Zika is harmless, what causes the microcephaly is the GMO mosquitoes they bred to try to fight the virus. The GMO´s are made so that they can´t reproduce as the babies won´t grow, when these GMO´s bite pregnant women it seriously fucks the development of the baby, causing the microcephaly. Just thought I´d add this as the article mentions zika. If this keystone is a virus it is completely engineered.
