Isesengura ry’icyorezo cya virusi itera SIDA-1 ku isi no mu karere mu 1990-2024: isuzuma rusange, ubushakashatsi ku isi, n’isesengura ry’ikwirakwira ry’icyorezo

Intangiriro

Ubushakashatsi buherutse gusohoka muriIndwara zandura za Lancet(2026) itanga isesengura ryimbitse ku isi hose ry’icyorezo cya virusi itera SIDA-1 kugeza ubu, rihuza amakuru y’isuzuma rusange n’ubushakashatsi ku isi yose bwo kugenzura ingirabuzimafatizo.

Mu guhuza amakuru yari ahari mbere (1990–2021) n'amakuru mashya yakusanyijwe, ubushakashatsi bwashyizemo ibirenzeRaporo miliyoni 1.39 z'imyandikire y'ibinyabuzima byanduye agakoko gatera SIDA-1 zaturutse mu bihugu 154 zakusanyijwe hagati ya 1990 na 2024Bakoresheje imibare y’abantu banduye agakoko gatera SIDA igereranywa na UNAIDS nk’ibintu biremereye, abashakashatsi bakoze amakarita mpuzamahanga n’ay’uturere asobanura uko ubwoko bwa VIH-1 bukwirakwira mu gihe n’ahantu, imiterere ya recombinant circulating (CRFs), n’imiterere yihariye ya recombinant (URFs) ikwirakwira.

Ibyavuye mu bushakashatsi bigaragaza ko nubwo imiterere y’ubwoko bwa VIH-1 ku isi yakomeje kuba ihamye mu myaka makumyabiri ishize, hari impinduka zikomeye mu turere, cyane cyane bitewe n’ubwiyongere bw’ubwoko bw’udukoko two mu bwoko bwa VIH-1 n’ubwiyongere bw’uturemangingo.

Amasomo y'ibanze

Virusi itera SIDA (HIV-1) igaragaza ubwinshi bw’uturemangingo bitewe n’umuvuduko wayo wo hejuru mu guhinduranya imiterere y’umubiri, ubushobozi bwo kongera kwihuza kw’uturemangingo, ndetse n’uburyo bwo kwanduzanya mu gihe kirekire.

Uku guhindagurika kw'uturemangingo (genetic variation) bigira ingaruka zikomeye kuri:

• · kugenzura molekile,
• · Isuzuma ry'imikorere y'isuzumabumenyi,
• · kugenzura ubudahangarwa bw'imiti igabanya ubukana bw'udukoko duto (antiretroviral),
• · n'ingamba zo guteza imbere inkingo.

Ubushakashatsi bwari bugamije kugaragaza imiterere y’ikwirakwizwa ry’ubwoko bwa VIH-1 n’ubwoko bwa recombinant ku isi hose no mu karereKuva mu 1990 kugeza 2024, itanga uburyo bushya bwo kurwanya icyorezo cya SIDA mu gukumira no kurwanya icyorezo ku isi.

Igishushanyo mbonera n'uburyo bwo kwiga

Abashakashatsi bakoze isuzuma ryakozwe ku buryo bunoze rya PubMed, Embase, Global Health, CINAHL databases, basobanura ubushakashatsi bwasohotse hagati ya tariki ya 1 Mutarama 2022, na 22 Mutarama 2025.

Byongeye kandi, amakuru yakusanyijwe binyuze mu muyoboro w’ikoranabuhanga uhuza ibikorwa by’ubushakashatsi ku ndwara zandurira mu cyorezo cya SIDA ku isi.

Amakuru yemewe arimo:

• · Amakuru y’ubwoko bwa molekile ya VIH-1,
• · Ahantu ho gufatira ingero hasobanuwe neza,
• · amatariki yo gukusanya,
• · n'imibare ihagije y'icyitegererezo.

Amakuru ya nyuma yari arimo:

• · Inyandiko 1.395.222 z'isesengura ry'imiterere y'umubiri wa virusi itera SIDA-1 
• · Ibihugu 154 
• · Ibihe bitandatu by’icyorezo:1990–1999, 2000–2004, 2005–2009, 2010–2014, 2015–2019, 2020–2024.

Ikwirakwira ry’imiterere y’uturemangingo twa VIH-1 ku isi no mu turere ryagenwe hakoreshejwe uburyo bwo gupima uburemere bwahinduwe na UNAIDS.

Ikwirakwizwa ry'ubwoko bwa VIH-1 ku Isi: Ubwoko bwa C buracyari bukomeye

Mu gihe2020–2024, ubwoko bwa C bwakomeje kuba ubwoko bwiganje bwa virusi itera SIDA-1 ku isi, bugizwe na:

Muri rusange, imiterere ya recombinant (harimo CRF na URF) yanganaga na22.4% by'abanduye agakoko gatera SIDA ku isi, bigaragaza uburyo ubwoko butandukanye bw'uturemangingo twa VIH-1 bugenda bwiyongera.

Ubwoko bwa C bukomeje kwiganza cyane cyane muri:

• · Afurika y'Amajyepfo,
• · Aziya y'Amajyepfo,
• · n'ibihugu byinshi byo muri Afurika y'Iburasirazuba.

Kubera ko utu turere dufite igice kinini cy’umubare munini w’abanduye agakoko gatera SIDA ku isi, ukwiganje kwa subtype C bigira ingaruka zikomeye ku miterere y’ikwirakwizwa ry’agakoko ku isi yose.

Itandukaniro ry'uturere: Imiterere itandukanye y'ubwihindurize mu migabane yose

Nubwo imiterere y’icyorezo cya SIDA-1 ku isi isa n’aho ihamye, imiterere y’uturere irimo guhinduka cyane.

Afurika y'Amajyepfo na Aziya y'Epfo: Ubwiganze bw'ubwoko bwa C buhoraho

Afurika y'Amajyepfo na Aziya y'Epfo bikomeje kurangwa cyane n'uburyo ubwoko bwa C buzenguruka.

Muri utu turere dufite umutwaro mwinshi, ubwoko bwa C bugaragaza umubare munini wa virusi zikwirakwira, bigatuma ari bwo bwa mbere butera ikwirakwira ry’ubwoko bwa C ku isi.

Ariko, ubushakashatsi bugaragaza kandi ko uburyo bwo gupima ingero za molekile mu turere tumwe na tumwe dukorerwamo ibintu byinshi bukiri buke, bigaragaza ko hakenewe imbaraga zo kugenzura kugira ngo hamenyekane neza ubwoko butandukanye bwa virusi zo mu gace runaka.

Amerika ya Ruguru na Amerika y'Epfo: Gukomeza kwa Subtype B

Ubwoko bwa B bukomeje kuba umurongo nyamukuru uzenguruka muri:

• Amerika ya Ruguru,
• · Amerika y'Epfo.

Utu turere tugaragaza imiterere ihamye y’icyorezo cya molekile ugereranije n’utundi turere duhinduka vuba mu buryo bwihuse.

Uburayi bw'Iburengerazuba n'Uburayi bwo Hagati: Ubwiyongere bw'Ubudasa bw'Ingirabuzimafatizo

Uburayi bw'Iburengerazuba n'Uburayi bwo Hagati burimo guhinduka buhoro buhoro kuva ku cyorezo cyiganjemo ubwoko bwa B kijya mu turere dutandukanye twa virusi.

Ibyerekezo by'ingenzi birimo:

• · Kugabanuka kw'igipimo cya B,
• · kongera uruhare rw'ubwoko bwa recombinant,
• · kwiyongera kw'imiryango itari iya B.

Izi mpinduka zigaragaza ko itandukaniro ry’uturemangingo twa VIH-1 ririmo kugenda rirushaho kuba ingenzi ndetse no mu turere twiganjemo ubwoko bwa B mu mateka.

Aziya y'Iburasirazuba: Kwaguka vuba kw'imiterere y'ibimera bivanze

Aziya y'Iburasirazuba yagaragaje imwe mu mpinduka zikomeye mu bijyanye n'icyorezo.

Ubushakashatsi bwagaragaje ko:

• · CRF07_BC yiyongereye cyane uko igihe cyagiye gihita,
• · ubwoko bwa B bwaragabanutse cyane.

CRF07_BC yiyongereye ugereranyije n'igihe kingana na13.1% hagati ya 2000–2004 kugeza kuri 48.1% hagati ya 2020–2024, bigaragaza impinduka ikomeye mu ikwirakwizwa ry'icyorezo cya virusi itera SIDA mu karere.

Iri hinduka rigaragaza akamaro ko kugenzura buri gihe molekile mu turere aho imiterere y’uturemangingo irimo kwiyongera.

Ubwoko bw'ibiteranyo: Igice kirimo kwiyongera cy'ubusumbane bw'abanduye virusi itera SIDA ku isi

Igipimo cy'ubwoko bwa recombinant cyariyongereye ku isi mu myaka yashize:

• · 2000–2004: hafi 20.8%
• · 2010–2014: hafi 24.2%
• · 2020–2024: hafi 22.4%

Nubwo igipimo cy’isi cyagabanutseho gato mu gihe cya vuba aha, imiterere y’ibikomoka ku bimera bishya ikomeje kwaguka mu turere twinshi, cyane cyane:

• · Aziya y'Iburasirazuba,
• · Uburayi bw'Iburengerazuba n'Uburayi bwo Hagati.

Ubushakashatsi bwerekana ko imiterere y’uturemangingo dushobora kuba tugisuzugurwa mu buryo bumwe na bumwe kuko gahunda nyinshi zo kugenzura zishingiye ahanini ku bice bya genome, bishobora kutagaragaza neza imiterere igoye yo gusubiramo.

Gushimangira uburyo bwo kugenzura genome bizaba ingenzi cyane cyane mu turere dufite umubare munini w’abandura virusi itera SIDA kandi umubare munini w’abandura wiyongera.

Ingaruka ku buzima rusange n'ubuvuzi

1. Sisitemu zo gusuzuma zisaba isuzuma rihoraho ry’ubwoko butandukanye

Kongera ubwinshi bw'uturemangingo twa virusi itera SIDA bigaragaza akamaro ko gukomeza gusuzuma ikoranabuhanga ryo gusuzuma indwara mu nkomoko zitandukanye za virusi.

Nubwo uburyo bwo gupima virusi itera SIDA n’uburyo bwo gupima umubare w’abanduye bwagaragaje ko bukoreshwa cyane, kugenzura buri gihe ubwoko bw’udukoko tugaragara hamwe n’ubwoko bw’udukoko tubiri biracyari ngombwa.

Igenzura ry'ejo hazaza rigomba gushyira hamwe:

• · Indwara z'ikwirakwira ry'ibinyabutabire,
• · Gukurikirana imikorere y'isuzumabumenyi,
• · n'isesengura ry'ubwiyongere bw'ikwirakwira rya virusi.

2. Igenzura ry’ubudahangarwa bw’imiti rikeneye ubwishingizi bwagutse bw’ibikomoka ku maraso

Kwaguka kw'amoko atandukanye ya VIH-1 bishobora kugira ingaruka ku kugaragara, ku kumenyekana no gusobanura impinduka ziterwa no kudakira.

Hari ubushakashatsi bwagaragaje ko ubwoko bwihariye bwa VIH-1, harimo n'ubwoko bufitanye isano na A6/A1, bushobora kuba bufitanye isano n'ibyago byo kunanirwa kwandura virusi mu buryo bumwe na bumwe bwo kuvurwa na cabotegravir/rilpivirine bumara igihe kirekire.

Ariko, ingaruka zo kurwanya indwara ziterwa n'ibintu byinshi, harimo:

• · impinduka z’ibanze zo kurwanya indwara,
• · Amateka y'ubuvuzi,
• · Gukurikiza amategeko,
• · n'inkomoko y'uturemangingo twa virusi.

Bityo, kugenzura uburyo bwo kurwanya indwara zitandukanye bikomeje kuba ingenzi cyane.

3. Guteza imbere inkingo bigomba kuzirikana ubwoko butandukanye bwa virusi zo mu turere

Ubwinshi bw'uturemangingo twa VIH-1 buracyari kimwe mu bibazo bikomeye mu iterambere ry'inkingo.

Ikwirakwira ry’ubwoko butandukanye bw’udukoko n’ubwoko bw’udukoko twongera gutera imbere rigaragaza ko hakenewe ingamba zo gukingira zishingiye kuri ibi bikurikira:

• · ubwoko bw'ibinyabutabire bizenguruka mu karere,
• · Impinduka mu mikorere ya virusi,
• · no gukingira ubudahangarwa bw'umubiri mu buryo bwagutse.

Uburyo bumwe ku isi yose bushobora kudakemura byimazeyo ubudasa bw’agakoko gatera SIDA-1 gakwirakwira ku isi yose.

Umwanzuro

Iri sesengura rikomeye ku isi ku bijyanye n'icyorezo cya VIH-1 rigaragaza ko imiterere y'icyorezo ku isi yose irangwa no gukomeza no guhinduka.

Nubwo ubwoko bwa C bukomeje kuba kimwe cya kabiri cy’ubwandu bwa VIH-1 ku isi, imiterere y’uturemangingo two mu turere irimo guhinduka vuba, aho imiterere y’uturemangingo two mu bwoko bwa recombinant irushaho kuzana icyorezo mu turere nka Aziya y’Iburasirazuba n’i Burayi.

Ibyavuye mu bushakashatsi bishimangira akamaro ko kugenzura mu buryo buhoraho, gusuzuma indwara zitandukanye, hamwe n'uburyo bwo guhuza uburyo bwo gusuzuma genome kugira ngo bishyigikire gukumira virusi itera SIDA neza, gukurikirana uburyo bwo kuvura, ndetse no guteza imbere urukingo rw'ejo hazaza.
