Uyakhumbula uloyiko lobhubhane we-COVID ekuqaleni kuka-2020? Xa izikhululo zokuhlamba izandla kunye nezicoci zezandla zazikho kuyo yonke indawo, kwaye abantu babesoyika nokuchukumisa izibambo zomnyango? Sonke sasicinga ukuba esi sifo sinokusasazeka kuphela ngumntu okhohlelayo, othimla, okanye ochukumisa indawo enentsholongwane kuyo. Kodwa, isiganeko esincinci satshintsha zonke iinkolelo zethu zokuqala. Yiloo nto sithetha ngayo namhlanje.
Isiganeko esatshintsha yonke into
Oku kwenzeke ngoMatshi 2020, eWashington, eMelika. Amalungu angama-61 ekwayala ebizwa ngokuba yi-'Skagit Valley Chorale' ajoyina uqheliso lweeyure ezimbini ezinesiqingatha. Balandela yonke imiqathango yezempilo ngelo xesha. Akukho mntu wachukumisa omnye umntu, bagcina umgama omalunga neemitha ezimbini, kwaye basebenzise i-sanitizer yezandla kakuhle.
Kodwa okumangalisayo kukuba, kwiiveki ezimbalwa nje, abantu abangama-52 kwaba bantu bangama-61 babesele benesifo se-COVID-19! Abaninzi kwafuneka bangeniswe esibhedlele, kwaye ngelishwa, ababini basweleka.
Ekuqaleni izazinzulu zamangaliswa. Wonke umntu wazibuza, "Kwenzeke njani oku?" Babekude kakhulu, babengathintani, ngoko ke kwenzeka njani ukuba abantu abaninzi kangaka bagule ngaxeshanye?
Kulapho ke isazinzulu sathi, "Bekukho into enye kuphela eyayisabelwana ngayo ngumntu wonke kuloo gumbi. Ngumoya lowo," kwaye "Akukho mathandabuzo ukuba isifo sasasazeka ngaloo moya."
Esi siganeko sasibaluleke kakhulu esitshintshe izinto ezininzi esasizicinga malunga nobhubhane weCovid.
Ngoko ke, ngaba besisoloko sicinga ngendlela engafanelekanga ixesha elide kangaka? Umbono omdala 'wethontsi'
Enyanisweni, kangangeminyaka elikhulu okanye ngaphezulu, iingcali zempilo bezikholelwa ukuba izifo zokuphefumla ezifana nomkhuhlane kunye ne-influenza zisasazeka ikakhulu ngamathontsi amakhulu, anzima. Ngamafutshane, amathontsi amathe akhutshwa xa umntu ekhohlela okanye ethimla.
Ngokwale mbono, esi sifo siphuhla ukuba:
- Ufanele uhlale ukufutshane kakhulu xa umntu ogulayo ekhohlela okanye ethimla.
- Okanye, ungagula ukuba uchukumisa umphezulu (njengetafile okanye isitshixo somnyango) onamaconsi amakhulu uze uchukumise impumlo yakho, umlomo, okanye amehlo ngeso sandla sinye.
Le ngcinga indala (iDroplet Dogma) yiyo loo nto sacetyiswa ukuba sihlale umgama oziimitha ezi-6 size sisule yonke into ngesibulali-ntsholongwane ngexesha leentsuku zokuqala zeCovid.
Kodwa ngoko kwenzekayo kuloo kwayara, izazinzulu zaqonda ukuba kukho isiphene esikhulu kweli bali ndaweni ithile. Kufuneka kubekho indlela efihlakeleyo yokusasazeka kwesi sifo.
'Iconsi' kunye 'ne-aerosol' - yintoni umahluko?
Kulapho sifumana khona igama elitsha - 'i-aerosol'. Oku kubaluleke kakhulu ukukuqonda. Cinga ngebhotile yokutshiza. Xa uyitshiza, amathontsi amakhulu amanzi awela emhlabeni, kwaye kukwakho namasuntswana amanzi amancinci, angabonakaliyo ahamba emoyeni, njengenkungu, akunjalo? Yiyo loo nto kunjalo.
'Amaconsi' afana nala maconsi makhulu. 'Ii-Aerosols' zifana nala masuntswana mancinci ahamba emoyeni.
Makhe sijonge umahluko phakathi kwezi zimbini ngale ndlela.
| Uphawu | Amathontsi amakhulu (Amathontsi) | Amasuntswana amancinci kakhulu (ii-Aerosols) |
|---|---|---|
| Ubungakanani | Inkulu kakhulu (nangona ingabonakali emehlweni) | Incinci kakhulu (njengomsi) |
| Impembelelo kumxhuzulane | Iwela emhlabeni ngokukhawuleza (kwimizuzwana/imizuzu embalwa) ngenxa yobunzima bayo. | Ngenxa yokuba ilula kakhulu, ingadada emoyeni imizuzu, mhlawumbi iiyure. |
| Umgama wohambo | Umgama omfutshane (malunga ne-1-2 yeemitha). | Ingasasazeka nakwigumbi lonke. |
| Indlela esasazeka ngayo | Ngokungena ngqo emzimbeni xa umntu ekhohlela okanye ethimla kufutshane. | Xa umntu onentsholongwane ephefumla, ethetha, okanye ecula, ingena emoyeni ize iphefumle. |
Xa amalungu ekwayala ayecula, la masuntswana mancinci (ii-aerosols) akhululwa emoyeni wawo.Igumbi lonke kufuneka ukuba lalizele ngumoya. Nangona babekude kakhulu, bonke babephefumla umoya ofanayo, ngoko phantse wonke umntu wagula. Oku kubizwa ngokuba yi -airborne transmission .
Indlela ulwazi olutsha olutshintshe ngayo ubomi bethu
Ngokufumana oku, iindlela esasizisebenzisa ukulawula ubhubhane zatshintsha ngokupheleleyo.
Ukusuka ekusuleni iindawo ukuya ekucingeni ngomoya
Ekuqaleni, sasicinga ukuba ukusula imigangatho, iitafile, kunye nezibambo zomnyango yeyona nto ibalulekileyo. Kodwa emva kokuqonda ukuba kuphuma emoyeni, safunda ukuba kukho into ebaluleke nangakumbi. Kwaye oko kukungenisa umoya kakuhle.
Ngamafutshane, ukugcina iingcango neefestile zivuliwe nokusebenzisa ifeni ukuhambisa umoya kunciphisa ukuxinana kwamasuntswana eentsholongwane kwindawo enye.
Ixabiso lokwenyani lemaski
Ekuqaleni, iimaski zazinxitywa ukuze kuthintelwe amathontsi amakhulu esasiwakhohlela. Kodwa kamva kwafunyaniswa ukuba imaski elungileyo efana ne-N95 inokucoca kwanala masuntswana amancinci eentsholongwane (ii-aerosols) ahamba emoyeni. Ke ngoko, ukubaluleka kwemaski kwanda nangakumbi.
Olu lwazi luza kusinceda kakhulu ekuzikhuseleni kungekuphela nje kwiCovid, kodwa nakwisifo sokuphefumla esiza kubakho kwixesha elizayo.
Umyalezo Wokuya Ekhaya
- Izifo zokuphefumla ezifana ne-COVID-19 zinokusasazeka ngamathontsi amakhulu akhutshwa xa umntu ekhohlela, kunye namasuntswana amancinci kakhulu (ii-aerosols) ahamba emoyeni xa ethetha okanye ephefumla.
- Umngcipheko wokusasaza intsholongwane uphezulu kwiindawo ezivaliweyo (amagumbi, iibhasi). Ngoko ke, kubaluleke kakhulu ukugcina umoya uvulekile , oko kuthetha ukugcina iifestile zivuliwe.
- Ukunxiba iimaski kunceda ekukhuseleni amathontsi amakhulu kunye namasuntswana amancinci ahamba emoyeni.
- Isayensi ayitshintshi. Ulwazi lwethu nokuqonda kwethu kuyatshintsha njengoko ubungqina obutsha bufumaneka. Iindyikityha zingumzekelo obalaseleyo waloo nto.
