*SFV, simian foamy virus; LTR, long terminal repeat; +, positive; –, negative; DBS, dried blood spot; NK, not known; Chimp., chimpanzee; ND, not determined; Cerco., Cercopithecus. The age at contact with nonhuman primate and the type of animal contact concern the results of the field interviews performed for each person found to be infected by SFV.
†Wife or husband also tested.
‡Retrospective study participant.
§1 (A051302) or 2 (CH61 and 801001) children also tested.
¶Hunter study participant.
