Izvozvo zvichangoitika, vakawana kuti vanhu vane chirwere ichi kazhinji vasangana uye vaya vakambotadza aita kuwedzerwa ropa kana zvinodhaka. Zvino mangwanani eighties remakore rechi20, masayendisiti American Robert Gallo uye M. zimbabwe pakutanga akataura kuti zvose nyaya rutapudzo of zvirwere, havasi rinorapika, migumisiro yacho chirwere. Mukuona kwavo, chirwere ichi anokonzerwa rudzi retrovirus unounza utachiona munhu mumwe mhando neleukemia.

Studies kuti vave inoitwa akazoratidza kuti AIDS ikabuda munhu zvaimbonzi HIV. utachiwana ichi chinobata mumwe chete boka masero vanobatanidzwa muchitokisi-yairevererwa kutapata - T-lymphocytes. Pakutanga akanga chete unonetsa mashandiro masero aya, uye ipapo kuvaparadza chose. Nokuda kwechikonzero ichi, vanhu muviri anova kuzvidzivirira pamusoro siyana zvigare - nyore, utachiona uye hunokuvadza. Mukuwedzera, chinokosha kwakaderera dziviriro yezvirwere mumuviri mune ramangwana chinokurwadzai kukura dzakasiyana-siyana rakaipa bundu mhando.
