Masks anoshanda here? Uye kana zvirizvo, unofanirwa kusvika paN95, mask yekuvhiya, mask yejira kana gaiter?

Kwegore rapfuura nehafu, vaongorori vakagadzira yakawanda marabhoritari, modhi-yakavakirwa uye yekutarisa humbowo pamusoro pekushanda kwemasks. Kune vanhu vazhinji zvave zvakaoma kuti vatarise kuti chii chinoshanda uye chisingaiti.

Ini ndiri mubatsiri purofesa wezvehutano hwezvakatipoteredza sainzi. Ini, zvakare, ndakanetseka nezvemhinduro dzemibvunzo iyi, uye kutanga kwegore rino ndakatungamira chidzidzo chakaongorora tsvakiridzo yekuti ndezvipi zvekushandisa zvakanyanya.

Nguva pfupi yadarika, ndanga ndiri chikamu cheyedzo yakakura kwazvo yakadzorwa kusvika parizvino yekuyedza kushanda kwekupfeka-masiki. Chidzidzo ichi hachisati chaongororwa nevezera asi chakagamuchirwa zvakanaka nevechiremba. Zvatakawana zvinopa humbowo hwegoridhe hunosimbisa tsvakiridzo yapfuura: Kupfeka masiki, kunyanya masiki ekuvhiya, kunodzivirira COVID-19.

Lab uye zvidzidzo zvekucherechedza

Vanhu vanga vachishandisa masiki kuti vazvidzivirire kubva pakubatwa nezvirwere kubva pakatanga kubuda denda reManchurian muna 1910.

Munguva yedenda re coronavirus, tarisiro yanga iri pamasks senzira yekudzivirira vanhu vane hutachiona kubva pakusvibisa mhepo yakavatenderedza - inonzi sosi control. Humbowo hwerabhoritari huchangoburwa hunotsigira pfungwa iyi. Muna Kubvumbi 2020, vaongorori vakaratidza kuti vanhu vakatapukirwa neconavirus - asi kwete SARS-CoV-2 - vakaburitsa shoma coronavirus RNA mumhepo yakavatenderedza kana vakapfeka mask. Zviverengero zvezvimwe zvidzidzo zverabhoritari zvakatsigirawo kushanda kwemasks.

Kunze munyika chaimo, vazhinji vezvechirwere chechirwere vakaongorora mabatiro ekuvharisa uye nemasiki mitemo kuti vaone kana masks achibatsira kunonotsa kupararira kweCOVID-19. Imwe ongororo yekutarisa - zvichireva kuti yanga isiri chidzidzo chinodzorwa nevanhu vakapfeka kana kusapfeka masiki - yakaburitswa mukupera kwa2020 yakatarisa huwandu hwevanhu, kuyedza, kukiya nekupfeka-masiki munyika zana nemakumi mapfumbamwe nematanhatu. Vatsvagiri vakaona kuti mushure mekudzora zvimwe zvinhu, nyika dzine tsika dzetsika kana marongero aitsigira kupfeka-masiki dzakaona vhiki nevhiki pamunhu weconavirus kufa kuri kuwedzera 16% panguva yekubuda, zvichienzaniswa ne62% yekuwedzera vhiki nevhiki munyika dzisina masiki-kupfeka zvimiro.

Yakakura-yakakura randomized mask-kupfeka

Laboratory, yekutarisa uye yekuenzanisira zvidzidzo, zvakagara zvichitsigira kukosha kwemhando dzakawanda dzemasiki. Asi nzira idzi hadzina kusimba semiyedzo mikuru-yakakura yakarongeka pakati pevanhu vose, iyo inoenzanisa mapoka mushure mokunge kupindira kwave kuchiitwa mune mamwe mapoka akasarudzwa uye asina kushandiswa mumapoka ekuenzanisa. Imwe ongororo yakadai yakaitwa muDenmark kutanga kwa2020 yakanga isingaite, asi yaive diki uye yaivimba nevatori vechikamu kuti vazvitaure vakapfeka masiki.

Kubva muna Mbudzi 2020 kusvika Kubvumbi 2021, vandinoshanda navo Jason Abaluck, Ahmed Mushfiq Mobarak, Stephen P. Luby, Ashley Styczynski neni - tichibatsirana zvikuru nevabatsiri muhurumende yeBangladeshi uye tsvakurudzo isina purofiti Innovations for Poverty Action - yakaita hukuru hwakakura inodzorwa muyedzo pa masking muBangladesh. Zvinangwa zvedu zvaive zvekudzidza nzira dzakanakisa dzekuwedzera masiki-kupfeka pasina mvumo, kunzwisisa mhedzisiro yekupfeka-masiki paCOVID-19, uye kuenzanisa masiki emachira nemasiki ekuvhiya.

Chidzidzo ichi chaisanganisira 341, 126 vanhu vakuru mumisha ye600 kumaruwa eBangladesh. Mumisha mazana matatu hatina kusimudzira masiki, uye vanhu vakaramba vakapfeka masiki, kana kuti kwete, sezvavaimboita. Mumisha mazana maviri takakurudzira kushandiswa kwemasks ekuvhiyiwa, uye mumisha zana takakurudzira masiki emachira, tichiyedza nzira dzakasiyana dzekuparidzira muboka rega rega.

Mukufamba kwemavhiki masere, timu yedu yakagovera masiki emahara kumunhu mukuru wega wega mumapoka emasiki kudzimba dzavo, akapa ruzivo nezve njodzi dzeCCIDID-19 uye kukosha kwekupfeka-masiki. Takashandawo nenharaunda nevatungamiriri vezvitendero kutevedzera uye kukurudzira vanopfeka masiki uye vashandi vakahaya kuti vafambe-fambe mumusha uye neruremekedzo kubvunza vanhu vanga vasina kupfeka mask kuti vapfeke. Vashandi vePlainclothes vakanyora kana vanhu vakapfeka masiki nemazvo pamuromo nemhino, zvisizvo kana kuti kwete.

Masvondo mashanu nemapfumbamwe mushure mekutanga chidzidzo, takaunganidza data kubva kune vese vakuru nezvezviratidzo zveCOVID-19 panguva yekudzidza. Kana munhu akataura chero zviratidzo zveCCIDID-19, isu takatora uye kuyedza sample yeropa humbowo hwehutachiona.

Kupfeka mask-kupfeka kwakaderedza COVID-19

Mubvunzo wekutanga ini nevandinoshanda navo waida kupindura waive wekuti kuedza kwedu kwakakonzera kuwedzera kwekupfeka-masiki. Kushandiswa kwemask kanopfuura katatu, kubva pagumi nematatu muzana muboka iro risina kupihwa masiki kusvika makumi mana nemaviri muzana muboka raive. Sezvineiwo, kufambiswa kwemuviri kwakawedzera ne5% mumisha yatakasimudzira masiki.

Mumisha mazana matatu yatakagovera chero rudzi rwemask, takaona kudzikiswa ne9% muCOVID-19 zvichienzaniswa nemisha yatisina kusimudzira masiki. Nekuda kwenhamba shoma yemisha yataisimudzira masiki emachira, hatina kukwanisa kutaura kuti machira kana masiki ekuvhiya aive nani mukuderedza COVID-19.

Isu takanga tine saizi yakakura yakakwana yekuona kuti mumisha yatakagovera masiki ekuvhiya, COVID-19 yakadonha ne12%. Mumisha iyoyo COVID-19 yakadonha ne35% kuvanhu vane makore makumi matanhatu zvichikwira uye 23% kuvanhu vane makore makumi mashanu kusvika makumi matanhatu. Kana tichitarisa zviratidzo zveCCIDID-19 takaona kuti masiki ekuvhiya nemachira zvakakonzera kudzikiswa ne12%.

Humbowo hwehumbowo hunotsigira masiki

Pamberi pechidzidzo ichi pakanga paine kushomeka kwegoridhe-yakajairwa humbowo pakushanda kwemasks kudzikisa COVID-19 muhupenyu hwezuva nezuva. Chidzidzo chedu chinopa humbowo hwakasimba hwepasirese hwekuti masks ekuvhiya anoderedza COVID-19, kunyanya kune vakuru vakuru vanotarisana nehuwandu hwerufu nekuremara kana vakatapukirwa.

Vagadziri vemitemo uye vashandi vehutano hweveruzhinji izvozvi vane humbowo kubva kumarabhoritari, modhi, zvinocherechedzwa uye miyedzo yepasirese inotsigira kupfeka-mask kudzikisa zvirwere zvekufema, kusanganisira COVID-19. Tichifunga kuti COVID-19 inogona kupararira zviri nyore kubva kumunhu kuenda kumunhu, kana vanhu vazhinji vakapfeka masiki mabhenefiti anowedzera.

Saka nguva inotevera iwe uchinetseka kana uchifanira kupfeka mask, mhinduro ndihongu. Masiki ejira anogona kunge ari nani kupfuura chero chinhu, asi masiki ekuvhiya emhando yepamusoro kana masiki ane yakanyanya kusefa kunyatsoshanda uye kukwana zviri nani - seKF94s, KN95s neN95s - ndiwo anonyanya kushanda pakudzivirira COVID-19.
