Uyakhumbula ukwesaba ubhubhane lwe-COVID ekuqaleni kuka-2020? Ngesikhathi iziteshi zokugeza izandla kanye nezihlanzi-zandla zazikhona yonke indawo, futhi abantu besaba ngisho nokuthinta izibambo zeminyango? Sonke sasicabanga ukuthi lesi sifo singasakazwa kuphela ngumuntu okhwehlelayo, othimulayo, noma othinta indawo enegciwane kuso. Kodwa, isigameko esincane sashintsha zonke izinkolelo zethu zokuqala. Yilokho esikhuluma ngakho namuhla.
Umcimbi owashintsha konke
Lokhu kwenzeka ngoMashi 2020, eWashington, e-USA. Amalungu angu-61 ekwaya ebizwa ngokuthi i-'Skagit Valley Chorale' ajoyina umkhuba wamahora amabili nesigamu. Alandela yonke imihlahlandlela yezempilo ngaleso sikhathi. Akekho othinte omunye umuntu, wagcina ibanga elingamamitha amabili, futhi wasebenzisa i-sanitizer yezandla kahle.
Kodwa ngokumangazayo, phakathi namasonto ambalwa, abangu-52 kulaba bantu abangu-61 base bethole i-COVID-19! Abaningana kwadingeka bangeniswe esibhedlela, futhi ngeshwa, ababili bashona.
Ososayensi baqale bamangala. Wonke umuntu wazibuza, "Kwenzeke kanjani lokhu?" Babeqhelelene kakhulu, babengathintani, pho kwenzeka kanjani ukuthi abantu abaningi kangaka bagule ngesikhathi esisodwa?
Yilapho usosayensi athi khona, "Kwakukhona into eyodwa kuphela eyayihlanganyelwa yiwo wonke umuntu kulelo gumbi. Lowo kwakuwumoya ," nokuthi "Akungabazeki ukuthi lesi sifo sasakazeka ngalowo moya."
Lesi sigameko sasiyisenzakalo esibalulekile esashintsha izinto eziningi esasizicabanga ngobhubhane lwe-Covid.
Ngakho-ke, ingabe besilokhu sicabanga kabi isikhathi eside kangaka? Umbono omdala 'weconsi'
Eqinisweni, eminyakeni eyikhulu edlule noma ngaphezulu, ochwepheshe bezempilo bebekholelwa ukuthi izifo zokuphefumula ezifana nomkhuhlane kanye nomkhuhlane zisakazeka ikakhulukazi ngamaconsi amakhulu, asindayo. Kalula nje, amaconsi amathe akhishwa lapho umuntu ekhwehlela noma ethimula.
Ngokwalo mbono, lesi sifo sikhula uma:
- Kufanele uhlale useduze kakhulu uma umuntu ogulayo ekhwehlela noma ethimula.
- Noma, ungagula uma uthinta indawo (njengetafula noma i-doorknob) enamaconsi amakhulu bese uthinta ikhala lakho, umlomo, noma amehlo akho ngaleso sandla esifanayo.
Le nkolelo endala (i-Droplet Dogma) yingakho selulekwa ukuthi sihlale ibanga elingamamitha ayi-1.5 futhi sisule yonke into ngesibulali-magciwane ezinsukwini zokuqala ze-Covid.
Kodwa ngalokho okwenzeke kuleyo kwaya, ososayensi baqaphela ukuthi kwakukhona iphutha elikhulu kule ndaba ndawana thize. Kumelwe kube nendlela ecashile kakhulu yokusabalala kwalesi sifo.
'Iconsi' kanye 'ne-aerosol' - umehluko uyini?
Yilapho sithola khona igama elisha - 'i-aerosol'. Lokhu kubaluleke kakhulu ukukuqonda. Cabanga ngebhodlela lokufafaza. Uma ulifafaza, amaconsi amakhulu amanzi awela phansi, futhi kukhona nezinhlayiya zamanzi ezincane, ezingabonakali ezintanta emoyeni, njengenkungu, akunjalo? Kunjalo-ke.
'Amaconsi' afana nalawo maconsi amakhulu. 'Ama-Aerosol' afana nalawo maconsi amancane antanta emoyeni.
Ake sibheke umehluko phakathi kwalezi ezimbili ngale ndlela.
| Isici | Amaconsi amakhulu (Amaconsi) | Izinhlayiya ezincane kakhulu (ama-Aerosols) |
|---|---|---|
| Usayizi | Inkulu kakhulu (nakuba ingabonakali emehlweni) | Kuncane kakhulu (njengomusi) |
| Umphumela kumandla adonsela phansi | Iwela phansi ngokushesha (ngemizuzwana/imizuzu embalwa) ngenxa yesisindo sayo. | Ngenxa yokuthi ilula kakhulu, ingantanta emoyeni imizuzu, mhlawumbe amahora. |
| Ibanga lokuhamba | Ibanga elifushane (cishe amamitha angu-1-2). | Kungasakazeka ngisho nakulo lonke igumbi. |
| Indlela esakazeka ngayo | Ngokungena ngqo emzimbeni lapho othile ekhwehlela noma ethimula eduze. | Uma umuntu onegciwane ephefumula, ekhuluma, noma ehlabelela, lingena emoyeni bese liyaphefumula. |
Lapho amalungu alelo kwaya ehlabelela, lezi zinhlayiya ezincane (ama-aerosol) zakhishwa emoyeni wazo.Lonke igumbi kumelwe ukuba laligcwele umoya. Ngisho noma babeqhelelene kakhulu, bonke babephefumula umoya ofanayo, ngakho cishe wonke umuntu wagula. Lokhu kubizwa ngokuthi ukudluliselwa komoya .
Indlela ulwazi olusha olushintshe ngayo izimpilo zethu
Ngokuthola lokhu, izindlela esasizisebenzisa ukulawula ubhubhane zashintsha ngokuphelele.
Kusukela ekusuleni izindawo kuya ekucabangeni ngomoya
Ekuqaleni, sasicabanga ukuthi ukusula phansi, amatafula, kanye nezibambo zeminyango kwakuyinto ebaluleke kakhulu. Kodwa ngemva kokuqaphela ukuthi kuphuma emoyeni, safunda ukuthi kukhona okubaluleke nakakhulu. Futhi lokho kungumoya omuhle.
Kalula nje, ukugcina iminyango namafasitela evuliwe nokusebenzisa ifeni ukuhambisa umoya kunciphisa ukugcwala kwezinhlayiya zegciwane endaweni eyodwa.
Inani langempela lemaski
Ekuqaleni, izifihla-buso zazigqokwa ukuze kuvinjwe amaconsi amakhulu esasiwakhwehlela. Kodwa kamuva kwaqashelwa ukuthi isifihla-buso esihle njenge-N95 singahlunga ngisho nalezi zinhlayiya ezincane zamagciwane (ama-aerosols) ezintanta emoyeni. Ngakho-ke, ukubaluleka kwesifihla-buso kwanda kakhulu.
Lolu lwazi luzosisiza kakhulu ukuzivikela hhayi nje kuphela ku-Covid, kodwa nakunoma yiluphi ubhubhane lwezifo zokuphefumula esikhathini esizayo.
Umlayezo Wokuya Nawe Ekhaya
- Izifo zokuphefumula ezifana ne-COVID-19 zingasakazeka ngamaconsi amakhulu akhishwa lapho umuntu ekhwehlela, kanye nangezinhlayiya ezincane kakhulu (ama-aerosols) ezintanta emoyeni lapho ekhuluma noma ephefumula.
- Ingozi yokusabalalisa igciwane iphakeme ezindaweni ezivaliwe (amakamelo, amabhasi). Ngakho-ke, kubaluleke kakhulu ukugcina umoya ungena kahle , okusho ukugcina amafasitela evulekile.
- Ukugqoka imaski kusiza ekuvikeleni kokubili amaconsi amakhulu kanye nezinhlayiya ezincane ezintanta emoyeni.
- Isayensi ayimi ndawonye. Ulwazi lwethu nokuqonda kwethu kuyashintsha njengoba ubufakazi obusha butholakala. Ubhubhane luyisibonelo esihle salokho.
