Science: Zika has all but disappeared in the Americas. Why?
“…Zika cases have plummeted in Latin America and the Caribbean, where the virus raged over the past two years, and much of the population is now immune to it. That, in turn, means fewer infected people entering the United States, reducing the chances of mosquitoes spreading the virus to susceptible people. The respite, experts say, could last for years…” (Cohen, 8/16).
