Ngelixa ilizwe lisatsala nzima intsholongwane ye-Corona engaziwayo, Esoyikela igagasi lesibini elizayo lobhubhani othe wasuba ubomi babantu abangaphezu kwesiqingatha sesigidi, wothuswa zezinye iindaba ezivelayo. I-China ibika ukuvela kwesinye isifo.

Umkhuhlane wehagu omandundu

Emva kokuba izazinzulu zaseTshayina zibhengeze ukuvela kwentsholongwane entsha ebizwa ngokuba yi-G4 EA H1N1, ichaza esi sifo njengohlobo olutsha lomkhuhlane olusuka ezihagwini lusiya ebantwini, kwaye lugxininisa ukuba abantu abanakukwazi ukulwa nalo okwangoku, uMbutho wezeMpilo weHlabathi nawo wakhalisa intsimbi. , yaza yabhengeza ukuba iza “kufunda ngenyameko” iingxelo zolu hlolisiso.

Kwiinkcukacha, isithethi sombutho sithe ukuvela kwentsholongwane efunyenwe kwiihagu kwiindawo zokuxhela e-China kubonise ukuba ilizwe kufuneka lihlale lithe qwa kwizifo ezitsha ngelixa liqhubeka nokujongana nokusasazeka kobhubhani we-Covid-19, ngokutsho. Iphephandaba laseBritane i-Independent, ngoLwesibini.

Ngomzuzwana uyazikhusela kwintsholongwane yeCorona, ngokutsho kukagqirha ophumelele iNobel

Ngeli xesha, uphononongo olupapashwe kwi-American Journal of the National Academy of Sciences, ngoMvulo, lukwakhanyisela uhlobo lomkhuhlane wehagu wosapho lwemfuza ye-G4, enazo zonke iimpawu ezisisiseko zentsholongwane enokwenzeka yobhubhane, ngokutsho kwabo bachaphazelekayo.

Ngelixa abaphandi bathi akukho sisongelo sisondele, izazi zebhayoloji zaseTshayina ezenze uphando zilumkise ukuba "ukubeka iliso ngokukhawuleza kufuneka kusetyenziswe ebantwini, ngakumbi abo basebenza kwishishini lengulube."

Kwelinye icala, uChristian Lindmeier, igosa elivela kuMbutho wezeMpilo weHlabathi, uthe kwinkomfa yabezindaba eGeneva ngoLwesibini, "Siza kufunda eli phepha ngononophelo ukuze siqonde into entsha," wongeza ngelithi "kubalulekile ukusebenzisana kwiziphumo kwaye ukuqhubeka nokubeka esweni amanani ezilwanyana."

Ucacisile ukuba intsholongwane "iqaqambisa ukuba umhlaba awunakulibala ukuba ulumke umkhuhlane, kwaye kufuneka uphaphe kwaye uqhubeke nokubeka iliso naxa ujongene nobhubhane weCorona," njengoko watshoyo.

Enye kwiintlobo ezi-3!

Kuyaphawuleka ukuba olu phononongo lucaphule unjingalwazi waseTshayina, uQin Chu Shang, esithi: “Ngoku sixakeke yintsholongwane ye-corona esakhulayo, kwaye sinelungelo lokwenjenjalo. Kodwa akufuneki siphulukane nombono wentsholongwane entsha enokuba yingozi, utshilo, ebhekisa kwiintsholongwane zehagu zeG4 "eziphethe zonke izinto ezibalulekileyo zentsholongwane yobhubhane." Inokosulela abasebenzi kwiindawo zokuxhela zaseTshayina, okanye abanye abasebenzi abasebenza. neehagu.

Intsholongwane entsha ngumxube omnye weentlobo ezi-3: enye ifana neyokufumaneka kwiintaka zaseYurophu naseAsia, oko kukuthi i-H1N1, i-H2009N1, i-strain yayo yabangela ubhubhane ngo-1, kwaye i-H4N4 yesibini yayiseNyakatho Melika, kwaye i-strain yayo iqulethe izakhi zofuzo ezivela kwi-avian. , iintsholongwane zomkhuhlane womntu kunye neehagu. ngokuchasene noxinzelelo olutsha, kodwa kukho ithuba lokuyilungisa kwaye isebenze, ngelixa ividiyo eboniswayo iphosa iinkcukacha ezingaphezulu.

Kwaye kukho omnye umthathi-nxaxheba kunye neqela elilungiselela isifundo, u-Edward Holmses waseOstreliya, isazi ngebhayoloji kwiYunivesithi yaseSydney, ogxile ekufundisiseni iintsholongwane ezibangela izifo, yaye kuyo uthi: “Kubonakala ngathi le ntsholongwane intsha isendleleni yokuya. zibonakala ebantwini, kwaye le meko ifuna ukujongwa ngononophelo.”

Omnye usosayensi, iLanga laseTshayina uHonglei, ogxile ekugunyazisweni kwezenzululwazi, uhambe naye, egxininisa ukubaluleka “kokuqinisa uphononongo” lweehagu zaseTshayina ukuze zibone intsholongwane “kuba ukufakwa kofuzo lwe-G4 kubhubhani we-H1N1 kunokuphucula ukuziqhelanisa neentsholongwane. , nto leyo ekhokelela kusulelo olusuka komnye umntu luye komnye,” njengoko Etshilo.

Ngaphezu kwe-500 yezigidi zeehagu

Elinye iqela lezenzululwazi, elikhokelwa ngusosayensi uLiu Jinhua, umlweli we "Chinese Agricultural University" uhlalutye "ii-biopsies" ezingama-30 eziye zasuswa kwiimpumlo zeehagu kwiindawo zokuxhela kumaphondo ali-10 aseTshayina, ukongeza kwezinye iihagu eziyi-1000 ezineempawu zokuphefumla, kwaye kwacaca kwezi sampuli ziqokelelweyo.Phakathi kwe-2011 kunye ne-2018, yayine-virus ye-swine influenza ye-179, ininzi yazo yayiyi-G4 strain okanye enye ye-G strain ye-"Eurasian" yeentaka, oko kukuthi, iYurophu ne-Asia. , kwaye kwavela ukuba i-G4 ibonise ukunyuka okubukhali ukusuka kwi-2016 kwaye iyona genotype ehamba phambili ekujikelezeni kweehagu ezifunyenwe kumaphondo angama-10 aseTshayina ubuncinane.

Nangona kunjalo, uMartha Nelson, isazi ngebhayoloji kwiFogarty Global Centre eUnited States, uqinisekisile ukuba amathuba okuba intsholongwane entsha isasazeke njengobhubhane “uphantsi, kodwa kufuneka siphaphe, kuba umkhuhlane unokusothusa,” njengoko wacebisayo. , kuthathelwa ingqalelo ukuba eTshayina Ngaphezu kwezigidi ezingama-500 zeehagu, kunye nentsholongwane esandul’ ukuzalwa inokudluliselwa ukusuka komnye umntu ukuya komnye, nayo efuna ukuqinisekiswa okungakumbi.

I-China yazisa ngokusemthethweni

Ukongeza, isithethi seSebe lezangaphandle laseTshayina uZhao Lijian uthe kwinkomfa yabezindaba ngoLwesibini ukuba urhulumente "ulandela ngokusondeleyo okwenzekayo kulo mba." “Siza kuthatha onke amanyathelo ayimfuneko ukuthintela ukusasazeka kwayo nayiphi na intsholongwane,” wongeze watsho.

Kuyaphawuleka ukuba umkhuhlane wehagu ushiye ngaphezulu kwe-700 yezigidi zosulelo kwihlabathi liphela ngo-2009, ukongeza malunga ne-17 yokubhubha okuqinisekisiweyo okuxelwe nguMbutho wezeMpilo weHlabathi, ngelixa kukho ulwazi lokuba ubhubhane ubulale ngaphezulu kwenani elikhankanyiweyo.
