Nō nā tata nei,Te Wiki o te CDC o Hainai whakaputa i tētahi tuhinga rangahau nui e whakaahua ana i te rangahau mate urutā me te take o te pakarutanga o te mate puku whakapeka i puta mai i te rotavirus Rōpū C (RVC) i tētahi kura tuatahi i Luzhou, Porowini o Sichuan, i te Oketopa 2025. He mea nui, ko te kete hopu mate whai hua nui a Macro & Micro-Test (hopu-tirotiro) me te hangarau raupapatanga whakarei ira katoa he mea nui i roto i te rangahau. Mā te whakahohe i te tautuhi tika i te mate me te tautuhi ira whānui, i whakaratohia e te hangarau he taunakitanga pūtaiao nui mō te whakaū tere i te pakarutanga, te rapu tika i te pūtake, me te whakahaere pakarutanga whai hua.
Te Pakarutanga Ohorere: Te Pakarutanga RVC Tuatahi i Pūrongotia i te Tonga-mā-uru o Haina
I te 15 o Oketopa 2025, i puta he pakarutanga o te mate puku whakapeka i tētahi kura tuatahi i Luzhou. E 1,943 ngā ākonga me ngā kaimahi o te kura, ā, e 32 ngā kēhi i pūrongohia, tae atu ki te 6 i whakaūhia e te taiwhanga me te 26 i tātaritatia e te haumanu, ā, ko te reiti whakaeke katoa he 1.65%. I eke te pakarutanga ki te tihi i waenga i te 15 me te 16 o Oketopa, ā, ko te Akomanga 7, Akomanga 5 te mea i pāngia e te reiti whakaeke teitei rawa atu (23.08%). Ko te nuinga o ngā tūroro he tamariki kura (tau waenga: 10 tau), ā, ko te nuinga o ngā tūroro he ruaki (65.62%), he korere (46.87%), me te mamae o te puku (37.50%). Ko ngā tohumate he 1–3 rā te roa, ā, i ora katoa ngā tūroro me te kore he raruraru kino.
I kitea i roto i te rangahau mate urutā te kēhi matua he tamaiti 11-tau te pakeke i te Akomanga 7, Akomanga 5. I pāngia tōna teina e ngā tohumate rite i mua atu i a ia, e kī ana ko te pūtake tuatahi o te horapa ko te kāinga. Nā te kore e tika te whakahaere i te ruaki i roto i te kāmpus—tae atu ki te horoi tika me te whakakore i te mate me te kore e patu huakita i te wā tika, te wehe rānei i te rohe—me te kore hoki e pai te akuaku ringa i waenga i ngā ākonga, tera pea i āwhina i te horapa atu. Ko te nuinga o ngā akomanga i pāngia i waenganui i te papa tuarua me te papa tuarima, ā, i tū tata ngā wharepaku tāne, e tohu ana ko te aerosol me te horapa pā pea i whai wāhi ki te horapa.
I tino uaua te rangahau nā te mea i puta he hua kino i roto i te tirotiro i ngā mate urutā o ia rā, tae atu ki ngā whakamātautau mō te norovirus me te rotavirus Rōpū A, e tohu ana he mate urutā onge te take.
Tātaritanga Taketake: Mā te Raupapatanga Ira Katoa o te Macro & Micro-Test e Tāutuhia te Kaihara
I te whakamātautau tuatahi mō te norovirus, kāore i kitea he pai. I muri mai, i whakamahia e te CDC o Luzhou tētahi whakamātautau PCR wā-tūturu mō ngā mate puku maha, ka taea te kite i ngā mate e 28 i te wā kotahi, tae atu ki ngā huaketo e 8, ngā huakita e 17, me ngā pirinoa e 3, hei tirotiro i ngā tauira haumanu e waru. I te 17 o Oketopa, e ono ngā tauira i whakamātauhia he pai mō te rotavirus Rōpū C, ā, i kitea angitu ai te mate pūtake.
Hei whai atu i te pūtake o te pakarutanga, i whakahaerehia e ngā kairangahau te raupapatanga metagenomic nanopore me te raupapatanga whakarei ake i te ira katoa a Macro & Micro-Test ki runga i ngā tauira pai e rima. I angitu tēnei huarahi ki te whakaputa i ngā raupapatanga ira RVC katoa e rima (SC01–SC05). Nā te rautaki whakauru o te tirotiro PCR maha-whakatere tere i whai muri mai i te raupapatanga ira katoa taumira teitei i whakarato i te tautoko hangarau pakari mō te mate urutā ngota tika me te whai pūtake.
Ngā Tirohanga Pūtaiao: Te Tāututanga Tuatahi o te Ira M2 i te Tonga-mā-uru o Haina
I runga i ngā raraunga kounga teitei mō te ira katoa i hangaia mā te whakamahi i te hangarau a Macro & Micro-Test, i pūrongo te tīma rangahau i ētahi kitenga pūtaiao nui:
Te whakaū i te pakarutanga monoclonal:He rite tonu te momoira ira katoa o ngā momo huaketo e rima (G4-P[2]-I2-R2-C2-M2-A2-N2-T2-E2-H2), me ngā rerekētanga ira kotahi (SNP) 0–1 anake, e whakaatu ana i te pūtake o te pakarutanga mai i tētahi mekameka tuku kotahi.
Te kitenga o te momoira M2:I whakaatuhia e te tātaritanga phylogenetic ko ngā momo RVC o Luzhou nō te iraira M2, kaua ki te iraira M3 i whakaarohia i mua ko te nuinga i roto i ngā momo RVC Hainamana. E wero ana tēnei kitenga i te māramatanga tuku iho o te tohatoha iraira RVC i Haina, ā, e whakaū ana i te putanga mai o te iraira M2 i te tonga-mā-uru o Haina.
Ngā taunakitanga o ngā hononga tuku kōrero ā-ao:I whakaatuhia e te whakataurite ira-katoa te ōritenga nui o ngā ira i waenga i ngā momo Luzhou me ngā momo RVC i pūrongohia i mua i Yunnan (2025), Novosibirsk, Rūhia (2017), me Itari (2012), e whakaatu ana i te noho o tētahi whatunga tuku ira o Ūropi.
Ngā Pānga mō te Ārai me te Whakahaere: He Mea Hira te Kitenga Wā Moata me te Wawaotanga Tere
Whai muri i te tautuhi i ngā mate pāwera, ka whakatinanahia tonutia e te CDC o Luzhou ngā mahi whakahaere whānui, tae atu ki te wehe kēhi, te patu huakita taiao, te whakahaere ruaki paerewa, me te whakamutu akomanga wā poto. I angitu te pehi i te pakarutanga i roto i te wā whakatipu kotahi, me te kore he kēhi anō i pūrongohia i muri i te 21 o Oketopa.
He akoranga nui anō hoki tēnei mō te hauora tūmatanui: mō ngā pakarutanga o te mate puku e kitea ana he kino te hua o te whakamātautau mō te rotavirus Rōpū A me te norovirus, me whakauru te rotavirus Rōpū C me ētahi atu rotavirus ehara i te Rōpū A ki ngā whakamātautau tātaritanga o ia rā.
Ko tēnei rangahau te tuatahi o ngā pūrongo mō te pakarutanga o te rotavirus Rōpū C i te tonga-mā-uru o Haina, me te tuatahi hoki o te tautuhi i te momoira M2 i te rohe, e whakawhānui ana i te māramatanga o nāianei mō te mate urutā RVC i te Rawhiti o Āhia. I roto i tēnei rangahau, ko te otinga whakauru a Macro & Micro-Test e whakakotahi ana i te tirotiro PCR maha-pūnaha me te raupapatanga whakarei ira katoa i whakaatu i te uara mahi nui mā te whakahohe i te tautuhi tere i ngā mate me te rapu pūtake ngota ngota teitei-taumira, e whakarato ana i tētahi anga hangarau ka taea te tāruarua mō te rangahau tika me te whakahaere i ngā pakarutanga mate pāwera a meake nei.
