Njengoba kuqala uMashi, abaningi babekholelwa ukuthi inkathi yomkhuhlane isizophuma. Kodwa imininingwane ekhishwe yiCenters for Disease Control (CDC) ngasekupheleni kwesonto eledlule iveze ukuthi izifundazwe ezingama-32 zibike amazinga aphezulu omkhuhlane, kanti angama-21 athi amazinga awo abephakeme kakhulu kunakuqala.

Ngokusekelwe enkathini yomkhuhlane obulalayo ebesinayo ngo-2017–2018 (isikhumbuzi: abantu abangaphezu kuka-80,000 bafa) sonke siyazi ukuthi umkhuhlane ungabikezelwa futhi ubulale. Kodwa okuthakazelisayo nge-spike yalo nyaka ezifweni ezibikiwe ukuthi igciwane le-H3N2, uhlobo olunzima kakhulu lomkhuhlane, lubangela iningi lezibhedlela. (Ingabe bewazi ukuthi amaphesenti angama-41 abantu baseMelika awazange ahlele ukuthola umkhuhlane, naphezu kwenkathi yomkhuhlane obulalayo ngonyaka odlule?)

I-H3N2 strain yiyona eyimbangela yamaphesenti angama-62 ezimo zomkhuhlane ezibikiwe ngesonto eledlule likaFebhuwari, kubika i-CDC. Ngesonto eledlule, ngaphezu kwamaphesenti angu-54 amacala omkhuhlane abikiwe abangelwa yi-H3N2.

Leyo yinkinga, ngoba umuthi wokugomela umkhuhlane kulo nyaka usebenza kangcono kakhulu uma uqeda uhlobo lwegciwane le-H1N1, olwalubaluleke kakhulu ekuqaleni kwenkathi yomkhuhlane ejwayelekile ngo-Okthoba. Ngakho-ke, uma uthole umkhuhlane, unethuba elingamaphesenti angama-62 lokukuvikela kuhlobo lwe-H1N1, uma kuqhathaniswa namaphesenti angama-44 kuphela uma kuqhathaniswa naleli gciwane le-H3N2 eliqhamukayo, ngokwe-CDC. (Thola Ukubhekana Ne-FluMist, Isifutho Sokugomela Umkhuhlane Amakhala)

Futhi, igciwane le-H3N2 libi kakhulu ngoba, ngaphezu kokubangela izimpawu zomkhuhlane ezivamile (imfiva, ukugodola, nobuhlungu bomzimba) lingaholela ezinkingeni ezinzima eziningana, okuhlanganisa imfiva ephezulu kakhulu efika ku-103° noma 104°F, kubika i-CDC. .

Akukhona lokho kuphela, kodwa nakuba amaqembu athile abantu ehlala esengozini enkulu yokuthola umkhuhlane, njengabantu abaneminyaka engu-65 nangaphezulu, izingane ezincane kanye nabesifazane abakhulelwe, i-H3N2 ngezinye izikhathi ingabangela izinkinga zempilo ezimbi ngisho nakubantu abanempilo enhle. Lokhu kungahlanganisa izinkinga ezifana nenyumoniya, engadinga ukulaliswa esibhedlela-futhi ngezinye izikhathi kubangele ukufa. (Okuhlobene: Ingabe Umuntu Onempilo Angabulawa Umkhuhlane?)

Leli gciwane lomkhuhlane nalo lihlala liguquguquka, okwenza ukuthi i-H3N2 itheleleke kakhulu, ibangele ukuthi lisabalale kalula lisuka kumuntu liye komunye. (Okuhlobene: Sinini Isikhathi Esingcono Sokuthola Isibhamu Somkhuhlane?)

Izindaba ezimnandi ukuthi, ngenkathi umsebenzi womkhuhlane kucatshangwa ukuthi uzohlala uphakanyisiwe kuyo yonke inyanga ezayo, i-CDC ikholelwa ukuthi kunethuba elingamaphesenti angama-90 lokuthi isizini isivele yafinyelela ezingeni likazwelonke. Ngakho-ke, sisekwehleni-whew.

Usengathola nokugonywa! Yebo, ukuthola umkhuhlane kungabonakala njengobuhlungu (noma okungenani, okwamanje omunye umsebenzi). Kepha uma kubhekwa iqiniso lokuthi sekuvele kukhona phakathi kuka-18,900 kanye ne-31,200 yokufa okuhlobene nomkhuhlane kanye nokulaliswa esibhedlela okungama-347,000 kule sizini, umkhuhlane kufanele uthathwe ngokungathi sína. O, futhi uma usutholile lokho kudutshulwa (ngoba siyazi ukuthi uphokophele lapho ASAP, akunjalo??) hlola lezi ezinye izindlela ezine ongazivikela ngazo kumkhuhlane kulo nyaka.
