Matenda a Coronavirus 2019 (COVID-19) ndi matenda opatsirana omwe amayamba chifukwa champhamvu kwambiri ya kupuma kwa coronavirus 2 (SARS-CoV-2).Mlandu woyamba adadziwika ku Wuhan, China, mu Disembala 2019. [7]Matendawa afalikira padziko lonse, zomwe zachititsa kuti pakhale mliri wopitirirabe.[8]

Zizindikiro za COVID-19 zimasinthasintha, koma nthawi zambiri zimaphatikizapo kutentha thupi, chifuwa, kutopa, kupuma movutikira, komanso kutaya fungo ndi kukoma.Kachilombo kamene kamayambitsa COVID-19 kumafalikira makamaka munthu yemwe ali ndi kachilomboka akakhala pafupi[a] ndi munthu wina.[17][18]Tizilombo tating'onoting'ono tokhala ndi kachilomboka timatha kufalikira kuchokera m'mphuno ndi mkamwa mwa munthu yemwe ali ndi kachilomboka akamapuma, kutsokomola, kuyetsemula, kuimba, kapena kulankhula.Anthu ena amatha kutenga kachilomboka ngati kalowa mkamwa, mphuno kapena mmaso mwawo.

Pewani anthu ambiri komanso malo opanda mpweya wabwino

1. Kukhala pagulu la anthu monga m'malesitilanti, mabala, malo ochitira masewera olimbitsa thupi, kapena malo owonetsera makanema kumakuyikani pachiwopsezo chachikulu cha COVID-19.

2. Pewani malo amkati omwe sapereka mpweya wabwino kuchokera panja momwe mungathere.

3. Ngati muli m’nyumba, bweretsani mpweya wabwino potsegula mawindo ndi zitseko, ngati n’kotheka.

Ukhondo ndi mankhwala

1. Tsukani NDI kupha tizilombo tomwe timagwira pafupipafupi tsiku lililonse.Izi zikuphatikizapo matebulo, zitseko, zosinthira magetsi, makatatala, zogwirira, madesiki, mafoni, kiyibodi, zimbudzi, faucets, ndi masinki.

2. Ngati malo ali akuda, ayeretseni.Gwiritsani ntchito zotsukira kapena sopo ndi madzi musanaphe tizilombo.

3. Kenako, gwiritsani ntchito mankhwala ophera tizilombo m’nyumba.Gwiritsani ntchito zinthu za EPA's List N: Disinfectants for Coronavirus (COVID-19) chithunzi chakunja molingana ndi mayendedwe olembedwa ndi opanga.

Kutsekereza kwa mzere wamba ndiko kuwononga mamolekyu a DNA kapena RNA ya tizilombo toyambitsa matenda kudzera mu kuwala kwa ultraviolet, kuti mabakiteriya amafa kapena sangathe kuberekana.Kuti akwaniritse cholinga chotsekereza.Mphamvu yeniyeni ya bactericidal ndi UVC ultraviolet, chifukwa C-band ultraviolet ndiyosavuta kutengeka ndi DNA ya zamoyo, makamaka UV ya 260-280nm ndiyo yabwino kwambiri.

Ultraviolet imawononga DNA ndi RNA ya tizilombo tating'onoting'ono, kuwapangitsa kutaya mphamvu zobereka ndi kufa, ndikukwaniritsa zotsatira za kupha tizilombo toyambitsa matenda ndi kutseketsa.

Monga wopanga zowunikira zaka zopitilira khumi zakuwunikira kwa LED, Aina Yowunikira imayenderana ndi chitukuko cha nthawi ndikukwaniritsa zosowa zapadziko lonse lapansi, ndipo yapanga nyali zosiyanasiyana zothana ndi majeremusi kuti athe kuthana ndi mliri wapadziko lonse lapansi.Akhoza kupha mitundu yonse ya mabakiteriya ndi mavairasi mu nthawi yochepa kwambiri ndipo angagwiritsidwe ntchito pa foni yam'manja, chigoba, makina a makompyuta, zipangizo, mphete zala, mkanda, botolo la unamwino, zovala ndi zolemba zilizonse.Kuphatikiza apo, tapanga zoziziritsa kukhosi zoziziritsira ndikuyeretsa mpweya m'malesitilanti, malo odyera, mipiringidzo, malo ogulitsira, masukulu, nyumba, zipatala ndi malo ena am'nyumba.
