Pamene dziko likulimbanabe kachilombo ka corona m'buyomu sizinawonedwe mwa anthu, Powopa funde lachiwiri lomwe likubwera la mliri womwe udapha anthu opitilira theka la miliyoni, adadzidzimuka ndi nkhani zina zomwe zimachokera. China ikunena za kutuluka kwa matenda ena.

Chimfine chachikulu cha nkhumba

Asayansi aku China atalengeza za kutuluka kwa kachilombo katsopano kotchedwa G4 EA H1N1, kufotokoza za matendawa ngati mtundu watsopano wa chimfine chomwe chimafalikira kuchokera ku nkhumba kupita kwa anthu, ndikugogomezera kuti anthu alibe chitetezo cholimbana nacho, bungwe la World Health Organisation nalonso lidawomba belu. , ndipo analengeza kuti “iwerenga mosamala” malipoti a kafukufukuyu.

Mwatsatanetsatane, mneneri wa bungweli adati kuwonekera kwa kachilomboka komwe kapezeka mu nkhumba m'malo ophera nyama ku China kukuwonetsa kuti dziko liyenera kukhala tcheru ku matenda atsopano ngakhale likupitilizabe kuthana ndi kufalikira kwa mliri wa Covid-19, malinga ndi nyuzipepala yaku Britain The Independent, Lachiwiri.
