on the association between Zika virus infection and congenital central nervous system malformations, including microcephaly, as well as the association between Zika virus infection and Guillain–Barré syndrome. It also proposes a range of mitigation measures for EU/EEA Member States to consider.Read more
