Nkhuku, abakha, atsekwe ndi mallards amatha kudwala matendawa, ndipo kutengeka kwa nkhuku zosiyanasiyana ku matenda oikira mazira kumasiyanasiyana, ndi nkhuku zoikira zipolopolo za bulauni zomwe zimagwidwa kwambiri. Matendawa amakhudza kwambiri nkhuku zapakati pa masabata 26 ndi 32 zakubadwa, ndipo samapezeka kwambiri pakadutsa milungu 35 yakubadwa. Nkhuku zazing'ono siziwonetsa zizindikiro pambuyo pa matenda, ndipo palibe antibody yomwe imapezeka mu seramu, zomwe zimakhala zabwino pambuyo poyambira kupanga mazira. Magwero a kachilombo ka HIV ndi nkhuku zomwe zili ndi matenda komanso nkhuku zomwe zimanyamula tizilombo toyambitsa matenda, anapiye omwe ali ndi kachilombo, komanso kukhudzana ndi ndowe ndi ukazi wa nkhuku zomwe zili ndi matenda. Nkhuku kachilombo alibe zizindikiro zoonekeratu matenda, 26 kwa 32 milungu kuikira nkhuku dzira kupanga mlingo mwadzidzidzi anatsika 20% mpaka 30%, kapena 50%, ndi mazira woonda-zipolopolo, mazira zofewa-zipolopolo, mazira popanda chipolopolo, mazira ang'onoang'ono, chigoba cha mazira pamwamba aukali kapena dzira mapeto anali granular (sandpaper-ngati), dzira loyera lachikaso losakanikirana ndi madzi akunja, dzira loyera lachikaso, dzira loyera lachikaso, dzira loyera lachikaso, dzira loyera lachikaso. Kuchuluka kwa umuna ndi kuswa mazira omwe amaikira ndi nkhuku zodwala nthawi zambiri sakhudzidwa, ndipo chiwerengero cha anapiye ofooka chikhoza kuwonjezeka. Matendawa amatha masabata 4 mpaka 10, kenako kuchuluka kwa mazira a ziweto kumatha kubwerera mwakale. Nkhuku zina zodwala zimathanso kuwonetsa zizindikiro monga kusowa mzimu, kolona woyera, nthenga zophwanyika, kusafuna kudya komanso kamwazi.

Pokumbukira kukhazikitsidwa kwa oweta ochokera kumadera omwe alibe kachilomboka, zoweta zoyambilira ziyenera kukhala paokha ndikusungidwa kwaokha, ndipo kuyesa kwa hemagglutination inhibition test (HI test) kuyenera kugwiritsidwa ntchito atayikira mazira, ndipo okhawo omwe ali ndi kachilombo ka HIV ndi omwe angasungidwe kuti abereke.
