Lapho benza AIDS?

Uyini-AIDS? Virus? Izifo? Lapho benza AIDS? Public inkonzo izimemezelo kamabonakude ukuba asabise nathi leli gama futhi ushayele ukuze kulwiwe nakho.

Okokuqala, kufanele siqonde ukuthi AIDS - a syndrome ka aluthola (ngenxa yokugula) immunodeficiency. Abanaso batheleleke, njengoba singasebenzi ezinye uhlobo lwama-bacterium, kodwa a syndrome. Ngenxa yalokho, syndrome - inhlanganisela yimuphi izimpawu ezenzeka ngokumelene isizinda isifo esinjengo-HIV. Ngokuvamile, abadali izimakethe kwi social indaba ephathwayo leli gama ehloselwe njengoba isikhathi HIV okungukuthi human immunodeficiency virus. Ngenxa yalesi sizathu, elungile ngaphezulu bekungeke kudingeke ukuba ubuze "lapho benza AIDS?" Futhi "lapho wenza-HIV?". Ngakho lapho benza lokhu igciwane?

Kodwa njengoba abantu abaningi bavame ukubuza izinkundla: "Lapho benza AIDS", mhlawumbe, impendulo yalo mbuzo.

Amacala lokuqala atholwe immunodeficiency syndrome etholakale yezidakamizwa nongqingili. Ngokushesha ngemva kwalokho, kwatholakala ukuthi phakathi abantu yilesi sifo njalo nazo futhi labo ababemazi ngaphambili, wayenze ukumpontshelwa igazi noma izidakamizwa. Futhi in the Eighties okuqala ekhulu lama-20, ososayensi American Robert GALLO futhi M. Essex wayengowokuqala ukusikisela ukuthi zonke izimo lokwehliswa kwesimiso somzimba sokuzivikela ezifweni, akuzona esilaphekayo, kuwumphumela sifo. Ngokombono wabo, lokhu sifo sibangelwa uhlobo retrovirus edala umuntu onegciwane uhlobo oluthile lomdlavuza wegazi.

Izifundo ukuthi sezenziwe kamuva wabonisa ukuthi AIDS eba umuntu ayekade utheleleke nge-HIV. Lokhu igciwane sithinta umuntu oyedwa kuphela iqembu lamaseli ehilelekile amasosha omzimba cell aqashwe - T-lymphocyte. Ekuqaleni lamane nje ephazamisa nokusebenza kwalezi zici amaseli, bese ukubhubhisa ngokuphelele kubo. Ngenxa yalesi sizathu, umzimba womuntu uba ukuzivikela nezilwanyana ezincane ezahlukene - elula, amagciwane athile kanye nesikhunta. Ngaphezu kwalokho, lube buthaka enkulu kwesimiso somzimba sokuzivikela ezifweni esikhathini esizayo kuphakamisa ukuthuthukiswa ezihlukahlukene ebulalayo isimila hlobo.

Ngokuvamile, umbuzo, lapho benza AIDS lokuqala, thina waphendula. Kuyacaca ukuthi umsuka AIDS kubangelwa human immunodeficiency virus. Futhi ngeke kube okungafaneleki ukwenza ukuthi i-HIV - i-ejenti causative yingculaza. Lena enye yezinhlobo ezingu izinyathelo (igcinwe noma ukugcina). Kodwa ingabe lokho igciwane ukuza lapho?

Kunemibono eminingana ngemvelaphi yayo:

• Theory ka Robert Gallo. Lokhu usosayensi ukholelwa ukuthi yasekuqaleni abane-HIV babe izinkawu oluhlaza ezihlala e-Afrika. Ngesinye isikhathi esededelwe, le-retrovirus esiyingozi wakwazi yokunqoba isithiyo esibangwa zinhlobo futhi bawelela abantu. Ngaphandle izinkawu oluhlaza basengozini, namanye wezinkawu, ezifana nama-chimpanzee mangabey Afrika elimhlophe-ijwabu leso, njengoba amasosha omzimba HIV zitholiwe igazi labo. Kodwa lapho wenza lokhu retrovirus e izinkawu, akekho owaziyo.

• HIV - iphutha Scientists. Abanye bakholelwa ukuthi igciwane elibulala kuwumphumela ukuhlola kuhlulekile lapho ososayensi e ngeminyaka yoma kwekhulu lama-20 wazama ukwakha lokugoma ngokumelene hepatitis B no poliomyelitis. Kwakuthinta ngalesi sikhathi, izimo AIDS e abantu sokuqala esilotshwe e-United States. By the way, uvendle kanye ne-hepatitis B umgomo wadala kusukela yemvelo impahla chimpanzee. Futhi lapha akunakwenzeka ukuqaphela uxhumano tiyori odlule.

• HIV - lesi sifo hhayi! Kube ukwelashwa ngezidambisi gciwane, kamuva elibangela ingculaza kanye womuntu. It kuvela ukuthi-HIV - kungcono nje izinkampani inganekwane ezithaka imithi abafuna imali engaka.

• HIV - isikhali begazi owadala ososayensi American ukubhodloza isikhundla wase-USSR emhlabeni.
