For a healthy grown-up who isn’t pregnant, Zika doesn’t pose much of a threat. Common symptoms include fever, joint ache and a rash with small red spots. The US Center for Disease Control and Prevention (CDC) puts it pretty clearly: “The illness is usually mild… Severe disease requiring hospitalization is uncommon. Deaths are rare.”Compare that to Ebola, which comes with vomiting and unexplained bleeding and killed more than 11,300 people in the recent West-Africa outbreak, and you’ll see that Zika isn’t quite that bad.Some tourists have already brought the virus back to their European home countries from vacation without any major consequences. According to the news agency Deutsche Presse-Agentur (dpa), there have been ten cases reported in Germany since 2013.The dpa also mentions four cases in Italy, three in Great Britain and two in Spain, though those numbers are probably incorrect, since there’s no international protocol for reporting and recording the virus, Schmidt-Chanasit said. More people could have been infected without ever knowing: the CDC reports that only one in five people infected with the virus actually become ill.Dangerous birth defect In hospitals like this one in Recife, Brazil, more and more babies are born with mircrocephalyAll that is not to say that Zika is completely harmless. The virus has been connected to an exceptional high number of babies born with microcephaly in Brazil. In the most recent Zika outbreak, around 4,000 newborns were diagnosed with the birth defect. Their skulls are smaller than those of healthy babies, which leads to brain damage.
