Apho u AIDS?

Yintoni isifo sikagawulayo? Virus? Disease? Apho u AIDS? izaziso benkonzo karhulumente kumabonwakude nonomathotholo bebesoyikisa kule kota ubize ukulwa nayo.

Kuqala kwinto zonke, simele siqonde ukuba AIDS - a syndrome of lufundiwe (ngenxa yokugula) immunodeficiency. Baya musa ukuba ayosuleleki, ekubeni ethile uhlobo iintsholongwane, kodwa sifo. Kwelinye icala, a syndrome - indibaniselwano iimpawu kwenzeka ngokuchasene nentsukaphi sifo njenge-HIV. Amaninzi, ezo bemeko- zenze ngomxholo loluntu eli gama lulungiselelwe ukuba ixesha HIV okt human immunodeficiency virus. Ngenxa yesi sizathu, akayi oluchanekileyo ngakumbi ukuba acele "apho wenza AIDS?" Kwaye "apho wenza i-HIV?". Ke apho wenza le ntsholongwane?

Kodwa ekubeni abantu abaninzi badla kucela kumaqonga: "Uvelaphi AIDS", thina, mhlawumbi, impendulo yalo mbuzo.

Amatyala yokuqala ezifunyenwe immunodeficiency syndrome bafunyanwa ngamakhoboka eziyobisi amafanasini. Kungekudala emva koko, kwafunyaniswa ukuba phakathi kwabantu kule syndrome nazo rhoqo ze abo benze ngaphambili ukutofelwa igazi okanye iziyobisi. Yaye yee- Ekuqaleni kwenkulungwane yama-20, izazinzulu American uRobert Gallo kunye M. Essex kuqala wacebisa ukuba zonke iimeko ukuncitshiswa amajoni omzimba, hayi ziyanyangeka, isiphumo esi sifo. Ngenxa yazo, esi sifo sibangelwa uhlobo lwe Igciwane ebangela umntu osulelekileyo kuhlobo oluthile wegazi.

Izifundo eziye kuqhutywa kamva wabonisa ukuba AIDS iqalisa umntu ngaphambili losulelwe yi-HIV. Le ntsholongwane kuchaphazela enye kuphela iqela leeseli ababandakanyekayo iseli-mediated okukwazi - T-lymphocyte. Ekuqaleni ephazamisana kuphela umsebenzi ezi seli, uze kubatshabalalisa ngokupheleleyo kubo. Ngenxa yesi sizathu, umzimba womntu uba ukuzikhusela iintsholongwane ezahlukeneyo - elula, iintsholongwane nomngundo. Ukongeza, ukuba buthathaka elibalulekileyo amajoni omzimba kwixesha elizayo kuphakamisa uphuhliso iindidi uhlobo ithumba.

Ngokubanzi, umbuzo, apho wenza AIDS kuqala, waphendula thina. Kucacile ukuba imvelaphi AIDS ibangwa yi -human immunodeficiency virus. Kwaye kuya kuba kuphosakele bathi HIV - i-arhente causative ka-AIDS. Le yenye amanyathelo (yokugqibela okanye ukugcina). Kodwa ngaba le ntsholongwane phi na?

Kukho imibono eziliqela malunga nemvelaphi yayo;

• Theory of Robert Gallo. Le Scientist ukholelwa ukuba i-original-HIV iinkawu eluhlaza bendinokuhlala eAfrika. Ngaxa lithile, lo Igciwane yingozi wakwazi ukoyisa umqobo zenye bawelela abantu. Ngaphandle monkeys eluhlaza emngciphekweni, kunye nezinye obeku-, ezifana bangafani kunye mangabey ezimhlophe-ijwabu Afrika, ekubeni izilwa-HIV zabonwa egazini labo. Kodwa apho wenza oku Igciwane e iinkawu, akukho bani owaziyo.

• HIV - impazamo Scientists. Abanye bakholelwa ukuba intsholongwane esibulalayo sisiphumo eksperimenti ayiphumelelanga apho izazinzulu yoma zenkulungwane yama-20 bazama ukwenza ugonyo nxamnye hepatitis B nepoliyo. Oko ngeli xesha, amatyala AIDS abantu abhalwe kuqala eUnited States. Hi ndlela leyi, ipoliyo kunye hepatitis B sogonyo idaliwe ukusuka izinto zemfene eziphilayo. Kwaye apha akunakwenzeka ukuba uqaphele udibaniso kwithiyori elidlulileyo.

• HIV - esi sifo ayikho! Kukho unyango lwe-antiretroviral, nto leyo ebangela kamva AIDS kunye nabantu. Kubonakala ukuba HIV - nto nje iinkampani nentsomi zamayeza abafuna imali engaka.

• HIV - isixhobo zebhayoloji owadala izazinzulu American ukujongela indawo ye-USSR ehlabathini.
