Ososayensi baseDe Montfort University (DMU) eLeicester baxwayise ngokuthi igciwane elifana nohlobo olubangela i-Covid-19 lingaphila ezingutsheni futhi lisabalale kwezinye izindawo amahora angama-72.
Ocwaningweni oluhlola ukuthi i-coronavirus iziphatha kanjani ezinhlotsheni ezintathu zezindwangu ezivame ukusetshenziswa embonini yezokunakekelwa kwempilo, abacwaningi bathole ukuthi imikhondo ingahlala itheleleka kuze kube yizinsuku ezintathu.
Ngaphansi kobuholi besazi se-microbiologist uDkt. Katie Laird, isazi segciwane uDkt. Maitreyi Shivkumar, kanye nomcwaningi we-postdoctoral uDkt. Lucy Owen, lolu cwaningo lubandakanya ukungeza amaconsi e-coronavirus eyimodeli ebizwa nge-HCoV-OC43, isakhiwo sayo nendlela yokusinda efana neye-SARS- I-CoV-2 ifana kakhulu, okuholela ku-Covid-19-polyester, ukotini we-polyester kanye no-100% ukotini.
Imiphumela ikhombisa ukuthi i-polyester iyingozi enkulu yokusabalalisa leli gciwane.Igciwane elithathelwanayo lisekhona ngemva kwezinsuku ezintathu futhi lingase lidluliselwe kwezinye izindawo.Kukotini ongu-100%, leli gciwane lihlala amahora angama-24, kanti ukotini we-polyester, leli gciwane liphila amahora ayi-6 kuphela.
UDkt. Katie Laird, inhloko ye-DMU Infectious Disease Research Group, uthe: “Lapho lolu bhubhane luqala, kwakuncane okwaziwayo ngokuthi i-coronavirus ingaphila isikhathi esingakanani ezindwangu.”
“Esikutholile kukhomba ukuthi izindwangu ezintathu ezisetshenziswa kakhulu kwezempilo zisengcupheni yokusabalalisa leli gciwane.Uma abahlengikazi nabasebenzi bezokwelapha beyisa imifaniswano yabo ekhaya, bangashiya iminonjana yaleli gciwane kwezinye izindawo. ”
Ngonyaka odlule, ukuphendula lo bhubhane, iPublic Health England (PHE) yakhipha imihlahlandlela ethi imifaniswano yabasebenzi bezokwelapha kufanele ihlanzwe ngokwezimboni, kodwa lapho kungenzeki khona, abasebenzi kufanele bayise imifaniswano bayoyihlanza.
Ngesikhathi esifanayo, i-NHS Uniform and Workwear Guidelines ibeka ukuthi kuphephile ukuhlanza imifaniswano yabasebenzi bezokwelapha ekhaya inqobo nje uma izinga lokushisa libekwe okungenani ku-60°C.
UDkt Laird ukhathazekile ngokuthi ubufakazi obusekela isitatimende esingenhla busekelwe ikakhulukazi ekubuyekezweni kwezincwadi ezimbili eziphelelwe yisikhathi ezishicilelwe ngo-2007.
Ephendula, uphakamise ukuthi yonke imifaniswano yezokwelapha kahulumeni kufanele ihlanzwe ezibhedlela ngokuhambisana nezindinganiso zezohwebo noma ngezingubo zezimboni.
Kusukela lapho, uye washicilela ukubuyekezwa kwezincwadi okubuyekeziwe futhi okuphelele, ehlola ubungozi bezindwangu ekusabalaleni kwezifo, futhi egcizelela isidingo sezinqubo zokulawula ukutheleleka lapho kusingathwa izindwangu zezokwelapha ezingcolile.
"Ngemuva kokubuyekezwa kwezincwadi, isigaba esilandelayo somsebenzi wethu ukuhlola ubungozi bokulawula ukutheleleka kokuhlanza imifaniswano yezokwelapha engcoliswe yi-coronavirus," eqhubeka."Uma sesinqume izinga lokusinda kwe-coronavirus endwangu ngayinye, sizogxila ekutholeni indlela yokugeza ethembeke kakhulu yokususa leli gciwane."
Ososayensi basebenzisa ukotini ongu-100%, okuyindwangu yezempilo esetshenziswa kakhulu, ukwenza izivivinyo eziningi besebenzisa amazinga okushisa ahlukene amanzi nezindlela zokuwasha, okuhlanganisa nemishini yokuwasha yasendlini, imishini yokuwasha yasezimbonini, imishini yokuwasha isibhedlela yasendlini, kanye ne-ozone (igesi esebenza kakhulu) uhlelo lokuhlanza.
Imiphumela yabonisa ukuthi ukunyakazisa nokuhlanjululwa kwamanzi kwakwanele ukususa amagciwane kuyo yonke imishini yokuwasha ehloliwe.
Nokho, lapho ithimba labacwaningi lingcolisa izindwangu ngamathe okwenziwa aqukethe leli gciwane (ukuze lilingise ingozi yokudluliselwa emlonyeni womuntu onaleli gciwane), lathola ukuthi imishini yokuwasha yasendlini ayizange ilisuse ngokuphelele leli gciwane, futhi eminye iminonjana yasinda.
Kuphela lapho bengeza okokuhlanza futhi bephakamisa izinga lokushisa lamanzi, igciwane lisulwa ngokuphelele.Ukuphenya ukumelana kwegciwane ukushisa kuphela, imiphumela ibonise ukuthi i-coronavirus izinzile emanzini afinyelela ku-60 ° C, kodwa ayisebenzi ku-67 ° C.
Okulandelayo, ithimba lahlola ubungozi bokutheleleka ngegciwane, ukuwasha izingubo ezihlanzekile nezingubo ezinemikhondo yegciwane ndawonye.Bathole ukuthi zonke izinhlelo zokuhlanza zazilisusile leli gciwane, futhi kwakungekho bungozi bokuthi ezinye izinto zingcoliswe.
UDkt. Laird wachaza: “Yize sibona ocwaningweni lwethu ukuthi ngisho nokugeza lezi zinto ezisezingeni eliphezulu emshinini wokuwasha wasendlini kungalisusa ngempela leli gciwane, akubuqedi ubungozi bezingubo ezingcolile ezishiya iminonjana ye-coronavirus kwezinye izindawo. .Ngaphambi kokuthi zigezwe ekhaya noma emotweni.
“Manje sesiyazi ukuthi leli gciwane lingaphila amahora angama-72 ezindwangu ezithile, futhi lingadluliselwa kwezinye izindawo.
“Lolu cwaningo luqinisa isincomo sami sokuthi yonke imifaniswano yezokwelapha kufanele igezwe endaweni ezibhedlela noma ezindlini zokuwasha zezimboni.Lezi zindlela zokuhlanza zigadiwe, futhi abahlengikazi nabasebenzi bezokwelapha akudingeki bakhathazeke ngokuletha leli gciwane ekhaya. ”
Ochwepheshe bezindaba abahlobene baxwayisa ngokuthi imifaniswano yezokwelapha akufanele igezwe ekhaya ngesikhathi sodlame.Ucwaningo lukhombisa ukuthi izinhlelo zokuhlanza i-ozone zingasusa i-coronavirus engutsheni.Ucwaningo lukhombisa ukuthi ukugibela ushoki mancane amathuba okuthi kusabalale i-coronavirus.
Ngokusekelwa yiBritish Textile Trade Association, uDkt Laird, uDkt. Shivkumar kanye noDkt. Owen babelane ngalokho abakutholile nochwepheshe bezimboni e-United Kingdom, e-United States naseYurophu.
“Ukusabela kwaba kuhle kakhulu,” kusho uDkt. Laird."Izinhlangano zezingubo zokugqoka nelondolo emhlabeni wonke manje sezisebenzisa imininingwane ebalulekile emikhombandlela yethu yokunakekelwa kwempilo ngokungemthetho ukuvikela ukusabalala kwe-coronavirus."
UDavid Stevens, isikhulu esiphezulu seBritish Textile Services Association, inhlangano yabahwebi bemboni yezokunakekelwa kwendwangu, uthe: “Esimeni esiwubhubhane, sinokuqonda okuyisisekelo ukuthi izindwangu aziyona into ehamba phambili yokudlulisela i-coronavirus.
“Kodwa-ke, asinalo ulwazi mayelana nokuzinza kwalawa magciwane ezinhlotsheni zendwangu ehlukene kanye nezinqubo zokuwasha ezihlukene.Lokhu kuholele elwazini olungamanga oluzungezayo kanye nezincomo zokugeza ngokweqile.
“Sicubungule kabanzi izindlela nezindlela zocwaningo ezisetshenziswa uDkt. Laird nethimba lakhe, sathola ukuthi lolu cwaningo luthembekile, luyakwazi ukukhiqizwa futhi luyakhiqizeka.Ukuphothulwa kwalo msebenzi owenziwe yi-DMU kuqinisa indima ebalulekile yokulawula ukungcoliswa kwemvelo—kungakhathaliseki ukuthi kuseKhaya lisesendaweni yezimboni.”
Iphepha locwaningo lishicilelwe ku-Open Access Journal ye-American Society for Microbiology.
Ukuze kwenziwe olunye ucwaningo, ithimba liphinde lasebenzisana nethimba le-DMU le-psychology kanye ne-Leicester NHS Trust University Hospital emsebenzini wokuphenya ulwazi nezimo zengqondo zabahlengikazi nabasebenzi bezokwelapha ngokuhlanza imifaniswano phakathi nobhadane lwe-Covid-19.
