At this point, even extraterrestrials have probably heard that the World Health Organization declared the recent spread of the Zika virus an international public health emergency. That sounds pretty scary. It’s only the fourth time that the WHO has ever declared a PHEIC (Public Health Emergency of International Concern) so it seems like it ought to be a big deal.
However, it’s important to keep things in perspective. As of May 4, there were 1,278 confirmed cases of microcephaly, the birth defect linked to Zika virus infection that causes an abnormally small head and brain. There are approximately 250 suspected neonatal and fetal deaths. In comparison, the last PHEIC was the Ebola virus outbreak of 2014. The current total number of reported cases of Ebola is 28,616 causing 11,310 deaths. Finally, the WHO estimates that the annual run-of-the-mill flu season –not famous epidemics like the Swine Flu – causes 250,000 to 500,000 deaths every year around the world.
