Masayendisiti paDe Montfort University (DMU) muLeicester vakayambira kuti hutachiona hwakafanana nehutachiona hunokonzera Covid-19 hunogona kurarama nembatya uye huchipararira kune dzimwe nzvimbo kwemaawa anosvika makumi manomwe nemaviri.
Muongororo yakaitwa pakuongorora maitiro anoita coronavirus pamhando nhatu dzemachira anoshandiswa zvakanyanya muindasitiri yehutano, vaongorori vakaona kuti zviratidzo zvacho zvinogona kuramba zvichitapukira kwemazuva matatu.
Vachitungamirirwa nenyanzvi yezvirwere zvema microbiological Dr. Katie Laird, nyanzvi yezvirwere zvema virology Dr. Maitreyi Shivkumar, uye nyanzvi yezvema postdoctoral Dr. Lucy Owen, tsvakiridzo iyi inosanganisira kuwedzera madonhwe e coronavirus inonzi HCoV-OC43, iyo chimiro chayo uye nzira yekupona yakafanana neye SARS-CoV-2, izvo zvinotungamira kuCovid-19-polyester, polyester donje uye 100% donje.
Zvakabuda zvinoratidza kuti polyester ndiyo njodzi huru yekuparadzira hutachiona. Utachiona hunotapukira huchiripo mushure memazuva matatu uye hunogona kutapurirwa kune dzimwe nzvimbo. Padonje 100%, hutachiona hunogara kwemaawa makumi maviri nemana, nepo padonje repolyester, hutachiona hunorarama kwemaawa matanhatu chete.
Dr. Katie Laird, mukuru weDMU Infectious Disease Research Group, akati: "Pakatanga denda iri, hapana zvakawanda zvaizivikanwa nezvekuti coronavirus inogona kurarama kwenguva yakareba sei pamicheka."
"Zvatakawana zvinoratidza kuti machira matatu anonyanya kushandiswa muhutano ari panjodzi yekuparadzira hutachiona. Kana vanamukoti nevashandi vezvehutano vakatora yunifomu dzavo vachienda nadzo kumba, vanogona kusiya zvimwe zviratidzo zvehutachiona pane dzimwe nzvimbo."
Gore rapera, mukupindura denda iri, Public Health England (PHE) yakaburitsa gwara raitaura kuti mayunifomu evashandi vekurapa anofanira kucheneswa mumaindasitiri, asi kana zvisingaite, vashandi vanofanira kutora mayunifomu acho kuenda nawo kumba kunoachenesa.
Panguva imwe chete, NHS Uniform neWorkwear Guidelines dzinoti zvakachengeteka kuchenesa yunifomu dzevashandi vekurapa kumba chero bedzi tembiricha yaiswa kusvika pa60°C.
Dr. Laird vari kunetseka kuti humbowo hunotsigira chirevo chiri pamusoro apa hwakavakirwa zvakanyanya paongororo mbiri dzekare dzakaburitswa muna 2007.
Mukupindura, akapa zano rekuti mayunifomu ese ehurumende ekurapa acheneswe muzvipatara zvichienderana nemitemo yebhizinesi kana nemakambani ekuwachira mbatya.
Kubva ipapo, akaburitsawo ongororo yemabhuku yakagadziridzwa uye yakazara, achiongorora njodzi yekupararira kwezvirwere mumachira, uye achisimbisa kukosha kwenzira dzekudzivirira hutachiona pakubata machira ekurapa ane utachiona.
"Mushure mekuongorora mabhuku, danho rinotevera rebasa redu nderekuongorora njodzi dzekudzivirira hutachiona hwekuchenesa yunifomu dzekurapa dzakasvibiswa nekoronavirus," akaenderera mberi. "Kana tangoona huwandu hweCoronavirus huripo pamucheka wega wega, tichatarisa pakusarudza nzira yakavimbika yekubvisa hutachiona."
Masayendisiti anoshandisa donje 100%, iro rinoshandiswa zvakanyanya pakurapa, kuita bvunzo dzakawanda vachishandisa tembiricha dzakasiyana dzemvura nenzira dzekuwacha, kusanganisira michina yekuwachisa yemumba, michina yekuwachisa yemumaindasitiri, michina yekuwachisa yemuchipatara yemukati, uye sisitimu yekuchenesa ye ozone (inoshanda zvakanyanya negasi).
Zvakabuda zvakaratidza kuti kusanganiswa kwemvura nekukurunga kwaiitwa nemidziyo yekuwachisa kwakakwanira kubvisa mavhairasi mumichina yese yekuwachisa yakaedzwa.
Zvisinei, apo chikwata chekutsvagisa chakasvibisa machira nemate ekugadzira ane hutachiona (kutevedzera njodzi yekutapurirana kubva mumuromo memunhu ane hutachiona), vakaona kuti michina yekuwachisa yemumba haina kubvisa hutachiona zvachose, uye zvimwe zvisaririra zvakapona.
Kana vakawedzera sipo vobva vawedzera tembiricha yemvura, hutachiona hunopera zvachose. Pakuongorora kuti hutachiona hahuna simba rekupisa chete, zvakabuda zvakaratidza kuti coronavirus inogara mumvura kusvika ku60°C, asi haishande pa67°C.
Zvadaro, chikwata chakadzidza nezvenjodzi yekupararira kwehutachiona, vachisuka mbatya dzakachena nembatya dzine zviratidzo zvehutachiona pamwe chete. Vakaona kuti nzira dzese dzekuchenesa dzakanga dzabvisa hutachiona, uye pakanga pasina njodzi yekuti zvimwe zvinhu zvikanganiswe.
Dr. Laird vakatsanangura kuti: “Kunyangwe tichiona kubva mukutsvagurudza kwedu kuti kunyangwe kushambidzwa kwezvinhu izvi nekupisa kwakanyanya mumuchina wekuwachisa wepamba kunogona kubvisa hutachiona, hazvibvisi njodzi yekuti mbatya dzakasvibiswa dzisiye zviratidzo zve coronavirus pane dzimwe nzvimbo. Dzisati dzasukwa kumba kana mumotokari.
"Iye zvino tava kuziva kuti hutachiona hunogona kugara kwemaawa makumi manomwe nemaviri pamimwe micheka, uye hunogonawo kutapurirwa kune dzimwe nzvimbo."
"Ongororo iyi inosimbisa kurudziro yangu yekuti mayunifomu ese ekurapa acheneswe panzvimbo yacho muzvipatara kana mumakamuri ekuwachira mbatya mumaindasitiri. Nzira idzi dzekuchenesa dzinotariswa, uye vanamukoti nevashandi vekurapa havafanirwe kunetseka nezvekuunza hutachiona kumba."
Nyanzvi dzenhau dzine chekuita neizvi dzinoyambira kuti mayunifomu ekurapa haafanirwe kucheneswa kumba panguva yedenda. Tsvagiridzo inoratidza kuti masisitimu ekuchenesa ozone anogona kubvisa coronavirus kubva muzvipfeko. Tsvagiridzo inoratidza kuti kukwira choko hakugone kuparadzira coronavirus.
Nerutsigiro rweBritish Textile Trade Association, Dr. Laird, Dr. Shivkumar naDr. Owen vakagovana zvavakawana nenyanzvi dzeindasitiri muUnited Kingdom, United States neEurope.
"Mhinduro yacho yaive yakanaka kwazvo," akadaro Dr. Laird. "Masangano ekugadzira machira nekuwacha mbatya pasi rese ari kushandisa ruzivo rwakakosha mumitemo yedu yehutano yekuchenesa mari kudzivirira kupararira kwekoronavirus."
David Stevens, mukuru weBritish Textile Services Association, sangano rekutengeserana muindasitiri yemabasa ekuchengetedza machira, akati: "Mumamiriro ezvinhu edenda, tine kunzwisisa kwakakosha kwekuti machira haasi iwo anonyanya kukonzera kupararira kwecoronavirus."
"Zvisinei, hatina ruzivo nezvekugara zvakanaka kwemavhairasi aya mumhando dzakasiyana dzemachira uye nzira dzakasiyana dzekuwacha. Izvi zvakaita kuti pave nemamwe mashoko asina kururama uye mazano ekuwacha akawandisa."
"Takanyatsoongorora nzira nemaitiro ekutsvagisa anoshandiswa naDr. Laird nechikwata chake, uye takaona kuti tsvakiridzo iyi yakavimbika, inogona kudzokororwa uye inogona kudzokororwa. Mhedziso yebasa iri rakaitwa neDMU inosimbisa basa rakakosha rekudzora kusvibiswa - kungave mudzimba dzichiri munzvimbo yemaindasitiri."
Pepa rekutsvagisa iri rakabudiswa muOpen Access Journal of the American Society for Microbiology.
Kuti vaite tsvakiridzo yakawanda, timu iyi yakashandawo pamwe chete nechikwata cheDMU chezvepfungwa pamwe neLeicester NHS Trust University Hospital pachirongwa chekuferefeta ruzivo nemaitiro evanamukoti nevashandi vezvekurapa pakuchenesa mayunifomu panguva yedenda reCovid-19.
