Human strain of the virus found in South American monkeys
WASHINGTON — Scientists usually worry that animal diseases could spill over into humans. But “spillback” of Zika virus into monkeys in South America could be just as dangerous.
In areas where Zika infections are prevalent among humans and mosquitoes are abundant, the virus may be transmitted to wild primates, disease ecologist Barbara Han said February 6 at the American Society for Microbiology Biothreats meeting. If the disease gets established in monkeys or other wild primates, the animals may serve as reservoirs for future human outbreaks. That could make it nearly impossible to get rid of the virus, said Han, of the Cary Institute of Ecosystem Studies in Millbrook, N.Y.
Han and colleagues calculated the risk of Zika entering South American primate populations using criteria that include species range, body size and diet.
