Isebenza njani i-Airborne Transmission?
Xa umntu ethimla, ekhohlela, ehleka, okanye ekhupha umoya ngandlela thile, ukudluliselwa komoya kwenzeka. Ukuba umntu une-covid-19 kunye ne-omicron, nokuba zezinye izifo zokuphefumla, esi sifo sinokudluliselwa ngamathontsi. Iibhaktheriya okanye iintsholongwane ezidluliselwa kakhulu ngamathontsi amancinci okuphefumla.
Ukuvezwa kumathontsi aveliswa kukukhwehlela nokuthimla kwabantu abasulelekileyo okanye ukudibana neendawo ezinethontsi (iifomite) kuye kwabonwa ngokubanzi njengeendlela eziphambili zokudlulisela izifo zokuphefumla. Ukudluliselwa komoya ngokuqhelekileyo kuchazwa njengokubandakanya ukuphefumla ii-aerosols ezisulelayo okanye "ii-nuclei zethontsi" ezincinci kune-5 μm kwaye ikakhulu kumgama we->1 ukuya kwi-2 m ukusuka kumntu osulelekileyo, kwaye olo kudluliselwa kucingelwa ukuba lufanelekile kuphela kwizifo "ezingaqhelekanga". Nangona kunjalo, kukho ubungqina obuqinileyo obuxhasa ukudluliselwa komoya kweentsholongwane ezininzi zokuphefumla, kubandakanya i-severe acute respiratory syndrome coronavirus (SARS-CoV), i-Middle East respiratory syndrome (MERS)–CoV, i-influenza virus, i-human rhinovirus, kunye ne-respiratory syncytial virus (RSV). Ukulinganiselwa kwemibono yendabuko ye-droplet, i-fomite, kunye nokudluliselwa komoya kwakhankanywa ngexesha lobhubhane we-COVID-19. Ukudluliselwa kwe-droplet kunye ne-fomite kwe-SARS-CoV-2 kuphela akunakuchaza iziganeko ezininzi ezisasazekayo kunye nomahluko ekudluliseleni phakathi kweendawo zangaphakathi nezangaphandle ezibonwe ngexesha lobhubhane we-COVID-19. Impikiswano malunga nendlela i-COVID-19 esasazeka ngayo kunye nokungenelela okufunekayo ukulawula ubhubhane kutyhile imfuneko ebalulekileyo yokuqonda ngcono indlela yokudluliselwa kweentsholongwane zokuphefumla emoyeni, nto leyo eya kuvumela amaqhinga anolwazi olungcono okunciphisa ukudluliselwa kwezifo zokuphefumla.

Ngomhla wesi-8 kuJanuwari, iTshayina ivula kwakhona imida, okokugqibela emva kokuba i-COVID ingekho. Abakhenkethi, oosomashishini, abafundi, nabani na ongena eTshayina akasekho i-qurantine. Iimfuno ze-qurantine ezisisiseko azisekho. Bonke abakhweli bacwangcisa ukuba iTshayina iza kufumana iziphumo zovavanyo lwe-nucleic iiyure ezingama-48, ipasipoti yogonyo yanele. Oku kuthetha ukuba unxibelelwano kunye nokutshintshiselana kuya kwanda kakhulu. Ngaloo ndlela ukuhanjiswa komoya kuya kwanda.
Isicoci somoya singanciphisa ukusasazeka komoya, sincede ekubambeni iintsholongwane, iintsholongwane, size sinciphise amathuba okugula. Izicoci zomoya zinceda kakhulu. Kubalulekile ukufumana isicoci somoya kwigumbi lokuhlala, kwigumbi leenkomfa, kwigumbi leentlanganiso, kwiklabhu, kwindawo yokutyela apho abantu bathetha khona, banxibelelana kakhulu kwaye kukho ukusasazeka okuninzi komoya. Lungisa isicoci somoya emotweni yakho, lungisa isicoci somoya sasekhaya kwigumbi lakho, lungisa isicoci somoya zorhwebo eofisini yakho, lungiselela izicoci zomoya impilo yakho. Phefumla ngendlela esempilweni. Hlala usempilweni kwaye ukhuselekile.
