¹Exposure behavior is discrete variable 0:6; primates with higher SFV prevalence (black mangabey, agile mangabey, Wolf’s guenon, Angolan colobus, gorilla) each represent 1 species-exposure, whereas the other five species groups represent 1-species-exposure collectively.
²The odds ratio is interpreted as 1 greater species-exposure. The descriptive percentage and estimated prevalence rates reflect any exposure to 1 or more species.
³ ref, reference group in regression models.
⁴ NA, not applicable. Exposure variables were not included in regression models if there were no cases among persons identified as having the exposure.
⁵Brought dead animal excludes hunting NHPs.
