Zika Virus poses a specific threat to pregnant mothers, as the transmission of Zika Virus from mother to child can cause severe brain related birth defects. Babies with Zika Virus are often born with very small heads and brain defects (microcephaly). This is why pregnant women are specifically warned against travelling to countries where Zika is spreading.

Brazil Olympics Zika fears

With Zika Virus spreading across Brazil, there are serious fears about the upcoming Rio de Janeiro Olympics. Many athletes have decided not to go and important health authorities have warned against it.

As Amir Attaran wrote in the Harvard Public Health Review, “Clinical studies are also mounting that Zika infection is associated not just with pediatric microcephaly and brain damage, but also adult conditions such as Guillain-BarrĂ© syndrome[1] and acute disseminated encephalomyelitis, which are debilitating and sometimes fatal.[2]”

Attaran has called for the Brazil Olympics to be cancelled because of the Zika Virus, but the games are going ahead.

With Zika spreading further and further, health authorities must act quickly, or a severe public health disaster could follow.
