Ucwaningo olusha oluholwa yi-Barcelona Institute for Global Health (ISGlobal), isikhungo esisekelwa yi-“la Caixa” Foundation, luhlinzeka ngobufakazi obuqinile bokuthi i-COVID-19 iwukutheleleka kwesizini okuxhumene namazinga okushisa aphansi kanye nomswakama, kufana nomkhuhlane wesizini.Imiphumela, eshicilelwe ku-Nature Computational Science, iphinde isekele umnikelo omkhulu wokudluliselwa emoyeni kwe-SARS-CoV-2 kanye nesidingo sokushintshela ezindleleni ezikhuthaza “ukuhlanzeka komoya.”
Ithimba libe selihlaziya ukuthi lokhu kuhlobana phakathi kwesimo sezulu nesifo kwavela kanjani ngokuhamba kwesikhathi, nokuthi kwakungaguquguquki yini ezilinganisweni ezihlukene zendawo.Kulokhu, basebenzise indlela yezibalo eyakhiwe ngokuqondile ukuze bakhombe amaphethini afanayo okuhlukahluka (okungukuthi ithuluzi lokuqaphela iphethini) kumawindi esikhathi ahlukene.Futhi, bathola ukuhlangana okuqinile okungalungile kwamafasitela wesikhashana phakathi kwezifo (inani lamacala) nesimo sezulu (izinga lokushisa nomswakama), namaphethini angaguquki ngesikhathi samagagasi okuqala, esibili, nawesithathu obhubhane ezilinganisweni ezahlukene zendawo: emhlabeni jikelele, amazwe. , kwehle kuya ezifundeni ngazinye ngaphakathi kwamazwe athinteke kakhulu (i-Lombardy, i-Thüringen, ne-Catalonia) ngisho nasezingeni ledolobha (Barcelona).
Amagagasi obhadane lokuqala ancipha njengoba izinga lokushisa nomswakama kuphakama, futhi igagasi lesibili lenyuka njengoba amazinga okushisa nomswakama kwehla.Nokho, leli phethini laphulwa ngesikhathi sasehlobo kuwo wonke amazwekazi."Lokhu kungachazwa yizici eziningana, okuhlanganisa ukubuthana kwabantu abasha, ezokuvakasha, ne-air conditioning, phakathi kokunye," kuchaza u-Alejandro Fontal, umcwaningi kwa-ISGlobal nombhali wokuqala wocwaningo.
Lapho kulungiswa imodeli ukuze kuhlaziywe ukuhlobana kwesikhashana kuzo zonke izikali emazweni aseNingizimu Nenkabazwe, lapho igciwane lafika khona kamuva, ukuhlobana okungalungile okufanayo kwabonwa.Imiphumela yesimo sezulu ibonakala kakhulu emazingeni okushisa aphakathi kuka-12ofuthi 18oC kanye namazinga omswakama aphakathi kuka-4 no-12 g/m3, nakuba ababhali bexwayisa ngokuthi lezi zigaba zisabonisa, uma kubhekwa amarekhodi amafushane atholakalayo.
Ekugcineni, lisebenzisa imodeli ye-epidemiological, ithimba locwaningo labonisa ukuthi ukufaka izinga lokushisa esilinganisweni sokudlulisela kusebenza kangcono ekubikezeleni ukukhuphuka nokuwa kwamagagasi ahlukene, ikakhulukazi awokuqala nelesithathu eYurophu.Sekukonke, lokho esikutholile kusekela umbono we-COVID-19 njengesifo sangempela sesizini sezinga lokushisa eliphansi, esifana nomkhuhlane kanye nama-coronavirus ahamba kahle kakhulu," kusho uRodó.
Lesi sikhathi sonyaka singaba negalelo elibalulekile ekudluliselweni kwe-SARS-CoV-2, njengoba izimo zomswakama ophansi kuboniswe ukuthi zehlisa usayizi wama-aerosols, futhi ngaleyo ndlela zandise ukudluliswa komoya kwamagciwane esizini afana nomkhuhlane."Lesi sixhumanisi siqinisekisa ukugcizelelwa 'kwenhlanzeko yomoya' ngokufakwa komoya okuthuthukisiwe kwasendlini njengoba ama-aerosol ekwazi ukuqhubeka nokumiswa isikhathi eside," kusho u-Rodó, futhi igqamisa isidingo sokufaka amapharamitha wesimo sezulu ekuhlolweni nasekuhleleni izindlela zokulawula.
Ngemva kweminyaka engu-20 yentuthuko, i-Holtop yenze umgomo webhizinisi “wokwenza ukwelashwa komoya kunempilo, ntofontofo nokonga amandla”, futhi yakha isakhiwo sezimboni esimeme sesikhathi eside esigxile emoyeni omusha, isimo sezulu kanye nezinkambu zokuvikela imvelo.Ngokuzayo, sizoqhubeka nokunamathela emisha kanye nekhwalithi, futhi ngokuhlanganyela siqhubekisele phambili ukuthuthukiswa kwemboni.
Ireferensi: "Amasignesha esimo sezulu kubhubhane oluhlukene lwe-COVID-19 amagagasi kuzo zombili izifunda" ngu-Alejandro Fontal, Menno J. Bouma, Adrià San-José, Leonardo López, Mercedes Pascual & Xavier Rodó, 21 October 2021, Nature Computational Science.
