nated from wild nonhuman primate and rodent species, including baboon, chimpanzee, mangabey, guenon, green monkey, cane rat, and rat. Pathogen screening identified retroviruses (4 SFV strains), herpesviruses (cytomegalovirus and lymphocryptovirus), or both in 12 nonhuman primate tissue samples. “Because most emerging infectious diseases of humans are originating in animals, it is of concern that even in this small number of samples from a limited number of animal species, it was possible to identify retroviruses and herpesviruses of potential concern for human populations,” said Gerald Keusch, MD, who was not involved with the research. Keusch, a professor of medicine and international health at Boston University, cochaired the 2009 surveillance and response report with Pappaioanou. None of the samples contained SIV or STLV, which have adapted to humans and spread as HIV and human T-lymphotropic virus (which is capable of causing leukemia, lymphoma, and neurologic disease), respectively; however, SIV and STLV are often present in specimens at bushmeat markets and in hunted nonhuman primates. None of the rodent samples carried viruses: all were negative for leptospira, anthrax, herpesviruses, filoviruses, paramyxoviruses, coronaviruses, flaviviruses, and orthopoxviruses. Broader surveillance is needed to expand the study’s findings, which only begin to paint a picture of the potential risks of imported wildlife products and do not address live wildlife. “We need more and smarter surveillance of the wildlife trade, more control over what is being transported across national boundaries, more and stricter law enforcement measures to stop individuals involved in the business, and better and more meaningful ways to inform the public about the inherent dangers in a believable manner,” said Keusch. “In terms of global spread of infectious diseases, wildlife may be the mosquitoes of the 21st century: effective, elusive, and damned hard to stop.”
