Basic considerations in assessing and preventing occupational infections in personnel working with nonhuman primates

Transmission of zoonotic infections of nonhuman primates to human contacts is a documented occupational hazard. Although the list of naturally occurring and experimentally induced infections of nonhuman primates is extensive the risks of transmission may substantially be reduced by the use of good animal care practices, appropriate protective measures and devices, and suitable animal facilities. The essential elements of good animal care practices include high levels of personal hygiene; minimizing the creation of potentially infectious aerosols and droplets; use of personal protective clothing, devices, and vaccines; a system for reporting, evaluating, and treatment of occupational exposures and infections; and animal facilities appropriate for the species being used and the activities conducted. These essential elements are described and discussed in the context of published voluntary codes of practice--notably "Biosafety in Microbiological and Biomedical Laboratories."
