A group of Argentine scientists, including health experts from the Wildlife Conservation Society, have announced that yellow fever is the culprit in a 2007-2008 die-off of howler monkeys in northeastern Argentina, a finding that underscores the importance of paying attention to the health of wildlife and how the health of people and wild nature are so closely linked.
The paperappearing in a recent edition of the American Journal of Primatologyfocuses on yellow fever outbreaks that were documented in several howler monkey populations of Misiones Province, Argentina. The epidemics, which caused the death of dozens of rare howler monkeys, signaled the need for a human vaccination program in the region to save lives.
The authors of the study include: Ingrid Holzmann and Mario S. Di Bitetti of the Argentine Council for Science and Technology (CONICET); Ilaria Agostini of the Universidad de Roma and CNR; Juan Ignacio Areta of Grupo FALCO; and Hebe Ferreyra and Pablo Beldomenico of the Wildlife Conservation Society.
"The outbreak has tragic conservation implications for the endangered brown howler monkey, one of the two species affected, which is highly threatened primarily by habitat destruction, hunting, and now disease," said Dr. Pablo Beldomenico. "The study also points out the importance of wildlife as a critically important indicator of health and disease processes which can help protect people too."
The authors of the paper initiated their research as an ecological study of two howler monkey species of El Pialito Provincial Park in January 2005, a project that enabled them to detect the first occurrence of two yellow fever outbreaks between November 2007 and October 2008. After finding four of their study monkeys dead, the team of biologists, park rangers, and veterinarians organized a search both within and outside of the study area to gauge the extent of mortality. The role of yellow fever in the events was confir
