The Zika virus is out of control. Earlier this week, the World Health Organization called it an “explosive” epidemic, and officials in Brazil, the country hardest hit by the disease, have admitted that they are “losing badly” to the disease. Brazilian president Dilma Rousseff went so far as to declare war on Aedes aegypti, the mosquito that transmits Zika. Officials in several other countries in the region have asked women to consider not getting pregnant until the epidemic is brought under control.
