Ukhe weva ingxolo eninzi kutsha nje malunga nokukhanya kwe-UV, kubandakanya ukukhanya kwelanga, kwaye nokuba ingazitshabalalisa na iintsholongwane ezifana ne-coronavirus entsha, ebangela i-COVID-19.
Asiyiyo yonke i-hype. Ngapha koko, kukho ubungqina obulungileyo bokuba ukukhanya kwe-UV kuluhlu lwe-"C", ekwabizwa ngokuba yi-UVC, inokubulala le ntsholongwane. Kodwa oko akuthethi ukuba kufuneka ubaleke kwaye uthenge enye yeebhokisi ze-UV okanye ii-wands ezibonakala ngathi zivela kuyo yonke indawo. Yile nto ekufuneka uyazi.
Sisebenza njani isibane seUV?
Kangangeminyaka, izibhedlele kunye neelebhu zisebenzisa ukukhanya kwe-ultraviolet (UV) ukubulala iintsholongwane izixhobo kunye nomgangatho. Isebenza ngokuguqula imathiriyeli yemfuza yeentsholongwane (ezaziwa ngokuba yiDNA kunye neRNA yazo). Kodwa ekuhambeni kweminyaka, uphando luye lwabonisa ukuba kwiintlobo ezintathu eziphambili zokukhanya kwe-UV, i-UVA, i-UVB, kunye ne-UVC, I-UVC ibonakala iyeyona isebenzayo.
Kutshanje, uphando oluvela kwiYunivesithi yaseColumbia lufumanise ukuba ukukhanya kwe-UVC kubambe isithembiso ekunqandeni ukusasazeka kwecoronavirus. Uphononongo, olupapashwe ngo-Epreli ka-2020 njenge-preprint kwi-Virology, lwafumanisa ukuba ukukhanya kwe-UVC inokunceda ukuphelisa iindidi ezimbini zee-coronavirus zamaxesha onyaka ezisoloko zisemva kwengqele eqhelekileyo. Abaphandi ngoku bayayivavanya ngokuchasene naleyo ibangela i-COVID-19.
Nangona uphando lusandulela, iziphumo zangaphambili zibonisa ukuba ukukhanya kwe-UVC inokwenza intsholongwane yomkhuhlane we-H1N1 emoyeningokunjalo ezinye iibhaktheriya ezingeva yeza. Oku kuthetha ukuba unokuba namandla okuthintela ukusasazeka kwe-COVID-19.
Olunye uphononongo lokuqala lwaselabhoratri, olwapapashwa ngo-Epreli ka-2020 kwi-medRxiv, lwafumanisa ukuba xa iziqwenga zelaphu zemaski ezi-N95 kunye nentsimbi engatyiwayo zaye zangcoliswa yinoveli coronavirus emva koko zavezwa kwisibane se-UVC yesibhedlele, intsholongwane yabulawa kuyo yomibini iyure. Nangona kunjalo, uphononongo lusajongwa kwakhona, ngoko ke akufuneki luthathwe njengexabiso lobuso okwangoku.
Ingxaki ngeemveliso zabathengi be-UVC
Unikwe olu phando, unokuba ucinga nzulu ngokuthenga enye yeemveliso zokukhanya ze-UVC onokuzifumana kwi-Intanethi njengendlela yokucoca yonke into ukusuka kwi-smartphone yakho ukuya kwikhawuntari yakho yasekhitshini.
Kodwa i-FDA ikhuphe isaziso ngokuchasene nabo ngoFebruwari 2020, ikhumbuza abantu ukuba ezi zixhobo azikavunywa yi-FDA, kwaye akucaci ukuba zikhuselekile kwaye zisebenza kangakanani na.
Umceli mngeni omkhulu kuninzi lwabo kukuba akukho ndlela yokwazi ngokuqinisekileyo ukuba bahambisa idosi enkulu ngokwaneleyo yokukhanya kwe-UVC kumphezulu ofuna ukuwubulala iintsholongwane, nokuba sisigqubuthelo semaski, ifowuni, okanye icountertop.
Nangona uninzi lweemveliso zibonelela ngamaza obude, obufanele ukuba malunga nama-nanometers angama-260 (nm), uninzi aluboneleli nge-irradiance, ekuxelela ukuba kuya kuthatha ixesha elingakanani ukubulala i-coronavirus. Akukho sizathu sokuthenga i-wand ye-UV ukuba oko kuthetha ukuba kuya kufuneka uyihambise kancinci kwifowuni yakho kangangeyure.. Kwaye ukuba i-irradiance iphezulu, inokonakalisa ulusu kunye namehlo.
Ukuba ufuna ukuzama, ndincoma utyalo-mali kwibhokisi ye-UVC, apho ubeka khona ifowuni yakho okanye ezinye izinto, njengamakhadi okuthenga ngetyala, izitshixo, okanye ukubukela, kwaye uzishiye apho malunga nemizuzu eyi-10. Musa ukusebenzisa amalaphu okanye izinto ezirhabaxa ezifana nephepha okanye ikhadibhodi, njengoko ukukhanya kwe-UV kunokubangela izithunzi kwizinto ezingaqinanga.
Enye into enokwenzeka sisicoci se-UV kwii-smartphones Isepha yefowuni 3 (I-96 €), ebanga ukuba inobude be-UVC obungama-254 nm, ekuluhlu oluchanekileyo lokubulala ii-coronavirus. Uphononongo lukaJanuwari 2018, olupapashwe kwiJenali yeAmerican Association for Laboratory Animal Science, yafumanisa ukuba isixhobo seFoniSoap sasi Isebenza ngakumbi kunokucoca isibulali-ntsholongwane okanye isitshizi esine-70 yepesenti yotywala.
Nangona ii-UVCs zisebenza ngokukhawuleza nangokuthembeke ngakumbi kwiindawo ezingenazo iintsholongwane njengeglasi, iplastiki, intsimbi, kunye nemithi evanisiweyo, kunokuba lula, ngokukhawuleza, kwaye kukhuseleke ngakumbi ukuzicoca ngesibulali-ntsholongwane sasekhaya, kunokuxhomekeka kwi-wand ye-UV.
Ngaba ukukhanya kwelanga kusebenza ukubulala iintsholongwane?
Ukuba iimveliso ze-UVC zinokuba yinkcitho yexesha kunye nemali, unokuzibuza ukuba kungcono ukufihla kunye nokutshisa ilanga, kuba ukukhanya kwelanga kuqulethe imitha ye-UV.
Kodwa ukukhanya kwe-UVC okuvela elangeni kuthintelwe ngumoya woMhlaba. Xa uphuma phandle ngemini enelanga, isibane se-UV esikubethayo yi-UVA kunye ne-UVB ethile, kwaye aba bafana abazitshabalalisi ii-coronavirus ngokukhawuleza.
Oko kuthethiweyo, kukho ubungqina obuthile bokuba ukukhanya kwelanga kuyasebenza ngokuchasene ne-coronavirus entsha. Uphando lokuqala, olwenziwa liSebe lezoKhuseleko lweLizwe lase-US, lwafumanisa ukuba ukukhanya kwelanga okufanisiweyo (ilingana nelanga lasemini ngemini enelanga) akhukulise amathontsi e-COVID-19 emva kwemizuzu emithathu zombini kwiindawo ezingenazo iintunja kunye nasemoyeni.
Kodwa loo nto ayithethi ukuba kufuneka ulahlele kude emoyeni kweli hlobo. Ukuba ungaphandle kwaye uphefumle amathontsi omntu owosulelekileyo okufutshane nawe, usengagula.
Eso sesinye sezizathu ezibangela ukuba kukholelwe oko amaqondo obushushu aphezulu kunye nemitha ye-UV ayikunciphisi ukusasazeka kwe-COVID-19, ngokutsho kophononongo luka-Aprili 2020 olupapashwe kwi-European Respiratory Journal. Ngoko ukuba ufuna ukuzikhusela kwimitha, yenze, kodwa faka i-sunscreen, gqoka imaski kwaye uhlale ubuncinane iimitha ezimbini kude nabo bonke abantu abakujikelezile.
