Ngaba i-Covid-19 ingasinda kwindawo yobhedu?

 Ubhedu yeyona nto isebenzayo ye-antimicrobial imphezulu.

Kangangamawaka eminyaka, ngaphambi kokuba bazi ngeentsholongwane okanye ngeentsholongwane, abantu bebesazi ngamandla obhedu okubulala iintsholongwane.

Usetyenziso lokuqala olurekhodiweyo lobhedu njengearhente yokubulala usulelo luvela kwi-Smith's Papyrus, eyona xwebhu lwezonyango lwaziwayo embalini.

Ukusukela ngo-1,600 BC, amaTshayina asebenzisa iingqekembe zobhedu njengamayeza okunyanga iintlungu zentliziyo kunye nesisu kunye nezifo zesinyi.

Kwaye amandla obhedu ahlala.Iqela likaKeevil lijonge iireyili zakudala kwisiXeko saseNew York eGrand Central Terminal kwiminyaka embalwa eyadlulayo.Uthi: “Ubhedu lusasebenza kanye njengokuba lwalusenza mhla lwafakwa kwiminyaka eli-100 eyadlulayo."Le nto yomelele kwaye i-anti-microbial effect ayihambi."

Isebenza njani kanye?

Ukwakheka kweathom ethile yeCopper inika amandla awongezelelweyo okubulala.Ubhedu ineelektroni simahla kwiqokobhe yayo yangaphandle orbital elektroni ukuba ngokulula ithatha inxaxheba reactions oxidation-ukunciphisa (nto leyo eyenza isinyithi umqhubi olungileyo).

Xa intsholongwane ihlala phezu kobhedu, ii-ion zidubula i-pathogen njengohlaselo lwemijukujelwa, ithintela ukuphefumla kweseli kunye nokugqobhoza imingxuma kwinwebu yeseli okanye i-viral coating kwaye idala iiradicals zasimahla ezikhawulezisa ukubulala, ngakumbi kwindawo eyomileyo.Okona kubaluleke kakhulu, ii-ion zifuna kwaye zitshabalalise i-DNA kunye ne-RNA ngaphakathi kwebhaktheriya okanye intsholongwane, ukuthintela utshintsho oludala iibhugi ezinkulu ezinganyangekiyo ngamachiza.

Ngaba i-COVID-19 ingaphila kumphezulu wobhedu?

Uphononongo olutsha lufumanise ukuba i-SARS-CoV-2, intsholongwane ebangela ubhubhani we-corona-virus, ayisasuleli kubhedu phakathi kweeyure ezi-4, ngelixa inokuphila kwindawo yeplastiki kangangeeyure ezingama-72.

Ubhedu luneempawu zokulwa neentsholongwane, oku kuthetha ukuba inokubulala iintsholongwane ezinjengeebhaktheriya kunye neentsholongwane.Nangona kunjalo, i-microorganism kufuneka idibane nobhedu ukuze ibulawe.Oku kubhekiselwa kuko "njengokubulala umntu odibana naye."

Ukusetyenziswa kobhedu lwe-antimicrobial:

Esinye sezicelo eziphambili zobhedu kwizibhedlele.Ezona ndawo ziyingozi kakhulu kwigumbi lesibhedlele - iintsimbi zokulala, amaqhosha okufowuna, iingalo zesitulo, itafile yetreyi, igalelo ledatha, kunye ne-IV pole - kwaye endaweni yazo kufakwe izinto zobhedu.

Xa kuthelekiswa namagumbi enziwe ngezinto zemveli, kukho ukunciphisa i-83% yomthwalo webhaktheriya kwiindawo zokuhlala emagumbini anamacandelo obhedu.Ukongeza, amazinga osulelo lwezigulane athotywa ngama-58%.

Izixhobo zobhedu zinokuba luncedo njengendawo yokulwa neentsholongwane ezikolweni, kumashishini okutya, iihotele zeeofisi, iindawo zokutyela, iibhanki njalo njalo.
