In the Americas, primate species likely to harbor Zika -- and potentially transmit the virus -- are common, abundant, and often live near people. So reports a new study published today in Epidemics. Findings are based on an innovative model developed by a collaborative team of researchers from Cary Institute of Ecosystem Studies and IBM Research through its Science for Social Good initiative.

Lead author Barbara Han, a disease ecologist at Cary Institute, explains: "When modeling disease systems, data gaps can undermine our ability to predict where people are at risk. Globally, only two primate species have been confirmed positive for Zika virus. We were interested in how a marriage of two modeling techniques could help us overcome limited data on primate biology and ecology -- with the goal of identifying surveillance priorities."

The recent Zika epidemic in the Americas was one of the largest outbreaks in modern times, infecting over half a million people. Like other mosquito-borne flaviviruses, Zika circulates in the wild. Primates can serve as disease reservoirs of spillover infection in regions where mosquitoes feed on both primates and people.
