In a vulnerable forest in southeastern Brazil, where the air was once thick with the guttural chatter of brown howler monkeys, there now exists silence.

Yellow fever, a virus carried by mosquitoes and endemic to Africa and South America, has robbed the private, federally-protected reserve of its brown howlers in an unprecedented wave of death that has swept through the region since late 2016, killing thousands of monkeys.

Karen Strier, a University of Wisconsin-Madison professor of anthropology, has studied the monkeys of this forest since 1983. She visited the reserve -- her long-term study site near the city of Caratinga -- in the state of Minas Gerais, in January of 2017. "It was just silence, a sense of emptiness," she says. "It was like the energy was sucked out of the universe."

Using what in some cases are decades of historical data, Strier and a team of Brazilian scientists focused on studying primates in Brazil's patchwork Atlantic Forest are poised to help understand and manage what happens next. They have never seen monkeys perish in such numbers, so quickly, from disease.

[...] The way yellow fever has spread also concerns Brazilian health officials. As of mid-March 2017, they have confirmed more than 400 human cases of the disease, mostly in Minas Gerais, causing nearly 150 human deaths. The Brazilian Ministry of Health is investigating another 900 possible cases and concern is mounting that it will spread to cities, threatening many more people.
