Chifukwa chiyani palibe katemera wa chiwindi cha C?

3 Zopinga Zopanga Katemera Woteteza Katemera

Katemera wakhala akuwona ngati chinsinsi chothetsera miliri yomwe yawononga thanzi la anthu, kuphatikizapo polio, masisoni, rubella, ndi diphtheria.

Zotsatira zofananazi zawoneka ndi katemera wa hepatitis A , womwe unatulutsidwa mu 1995, komanso katemera wa hepatitis B , womwe unayamba mu 1981. Pogwiritsa ntchito njira ya katemera, chiwerengero cha matenda a hepatitis A ndi B ku United States ndi 95 peresenti ndi 90 peresenti, motero.

Izi, mwachibadwa, zimapangitsa kuti matenda a chiwindi a chiwindi afike poyera ndi mafunso chifukwa chake sitiyenera kukhazikitsa katemera wopewa chomwe chiri chovuta kwambiri pa mitundu itatu yaikulu ya chiwindi.

Kuchuluka kwa Matenda a Hepatitis C

Kukula kwa vutoli kuli kodabwitsa. Malinga ndi kafukufuku wochokera ku World Health Organization, anthu oposa 70 miliyoni ali ndi kachilombo ka HIV kameneka (HCV), kuphatikizapo anthu oposa 3 miliyoni a ku America. Mwa amenewa, pafupifupi 400,000 amafa ndi matendawa chaka chilichonse, makamaka chifukwa cha khansa ya chiwindi ndi chiwindi .

Komanso, mwazirombo zoposa 1,5 miliyoni zomwe zimachitika chaka chilichonse, paliponse pa 70 peresenti mpaka 85 peresenti zidzapitirira kukhala ndi matenda aakulu omwe 70 peresenti padzakhala ndi matenda a chiwindi.

Kuyika manambalawa kukhala ofunika kwambiri, kuchuluka kwa matenda a HCV atsopano kumakhalako kwa kachilombo ka HIV , pamene chiwerengero cha anthu omwe ali ndi matenda a chiwindi cha C chiwerengero cha kachilombo ka HIV (33 miliyoni).

Mavuto Polimbikitsa Katemera

Ngakhale pali mankhwala omwe amatha kuchiza anthu ambiri okhala ndi HCV, njira yokhayo yothetsera mliliyi ndi katemera wotsika mtengo komanso wotetezeka. Pakalipano, asayansi akhala akulembedwera mu kuyesa kwawo kupeza.

Ngakhale ambiri amakhulupirira kuti katemera wa chiwindi cha hepatitis C amatha kupezeka (ngakhale kuposa, mwinamwake, kuposa katemera wa HIV ), pali zingapo zofunikira zothetsera.

Mwa iwo:

1. HCV imakhala ndi mavuto ambiri omwe katemera umodzi sungagwire ntchito. Zonse zanenedwa, pali asanu ndi awiri akuluakulu a HCV genotype , omwe ali ndi zofanana ndi zikhalidwe. Katemera umadalira zizindikiro izi kukhazikitsa, pakati pazinthu zina, pamene molecule ya katemera imayenera kulumikizana ndi kachilombo kuti asinthe. Taganizirani izi ngati chinsinsi. Ndi kugwirizana kulikonse, malo a fungulo-ndi njira yomwe ntchito zofunikira-zimasiyanasiyana kwambiri. Momwemo, pamene kuyimitsa kamodzi kamodzi kowonjezera, kungangowonjezera wina kutenga malo ake.
2. HCV imayenda nthawi zonse komanso molakwika. Ngati kachilomboka, kachilombo ka HIV kamakhala kosavuta kuwona zolakwika zokhudzana ndi chibadwa pamene zimapanga makope ake enieni. Izi zikutanthawuza kuti, ngakhale pakati pa maginito amodzi, pali zowerengeka zopanda malire komanso zosiyana kwambiri ndi tizilombo toyambitsa matenda. Chifukwa cha ichi, ngakhale katemera atatha kuteteza kachilombo kamodzi ka HCV, mwina pangakhale magawo osagwirizana ndi katemera. Ngati ndi choncho, kachilombo kakang'ono kamene kameneka kanakhoza kutembenuzidwa kosatsekedwa ndipo, potero, sichipewa zotsatira za katemera.
3. Pali kusowa kwa zinyama zomwe zimachita kafukufuku. Ndi HIV, mwachitsanzo, asayansi amatha kuchita maphunziro a nyama chifukwa pali kachilombo kofanana komwe kamene kamatchedwa HIV (SIV) kamene kamapezeka m'matumbo. Palibe mtundu woterewu wa mtundu wa HCV. Pakadali pano, asayansi atulukira mavairasi a HCV ngati mahatchi, makoswe, ndi mahatchi, omwe ali, abwino, achibale. Pomwe zikunenedwa, magulu ena ofufuza apanga njira zomwe angayambitsire kachilombo ka HIV ndikupeza bwino, momwe nthawi yeniyeni imakhudzira maselo komanso momwe angapewere izo.

Malire Ofufuza

Ngakhale izi zili zopinga zambiri, asayansi akuyandikira kwambiri kuti adziwe njira yoyenera katetezera matenda a HCV. Ngakhale kuti ambiri amakhulupirira kuti katemera umodzi sungathe kuchitira mitundu yonse yambiri ya katemera, ambiri amakhulupirira kuti mfundo zomwe zimayambitsa katemera wina ziyenera kukhala "zopangidwira" kuti apange ena

Pali ovomerezeka angapo omwe akufunsidwa. Ena mwa iwo, ofufuza ku Australia akufufuzira katemera yemwe poyamba anawongolera kuti asateteze matenda a HCV. Katemera, yemwe wasonyeza kale kukhala wotetezeka mwa anthu, akuyesedwa kuyesedwa kwakukulu pakati pa ndende ku New South Wales, mudzi umene ma HCV amawonekera kwambiri.

Pakalipano, asayansi ena akuyesa kufufuza zochitika za majeremusi monga mavairasi a HCV m'mahatchi, omwe ali msuweni wapafupi kwambiri ndi mtundu womwe umawoneka mwa anthu. Ambiri amakhulupirira kuti ngati asayansi amatha kutsegula kapena kuteteza kachilombo ka HIV, mfundo zomwezo zingagwiritsidwe ntchito kwa mtundu wa anthu, kutsegula chitseko kwa katemera wathandizira kulikonse kuyambira zaka zisanu mpaka khumi.
