Global convergence of emerging infectious diseases: Only a plane ride away
ON APRIL 18, 1947, a rhesus monkey being studied for yellow fever research in Uganda's Zika Forest became ill with a fever of 103° F (39.44° C). Scientists took blood samples and conducted tests. Rhesus monkey #766 had been stricken by something unknown. In time, the emerging virus would be named after the place where it was first discovered. In early 1948, scientists also isolated the Zika virus from Aedes africanus mosquitoes trapped in the same forest. Even though the Zika virus would generate only sporadic and limited scientific attention in the next few decades, a new microbial threat to human health had emerged.
