Seroconversion to SIV - Continued
The frequency of exposures in SIV research laboratories and the risk of seroconversion in SIV laboratory and animal-care workers have not been well defined.
Approximately 200-300 persons are working with these agents in U.S. laboratories.
CDC has investigated two other persons with percutaneous exposures involving cuts
with scalpels during necropsies on SIV-infected animals. Neither have shown any
evidence of seroconversion up to 6 months after the incidents. CDC, in collaboration
with the National Institutes of Health, is conducting a serosurvey of workers in
federally funded SIV research facilities to estimate the prevalence of such seroreactivity in persons with potential exposure to SIV.
