*Only the 85 persons with nown severe bites or scratches from a nonhuman primate. Univariate analyses were performed by using STATA (StataCorp LP, College Station, TX, USA) software with the χ2 and Fisher exact tests with critical p value = 0.05.
†Most pets were Cercopithecus nictitans and mandrills; some were small chimpanzees.
