UVC Virus Killers: Cov Teeb Hluav Taws Xob thiab Far UVC
Cov teeb hluav taws xob tua kab mob tau dhau los ua ntau dua li cov neeg tua kab mob UVC raws li qhov tshwm sim ntawm COVID-19 kis thoob qhov txhia chaw, uas qhia txog qhov tsim nyog ntawm kev siv cov txheej txheem tiv thaiv kab mob thiab tswj tau zoo (IPC). Tus kab mob SARS-CoV-2 uas ua rau COVID-19 yuav raug tua nrog kev ua tau zoo los ntawm kev siv thev naus laus zis los ntawm ultraviolet (UV), uas yog cov txheej txheem IPC muaj peev xwm.
Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb, WHO, tau tshaj tawm txog 761,402,282 tus neeg mob uas tau lees paub los ntawm COVID-19 txij li lub Peb Hlis 29, 2023, nrog rau 6,887,000 neeg tuag hauv 229 lub tebchaws thiab thaj chaw, thiab 102,697,566 tus neeg mob uas tau lees paub ntawm COVID{{13} } nrog 1,117,054 tus neeg tuag hauv Tebchaws Meskas.
Inactivation ntawm tus kab mob UVC thiab muaj txiaj ntsig los tiv thaiv kev kis tus kab mob
Cov lag luam thiab cov neeg siv khoom tuaj yeem kawm paub ntau ntxiv txog kev tiv thaiv tus kab mob UV teeb thiab nws muaj txiaj ntsig zoo li cas ntawm kev txwv tsis pub kis tus kab mob los ntawm kev mus xyuas FDA lub vev xaib. UVC germicidal teeb yog tsim los rau emit UVC hluav taws xob ntawm lub wavelength kom zoo, uas tau siv rau ntau xyoo los ua kom zoo tshuaj tua kab mob ntawm qhov chaw, dej, thiab cua. Beta coronaviruses thiab ntau lwm yam kab mob, suav nrog cov kab mob ua rau tuberculosis, txhua tus raug rhuav tshem los ntawm UV-C lub teeb.
MERS, SARS, and SARS-CoV-2 Viruses are Destroyed by UV-C Light
Txawm hais tias tus mob coronaviruses paub tias kis tau rau tib neeg thiab tsiaj txhu, lawv yog tsev neeg dav ntawm cov kab mob uas feem ntau ua rau mob ua pa me me rau tib neeg. Lawv tuaj yeem kis tau ntau zaus hauv cov tsiaj, tab sis yog tias muaj kab mob sib kis tshwm sim, lawv tuaj yeem txav mus rau tib neeg thiab txuas ntxiv mus. Vim hais tias ntawm qhov chaw protrusions uas zoo li lub kaus mom thiab muab tus mob coronaviruses lawv lub npe.
Txawm hais tias tus kab mob ua pa hnyav heev (SARS-CoV), zoo li tus kab mob SARS uas tuag taus xyoo 2002 thiab Middle East Respiratory Syndrome coronavirus (MERS-CoV) hauv xyoo 2012, tuaj yeem ua rau mob hnyav, qee yam kab mob coronavirus tuaj yeem tsim cov kab mob xws li mob khaub thuas. Lwm tus kab mob uas ua rau COVID-19 yog SARS-CoV-2, lossis tus kab mob ua pa hnyav heev.
Thaum siv ntawm txoj cai wavelength thiab koob tshuaj, ultraviolet lub teeb viral inactivation muaj kev vam meej nyob rau hauv kev tshem tawm cov kev hem thawj los ntawm tus mob coronaviruses, suav nrog tus kab mob SARS-CoV-2. Inactivating SARS-CoV-2 reproduction nrog UV-C irradiation yog qhov ua tau zoo heev, raws li kev tshawb fawb tshawb fawb; Tus kab mob UV cov tshuaj tiv thaiv yog nyob ntawm ob qho tib si tus kab mob qhov concentration thiab UVC koob tshuaj. Cov kev tshawb pom ntawm qhov kev tshawb fawb no thiab ntau lwm yam qhia tau hais tias muaj kev cuam tshuam rau UVC teeb rau SARS-CoV-2 tus kab mob no li cas.
Cov kab mob thiab lwm yam kab mob phem raug tua los ntawm UVC lub teeb.
Cov txiaj ntsig hauv qab no ntawm kev tshawb fawb txog UVC viral inactivation tiv thaiv ntau yam kab mob txaus ntshai tau tshaj tawm los ntawm Kev Pabcuam Txog Kev Noj Qab Haus Huv hauv xyoo 2020:
Influenza A H1N1 txo qis ntawm 99.999 feem pua
Txo tus kab mob SARS-CoV-2 los ntawm 99.999 feem pua
Txo tus kab mob poliovirus LSc 1 los ntawm 99.99 feem pua
99.99% txo qis hauv Methicillin-Resistant Staphylococcus Aureus (MRSA)
6 hom Salmonella sib txawv, 99.99 feem pua tsawg
Thaum siv cov teeb pom kev zoo UVC tshuaj tua kab mob, koob tshuaj, thiab qhov chaw (xws li kab-ntawm-pom tshuaj tua kab mob ntawm qhov chaw tsis muaj cov khib nyiab uas yuav cuam tshuam rau UV inactivation tshwm sim), UV tua kab mob ua tau zoo heev. Rau qhov ua tau zoo tshaj plaws, cov txheej txheem ntxuav phau ntawv yuav tsum tau siv ua ke rau kev kho mob UV teeb.
Disinfection ntawm UVC Virus nyob rau saum npoo, dej, thiab cua
Feem ntau tailored los tsim wavelengths ntawm precisely 254 nm, UVC germicidal teeb tau pom tias yuav ua tau zoo heev nyob rau hauv kev rhuav tshem cov kab mob los ntawm kev nkag mus rau lawv DNA. Far UVC teeb tau dhau los ua ntau dua vim tias lawv lub zog zoo tiv thaiv kab mob thiab kev nyab xeeb nyob ib puag ncig tib neeg. Standard germicidal UVC teeb yuav pom nyob rau hauv HVAC systems, sab sauv chav tsev ultraviolet germicidal irradiation (UVGI) systems, thiab lwm yam khoom siv tshuaj tua kab mob xws li UVC robots programmed khiav ib ncig ntawm cov neeg mob nyob rau hauv lub tsev kho mob cov tsev. Cov teeb no yuav tsum tau siv rau hauv qhov chaw khoob.
Yuav kom ua tiav cov kab mob zoo, nws yog ib qho tseem ceeb rau kev koom tes nrog tus kws tsim teeb pom kev zoo ultraviolet vim tias tsis yog tag nrho UVC germicidal teeb tau sib npaug.
