Kunyangwe mushure mekunge tapfuura - uye tichiri kupfuura - denda re coronavirus, Covid-19 uye kubuda kwe monkeypox, mamiriro ehutano hwepasi rose anoramba ari panjodzi neimwezve pathological agent. Tiri kutaura nezveutachiona hutsva Langya henipavirus (LayV) yakabata vanhu vanosvika makumi matatu neshanu muChina pakati pa35 na2018, ichitaurwa mumotokari yesainzi.

Pakati pezviitiko zvinotsanangurwa mu The New England Journal of Medicine, 26 yavo yakaongororwa zvakadzama, uye zviratidzo zvinotevera zvakasimbiswa:
- 54% - kuneta;
- 50% - chikosoro
- 35% - musoro;
- 35% - kurutsa.
Pakanga panewo zvinyorwa zvekusagadzikana muchiropa mu35% yevarwere uye muitsvo mu8% yavo. Kunyangwe paine data rese rezviratidzo, hapana nyaya yekuzofa isati yataurwa. Kutapurirana hakunawo kuratidzwa sekuonana-munhu-kune-munhu, pamwe hutachiona hune mhuka yakabva. Zvidzidzo zvinoratidza kuti shrew - rudzi rwemakonzo madiki akafanana nembeva - inzvimbo yakasikwa yehutachiona, asi pasina humbowo kusvika parizvino.
Nyanzvi dzinoti, zvisinei nekuonekwa kweutachiona hutsva uhu, hahuna simba rekukonzeresa denda idzva. Izvi hazvirevi kuti hapagoni kuva nehanya, sezvo mamwe zvirwere zveHenipavirus zvakatokonzera zvirwere zvakakomba uye kuputika munzvimbo dzakadai se Oceania e Asia, kunyanya iyo Hendra henipavirus (HeV) uye zvakare Inipa hepatitis (NiV), inoonekwa yakafanana neLayV.
Izvo zvakacherechedzwa hazviratidze nzvimbo inopisa ("kutarisisa kwekutapurirana", mukududzira kwemahara) sezvazvaive zvakaita nekoronavirus - umo hutachiona hwakawanikwa uye nekukurumidza hwakatanga kupararira mudunhu rese nekukurumidza. Hutachiona hutsva zvakare hwaisaratidza kutapurirana kwemunhu-kune-munhu nekukurumidza. Asi sehutachiona hwepathogenic (hunokonzera chirwere), zvinodikanwa kuti utarise uye utarise nyaya nyowani.

Hazvisi nyore kubatanidza huwandu hwevanhu vanofa kubva kukoronavirus, denda razvino, nezvirwere zvinokonzerwa nehutachiona. Langya henipavirus, sezvo kune zvinhu zvakadai senguva uye nhamba munyika imwe neimwe zvisina kuenzana. Mavhairasi Nipah e Hendra vatove nenhanho yekuuraya iyo isina kungofanana asi yakatokwira, munzvimbo idzi, kupfuura iyo coronavirus pachayo.
Izvo zvakakosha kusimbisa izvo kunyangwe mukudhindwa kwakaitwa mu New England Journal of Medicine, zvakaratidzwa kuti Langya henipavirus varwere vane utachiona vanogara mumatunhu Henan e Shandong. Pakanga pasina chirevo chekuti vaive nekubatana nemumwe kana chero rudzi rwenhoroondo yekuvapo munzvimbo imwechete. Vatsvagiri vakaitawo nzira yekutevera vapfumbamwe vevarwere ava nehama dzavo kuitira kuti vaone kana paine chiratidzo chehutachiona hwemunhu-ku-munhu - asi mhedzisiro yacho yanga isina kunaka.

Uripo muchirongwa National Wild Animal Virus Surveillance Network (Predict), Jansen de Araujo Kuvapo kweHenipavirus muBrazil kwave kuchitsvakwa kwemakore. Muna 2017, virologist nevamwe vaaishanda navo vakatoburitsa chinyorwa chaive nehumbowo mumabhati anowanikwa muBrazil angangovewo matura eNipah, asi pakanga pasina humbowo hwesainzi. Kwete Nipah chete, muongorori anoti zvakare nyaya dzehutachiona hweHendra hadzisati dzaonekwa munyika zvakare.
Imwe nyanzvi munyaya iyi, chiremba wemhuka Michele Lunardi, PhD muhutachiona hwemhuka, yakabudiswawo nevamwe vaanoshanda navo chinyorwa chekuongorora zvidzidzo zveHenipavirus muna 2021, ichisimbisa kuuraya kweNiV neHeV. YeBBC News Brasil, chiremba anoti masayendisiti ane basa rekuzivisa Langya henipavirus muChina zvakaitika kuburikidza nekuongororwa kwemaitiro muzviitiko zvefivha, chiito chinotsanangurwa sechakakosha nenyanzvi kudzivirira izvi nezvimwe zvirwere kuti zvisapararire.
Varwere vane febrile vanooneka kunochengetwa muzvipatara zvakasarudzwa muChina uye, pavanotaura nezvekumbosangana nemhuka, masampuli anounganidzwa kuti aongorore metagenomic. Zvishandiso zvine simba zvekuziva utachiona. Iri rudzi rwekutarisisa kunoshanda neitsva (genetic) kutevedzana maturusi akakosha zvakanyanya, tichifunga izvi zvinotapukira zvinotapukira zvinogona zoonotic - kureva, izvo zvinotapuriranwa kubva kumhuka kuenda kuvanhu. Isu tinoziva kuti vane mukana wakakura wekuva vamiriri vatsva vedenda mune ramangwana.
