Transmitted by the Aedes aegypti mosquito, Zika virus usually causes mild flu-like symptoms (fever, headache, body aches).

But it can also be the cause of microcephaly in babies or neurological disorders such as Guillain-Barré syndrome, which can cause paralysis of limbs and respiratory impairment.

the microcephaly is a malformation characterized by the small size of the skull of the fetus. It can cause disability or death.

Brazil, with 1.5 million cases of Zika, has documented 907 cases of microcephaly since October 2015, four times the historical annual average.
