Kodi G4 ndi chiyani (ndipo tiyenera kuda nkhawa)?

Kodi G4 ndi chiyani (ndipo tiyenera kuda nkhawa)?Nkhani

ZOCHITIKA ZA CORONAVIRUS: Akatswiri akamaphunzira zambiri za coronavirus yatsopano, nkhani komanso kusintha kwazidziwitso. Zatsopano pa mliri wa COVID-19, chonde pitani ku Malo Othandizira Kuletsa ndi Kupewa Matenda .

Chinthu chotsiriza chomwe aliyense akufuna kumva ndi kuthekera kwina mliri . Komabe, kafukufuku wofalitsidwa posachedwa mu Kukula kwa National Academy of Science (PNAS) yadzetsa nkhawa zambiri. Ndizokhudza gulu lachilendo la matenda a chimfine cha nkhumba zomwe ofufuza amati ali ndi kuthekera kufalikira kwa anthu. Nazi zomwe tikudziwa.



Kodi chimfine cha nkhumba cha G4 ndi chiyani?

Gulu la mavairasi omwe atchulidwa mu kafukufuku wa PNAS amadziwika kuti ndi G4 Eurasian (EA) avian monga ma virus a H1N1-kapena, G4 chabe. Ndi mtundu winawake wa chimfine cha nkhumba (chifukwa cha fuluwenza A virus) chomwe chikufalikira pakati pa nkhumba ku China. Pali mitundu inayi yayikulu yamatenda a fuluwenza (A, B, C, ndi D). Fuluwenza A ndiye gulu lofala kwambiri lomwe limayambitsa miliri.



Kachilombo ka nkhumba katangobweretsa mliri wa 2009, mabungwe aboma yaku China adagwirizana ndi World Health Organisation komanso asayansi ochokera kumayunivesite aku China ndi Britain kutsatira ndikuwona kuchuluka kwa nkhumba ngati ali ndi kachilombo koyambitsa matendawa.

Kuyang'anitsitsa kumeneku kunapeza zitsanzo za nkhumba zokwana 179 zomwe zimawoneka kuti zili ndi kachilombo ka fuluwenza A, ndipo kuyambira 2016 kachilombo ka HIV ka G4 H1N1 kamakhala kachilombo kosavuta kwambiri. Ngakhale kufalitsa nkhani kwaposachedwa ndi koyamba kuti anthu wamba azimva za G4 swine flu-sizolondola kwenikweni kuyitcha yatsopano.



Kodi G4 ingayambitse mliri wa anthu?

G4 ili ndi zinthu zina zatsopano poyerekeza ndi mitundu ya chimfine. Koma ndizofanana ndi kachilombo ka H1N1 ka 2009 kuseri kwa mliri wa swine flu zomwe ndizodetsa nkhawa.

1. Imatha kutenga anthu.

Monga kachilombo ka H1N1 ka 2009, kachilombo ka G4 kamatha kulumikizana ndi maselo m'mapapu a anthu, omwe amalola kuti ayambitse matenda mwa anthu. Si ma virus onse a nkhumba omwe amatero, ndichifukwa chake sikuti nkhumba zonse zimayambitsa matenda a anthu.

M'malo mwake, kafukufukuyu adawonetsa kuthekera kwa kachilomboka kupatsira anthu poyesa kuti awone ngati anthu omwe akugwira ntchito ndi nkhumba apanga ma antibodies a kachilomboka. Kuchokera ku 2016 mpaka 2018, 10.4% ya ogwira ntchito yopanga nkhumba omwe adayesedwa anali ndi chiyembekezo cha antibody (kutanthauza kuti matenda adachitika).



2. Anthu ambiri amasowa chitetezo chokwanira.

Monga kachilombo ka H1N1 ka 2009, ma virus a G4 akuti ali ndi mitundu yophatikizira majini ochokera ku ma virus a fuluwenza omwe amapezeka mwa anthu, mbalame, ndi nkhumba. Izi zitha kuchitika chifukwa chobwezeretsanso, njira yomwe ma virus angapo amasakanikirana ndi wolandila-mu nkhumba iyi-amasinthanitsa majini, ndikupanga kachilombo koyambitsa matenda a fuluwenza ndi zatsopano. Vuto latsopano likatuluka, anthu ambiri amasowa chitetezo chokwanira ndikutenga matendawa. Vuto la mliri wa H1N1 mu 2009 lidachitika chifukwa chobwezeretsanso.

3. Zitha kukhudza kwambiri achinyamata.

Pali zina zochepa zokhudzana ndi zomwe apeza phunziroli, kuphatikiza chiwopsezo chachikulu cha ma antibody omwe amapezeka pakati pa achinyamata azaka zapakati pa 18 mpaka 35 a nkhumba (motsutsana ndi achikulire). Izi zitha kuyimira kuchepa kwazinthu zomwe zimawonedwa kuti ndi odwala komanso ocheperako, omwe amachititsa chidwi kuyambira pomwe mliri wa H1N1 unayambitsa ambiri amamwalira azaka 18 mpaka 64 zakubadwa.

4. Anthu omwe sanakhudzane ndi nkhumba anali ndi kachilombo.

Chithandizo cha antibody ku G4 chimfine chidapezekanso mu 4% ya zitsanzo za anthu a 230 ochokera ku China omwe sanalumikizane ndi nkhumba zoyesedwa. Izi zikufanana ndi mliri wa H1N1 wa 2009 momwe odwala omwe adadziwika kale anali nawo osalumikizana ndi nkhumba .



5. Imafalikira mwa kukhudzana kapena m'malovu opuma.

Kuphatikiza apo, zomwe apeza mu labotale zikuwonetsa kuti kachilomboka kangathe kufalikira mwa kukhudzana mwachindunji kapena m'malovu opumira. Matendawa, kuphatikiza kusatetezedwa ku mtundu wina wa fuluwenza wa G4 kuchokera ku katemera wa fuluwenza wa anthu omwe alinso m'gulu la kachilombo koyambitsa mliri.

Kodi tiyenera kukhala okhudzidwa motani?

Choyamba, tiyenera kupatula manambalawo pang'ono pang'ono.



Zimakhudza anthu ochepa.

Ngakhale panali zitsanzo zabwino za 179 za nkhumba zoyesedwa, izi zikuyimira kudzipatula kotsika kwambiri. Pazotsatira zabwino za 179, 136 idachokera pagulu la nkhumba zosakhala zodziwika pafupifupi 30,000. Izi zikuyimira kuchuluka kwaokha kwa 0,45%. Zitsanzo zotsalira za 43 zotsalira za 179 zabwino zonse zidachokera kwa anthu opitilira 1,000 mphuno zamphongo kapena mapapu omwe adatengedwa kuchokera ku nkhumba zowonetsa kupuma kwakanthawi kodzipatula kwa 4.23%. Kuphatikiza apo, nkhumba zonse zomwe zayesedwa zikuimira chiwerengero chochepa kwambiri cha nkhumba zonse ku China-zomwe zitha kukhala 500 miliyoni.

Palibe kufala kodziwika pakati pa anthu.

Pakadali pano, palibe kufala komwe kwadziwika komwe kwawonedwa ndi G4 swine flu pakati pa anthu. Mliri ukhoza kuchitika pokhapokha kufalikira kwa munthu ndi munthu kumachitika. Mbiri yakale ikutiphunzitsa kuti kufalikira kuchokera ku nkhumba kupita kwa anthu-ma virus osiyana-siyana omwe awonedwa ndi G4 fuluwenza amachitika chaka chilichonse ndi ma virus ena a fuluwenza, koma nthawi zambiri samakhala kukhazikika . Pakadali pano, tiribe chifukwa chabwino choganiza kuti G4 swine flu ingayambitse china chilichonse. Pomaliza, tikudziwa kuti machitidwe, monga kudya nkhumba, amatero ayi lolani kuti kachilombo ka HIV kamafalikira kuchokera ku nkhumba kupita kwa anthu.



Sinafike ku United States panobe.

Pakadali pano, Centers for Disease Control and Prevention (CDC) yatsimikizira kuti ma virus a G4 sanapezeke mu nkhumba kapena anthu ku United States.

Ndizoti, bukuli la G4 swine flu likufanana ndi vuto la mliri wa H1N1 2009, chifukwa chake payenera kukhala nkhawa. Kufalikira kosalekeza kwa nkhumba ndikupitilira kufalikira kwa anthu kumatha kuloleza kusinthana kwina kwa majini - omwe amadziwikanso kuti kutsitsimutsa-kuchitika, zomwe zingalole kuti vutoli likhale loyenera kuyambitsa mliri. Kutanthauza, imatha kusintha ndikusintha mosavuta kuchokera kwa munthu kupita kwa munthu.



Kodi U.S. akuchita chiyani kukonzekera?

CDC ikuchita izi:

  • Kugwira ntchito ndi akuluakulu azaumoyo ku China kupeza kachilombo ka HIV
  • Kugwiritsa ntchito Chida Choyesera Chiwopsezo cha Fuluwenza (IRAT) kuti awone kuwopsa kwa kachilomboka kamayambitsa mliri
  • Kuwunika komwe katemera waposachedwa omwe akuphunzira motsutsana ndi ma virus a chimfine angateteze ku kachilomboka
  • Kuwona ngati mankhwala omwe ali ndi chimfine omwe alipo alipo amateteza ku kachilomboka

Mliri wa fuluwenza wa H1N1 wa 2009 unali mliri woyamba pafupifupi zaka 40. Kachilombo ka chimfine cha H1N1 ka 2009 komwe kanayambitsa kachilomboka kanali kotengeka kwambiri — mpaka pa Milandu 60.8 miliyoni ku U.S. mchaka chake choyamba ndipo pafupifupi 12,500 amamwalira. Koma, kufera kwake kunali kotsika poyerekeza ndi miliri yam'mbuyomu, mwina chifukwa chakumvetsetsa bwino kwa kufalikira kwa chimfine komanso njira zowongolera ma virus.

Pulogalamu ya U.S. yankho ku mliri wa H1N1 wa 2009 unali wolimba komanso wazinthu zingapo, wopitilira chaka chimodzi; Popanda yankho lotere, miyoyo yambiri ikadatayika. Kuphimba kwasiliva kwa mliri waposachedwa wa COVID-19 ndikumvetsetsa komwe dziko lapansi lingapindule nalo poyankha mwamphamvu, kuti ligwiritse ntchito ku miliri yamtsogolo.

Momwe mungakhalire wathanzi

Tikudziwa kuti anthu omwe ali ndi kachilomboka fuluwenza ndi yopatsirana Kwa nthawi yayitali — nthawi zambiri masiku angapo chimfine chimayamba kudwala mpaka masiku asanu mutadwala. Tikudziwanso kuti kachilomboka kangathe kufalikira mlengalenga m'madontho kuchokera kukatsokomola kapena kuyetsemula kwa munthu yemwe ali ndi kachilomboka, kapena ngakhale kukhudza malo omwe madonthowa agwere kenako ndikumakhudza nkhope yanu.

Njira zofunika kuzisamala kuphatikiza omwe aliyense amadziwa bwino chifukwa cha zamakono mliri wa kachilombo ka corona :

  • Gwiritsani ntchito njira zabwino zosamba m'manja ndikugwiritsa ntchito zoyeretsera m'manja
  • Pewani kugwira nkhope yanu
  • Sungani malo ogawana oyera
  • Pewani anthu odwala (ndipo pewani anthu ngati inu mukudwala!)
  • Phimbani chifuwa chanu ndi kuyetsemula kuti musafalikire
  • Pezani katemera

Nyengo Katemera wa chimfine , chaka chilichonse, ndichimodzi mwazinthu zofunikira kwambiri kuti muteteze chimfine. Katemera wa chimfine ndi ena mwa katemera wofikirika kwambiri. Amapezeka kwa ambiri masitolo ogulitsa katundu ndipo nthawi zambiri amakhala ndi inshuwaransi . Katemera wanthawi zonse amalimbikitsidwa kwa anthu onse opitilira miyezi 6, pokhapokha mutalangizidwa ndi omwe amakuthandizani pa zaumoyo. Pali zambiri zambiri zabodza Pazifukwa zopewera kutsekula chimfine, koma ndikofunikira kuti matenda a chimfine atsopano nthawi iliyonse.

ZOKHUDZA: Kodi amayi apakati amatha kutenga chimfine?

Kodi pali katemera wa buku la G4 swine flu?

Katemera wa chimfine wapano sateteza ku G4. Komabe, CDC ikugwira ntchito kuti iwone ngati katemera woteteza ku kachilombo koyambitsa nkhumba amapereka chitetezo ku G4. Ngati sichoncho, CDC iyamba kugwira ntchito ya katemera watsopano wa chimfine yemwe angateteze ku fuluwenza watsopano wa nkhumba.

Ngati 2020 yaphunzitsa dziko lapansi chilichonse, chikuyenera kukhala kufunika kwa ukhondo wosamba m'manja ndi kutalika kwa chikhalidwe. Ngati mukudwala-ziribe kanthu-simukuyenera kupita kuntchito kapena kusukulu, ndipo muyenera kuchepetsa kucheza ndi ena.

Ndikofunika kukhala tcheru ndi ma virus atsopano omwe angathe kuyambitsa mliriwu. Zomwe takumana nazo ndi mliri wa H1N1 wa 2009 ndipo pano ndi mliri wa COVID-19 wakhazikitsa maziko olimba pakumvetsetsa momwe zinthu zingakwere mofulumira, komanso zomwe zakhala zikugwira ntchito komanso zomwe sizinagwire ntchito poyankha. Ngakhale zambiri zomwe zilipo pa G4 swine flu sizokwanira kuchititsa mantha kwathunthu, sitingakhale ndi masomphenya ndi coronavirus ndipo tiyenera kupitiliza kudziwa kuwopsa kwa mitundu yatsopano ya matenda opatsirana.
