Pamwamba pa "zobiriwira" ndi omwe nthawi zonse amadzuka pankhani ya kutentha kwanyengo, chikondi chopusa. Ndipo zikuwoneka bwino pachabe. Asayansi ochokera ku United States, Germany ndi UK adamaliza kuti kusintha kwanyengo, ku China ndi zigawo zoyandikana nazo zitha kusewera mu covid-19. Ofufuzawo adafotokoza zomwe adazilemba m'sayansi za chilengedwe chonse.
Monga momwe amadziwika, chiwopsezo chakuti coronavirus inayake (cov) idzapeza katundu wa pathogenic, zimatengera mtundu mitundu yosiyanasiyana ya mbewa yokhazikika m'derali. Kenako, zachilengedwe zimatengera nyengo, zomwe zimayambitsa nyama kuti ziziyenda kumadera ena kupita ku ena. Ma mita amayamba kulumikizana ndi mitundu ina ya manyowa, omwe amatsegula njira zatsopano zoperekera ma virus kuti mugwire ma virus kuti apange nyoka.
Ofufuzawo adazindikira madera osiyanasiyana amitundu yosiyanasiyana kuyambira pachiyambi cha zaka za zana la 20 ndipo tsopano anawafanizira ndi zitsanzo za kugawidwa kwa maluwa padziko lonse lapansi, mogwirizana ndi nyengo inayake. Makhadi obisa zamasamba anali kutengera kutentha kwa mwezi uliwonse, mpweya, mitambo ndi kutentha pang'ono kuyambira 1901 mpaka 2019. Kulondola kwa njirayi kunatsimikiziridwa kale ndi malo othandiza.
Kenako makhadiwo adaphatikizidwa ndi zigawo zina ziwiri zodziwika: kudalira mbewa zosasunthika kuchokera ku mbewu zina ndi mtundu wina kapena mtundu wina wa mbewa zowoneka bwino (malo awa ndi opambana kuposa nyama yomwe yanyama). Zotsatira zake, ofufuzawo adalandira chidachi, chifukwa cha khungu lililonse lomwe limadziwika kuti maropiys amadziwika.
Ndikofunika kudziwa kuti njirayi siganizira zachitika zomwe zimachitika pazamera chifukwa cha zochita za anthu. Nthawi yomweyo, chigawo chakumwera kwa Yunnan ndi madera oyandikana nawo ku Myanmar ndi Laos Force adasandulika ndi kusintha kwa nyengo yomwe amasintha nkhalango zowonongeka. Zotsatira zake, kuchuluka kwa Coronavirses omwe amanyamulidwa ndi Mancrew, pafupifupi mitundu 50-150, yachulukanso pano (imodzi yankhondo), yomwe siyionedwa ina padziko lonse lapansi.
Monga olembawo amanenera kuti achepetse chiopsezo chofalitsidwa mtsogolo, ndikofunikira kuchitapo kanthu kuteteza malo okhalamo, amadziwitsa malamulo okhwima ndi miyambo yachitetezo.
