Ayinamsebenzi nokuba imithombo yakho yeendaba yimithombo yeendaba zentlalo, iinethiwekhi zikamabonwakude, okanye ushicilelo, ikhonkco phakathi kohambo nokhenketho kunye nobhubhane lucacile. Ukuba umhlaba ubungengowamhlaba jikelele, into eqale e-China ngeyahlala e-China; Nangona kunjalo, intsholongwane isasazeka kuba abantu bahamba bejikeleza umhlaba-ngeenqwelomoya kunye neenqanawa zokuhamba ngenqanawa ngokudibanisa ukhetho lokuhamba komhlaba.
Ukuhamba kukhawulezisa ukuvela nokusasazeka kwezifo. Oku kusasazwa kuye kwenzeka kwimbali erekhodiweyo kwaye kuya kuqhubeka ukubumba imeko kaxakeka, ukuphindaphindeka, kunye nokusasazwa kosulelo kwiindawo zokuhlala nakubantu. Yintoni eyenza Covid-19 ezahlukileyo kwizifo zangaphambili kwisantya kunye nokufikelela kwesifo kunye nobungakanani bokusasazeka ngaphaya komhambi ukuya kubemi abatyelelweyo kunye ne-ecosystem yendawo ekubanjelwa kuyo umamkeli? Ukusasazeka kwezifo kuyisetyhula - nabahambi besabelana ngokugula kwiindlela zabo kwaye behlangabezana nemingcipheko emibi yempilo enokubakho kwiindawo apho indawo yokuhlala ingafikeleli khona kwimigangatho yezempilo yehlabathi kunye / okanye ukuziqhelanisa neenkqubo zokucoceka nezococeko.
Ubulapho
I-COVID-19 ayisiyo eyokuqala, kwaye ayisayi kuba yeyokugqibela, isifo sisasazeka kwihlabathi liphela ngokuhamba. Kwinkulungwane yama-20, sele sibonile ubhubhane obuninzi kubandakanya:
1. Umkhuhlane waseSpain (umkhuhlane) ngo-1918-1919
2. Umkhuhlane waseAsia (H2N2) - 1957
3. Umkhuhlane waseHong Kong - ngo-1968
Kwinkulungwane yama-21 kubekho izifo ezine:

3. IMERS - 2012
4. I-EBOLA - 2013-2014
Uphando lubonisa ukuba ukwanda kokuqhambuka kobhubhane ukusukela ngo-2000 kunxulunyaniswa nokukhula kwezokhenketho nakhenketho lwamashishini lwehlabathi. Ukuhamba kubalulekile kwi-epidemiology kunye nokusasazeka kwezifo; Ukuhamba zombini kunegalelo ekusasazeni isifo kwaye iziphumo zayo zoqoqosho zichaphazeleka kakhulu. Inyani emsulwa yeyokuba asinazixhobo zenkulungwane yama-21 zokulwa i-COVID-19. Iindlela ezikhoyo ngoku ezizama ukuvalela ubhubhane zazisetyenziselwa ukulawula ubhubhane kwiinkulungwane zokuqala kwaye zihlala ziphazamisa uqoqosho. Ngaphandle konyango kunye nokucotha ukufumaneka kwezitofu zokugonya ngenxa yokunqongophala kobunkokheli behlabathi kunye nenkxaso mali exhaswa noloyiko lokuba izitofu zizitatimenti zopolitiko endaweni yezisombululo zonyango, ilizwe liyakube lisebenza ngendalo efakwe yintsholongwane kwiminyaka ezayo.
