Lusebenza Njani uThutho lwasemoyeni?
Xa umntu ethimla, ekhohlela, ehleka, okanye ephefumla ngandlela ithile, usasazo oluqhutywa ngumoya luyenzeka. Ukuba umntu wosulelwe yi-covid-19 kunye ne-omicron, kunye nesinye isifo sokuphefumla, esi sifo sinokusasazwa ngamathontsi. Iibhaktheriya okanye iintsholongwane ezidla ngokusasazwa ngamathontsi amancinane okuphefumla.
Ukuvezwa kwamathontsi aphuma ekhohlokhohloni nasekuthimleni kwabantu abosulelekileyo okanye ukudibana neendawo ezingcolisekileyo (iifomites) ziye zabonwa ngokubanzi njengezona ndlela zosulelo lwentsholongwane yokuphefumla. Usasazo ngomoya ngokwesithethe luchazwa njengokubandakanya ukuphefumlelwa kwe-aerosols esosulelayo okanye “i-nuclet nuclei” encinci kune-5 μm kwaye ikakhulu kumgama ongaphezulu kwe-1 ukuya kwi-2 m kude nomntu owosulelekileyo, kwaye usulelo olunjalo kucingelwa ukuba lufanelekile kuphela “ ezingaqhelekanga” izifo. Nangona kunjalo, kukho ubungqina obunamandla obuxhasa ukusasazeka emoyeni kweentsholongwane ezininzi zokuphefumla, kubandakanya ne-acute acute respiratory syndrome (SARS-CoV), Middle East Respiratory Syndrome (MERS)-CoV, virus yomkhuhlane, human rhinovirus, kunye ne-respiratory syncytial virus (RSV) . Imida yeembono zemveli zedroplet, fomite, kunye nokuhanjiswa emoyeni kwakhanyiselwa ngexesha lobhubhani we-COVID-19. Usasazo lwe-droplet kunye ne-fomite ye-SARS-CoV-2 iyodwa ayinakuphendula ngeziganeko ezininzi ezisasazekayo kunye nomahluko wosulelo phakathi kweendawo zangaphakathi kunye nezangaphandle eziqatshelwe ngexesha lobhubhani we-COVID-19. Impikiswano ejikeleze indlela i-COVID-19 esosulela ngayo kwaye loluphi ungenelelo olufunekayo ukulawula ubhubhane lubonakalise isidingo esibalulekileyo sokuqonda ngcono indlela yosasazo ephuma emoyeni yeentsholongwane zokuphefumla, eya kuvumela izicwangciso ezinolwazi olungcono zokunciphisa usulelo losulelo lokuphefumla.

Ngomhla we-8 kaJan, i-China iphinda ivule imida sai ndlela-ntle yokugqibela kwi-zero-COVID. Umkhenkethi, usomashishini, abafundi, nabani na ongena eTshayina akukho quarantine kwakhona. Iimfuno ze-qurantine ezisembindini azisekho mfuneko. Zonke isicwangciso sabakhweli siza eTshayina, iziphumo zovavanyo lwenucleic iiyure ezingama-48, ipasipoti yokugonya yanele. Oku kuthetha unxibelelwano kunye notshintshiselwano lokunyuka kakhulu. Ngaloo ndlela ukuhanjiswa emoyeni kuya kwanda nako.
Isicoci somoya siya kunciphisa usulelo lomoya, sincede ukubamba intsholongwane, ibhaktheriya, emva koko sinciphise ithuba lokugula. Izicoci zomoya zinceda kakhulu. Kuyimfuneko ukufumana indawo yokucoca umoya kwigumbi lokuhlala, igumbi lenkomfa, igumbi leentlanganiso, iklabhu, indawo yokutyela apho abantu bathetha khona, banxibelelana kakhulu kwaye kukho ukuhanjiswa okukhulu emoyeni. Lungiselela isicoci somoya semoto kwisithuthi sakho, lungisa isicoci somoya sasekhaya kwigumbi lakho, lungiselela isicoci somoya sorhwebo kwiofisi yakho, ulungise izicoci zomoya kwimpilo yakho. Phefumla ngokusempilweni. Hlala usempilweni kwaye ukhuselekile.
