Global Updates uye Yakakosha Inotevera Matanho muKurwisa HPAI
27 June 2023
High Pathogenicity Avian furuwenza (HPAI) inyaya yepamusoro-soro inobata mabhizinesi emazai uye misika yakakura pasirese. Kupa mukana wakakwana wekugovana ruzivo uye nekuvandudzwa kwepasirese, iyo IEC Bhizinesi Musangano muBarcelona yakavhurwa nenyanzvi dzeindasitiri dzichiongorora iyi inopisa musoro uye kuti tinokunda sei pamwe chete matambudziko anomutsa AI.
Avian Influenza - chii chiri kuitika pasi rose?
Kupa mamiriro akakosha kunhaurirano, zvikamu zvakatanga nekuvandudzwa kwedunhu pazvino AI mamiriro kubva kune vamiriri venyika 5. Shanyira chinongedzo chiri pazasi kuti uongorore idzi nhengo-chete zvigadziriso izvozvi.
Evolution yeAvian Influenza uye Kudzora Nzira
Kune chikamu chinotevera chechirongwa, Dr David Swayne, Veterinarian uye Global AI Nyanzvi, vakakurukura kushanduka kweAI uye nzira dzekutonga, kubva pakuona kwesayenzi.
Dr Swayne vakatsanangura kuti AI hutachiona hudiki hunokwanisa kuramba huchichinja uye kuchinja, kutora zvikamu zvakanakisa zvemajini pakati pemavhairasi akasiyana eAI kuti agadzirise nawo. Akawedzera kuti hutachiona hweAI hunogona kusiyana zvakanyanya mubhayoroji yavo: "Isu tinoisa AI mumapoka maviri akasiyana - yakaderera pathogenicity, kana chirwere chakapfava chinokonzera hutachiona, uye yakakwira pathogenicity, izvo zvinokonzeresa hosha dzinouraya."
Mamwe mavhairasi epathogenicity akaderera (H5s neH7s) anozochinja kuita hutachiwana hweavian influenza (HPAI). Hutachiona uhu hunogona kubata huku neshiri dzesango, zvichienderana nehutachiwana hwehutachiwana, Dr Swayne vakadaro.
Chii chakasiyana nezvehutachiona hwazvino?
Nekuomerwa kwazvino kweHPAI (H5N1) ine mhedzisiro inoparadza muindasitiri yepasi rose, Dr Swayne vakatsanangura misiyano yakakosha mumutsara wehutachiona uhwu zvichienzaniswa nemhando dzakapfuura.
Akatsanangura kuti chinoita kuti hutachiona uhu huve hwakasiyana kugona kwahwo kusangana pakati pemadhadha epanyika nehuku dzepasi: “Kudivi rekurima, 'Achilles chitsitsinho' chedu madhadha epamba. Ndivo vanonyanya kutapukirwa nehutachiona hweHPAI parudzi rwedu rwese. " Izvi zvinokonzerwa nemadhadha epamba kuve "mukuru wehutachiona", sezvo ane hutachiona uye zvakanyanya asymptomatic.
Zvinotora utachiona hwakadii kugadzira utachiona muhuku?
Mutauriri wenyanzvi akatsanangura kuti 1g yetsvina ine hutachiona hunosvika mamirioni gumi, uye 10 g yemate mumhepo yekufema ine hutachiona hunosvika mamirioni zana: pashangu.”
Kuratidza mukana wekutapukirwa kubva muhuwandu uhu, akawedzera kuti: “Mukubuda kudiki uko hutachiona hwaingopararira zvishoma, takaona kuti zvinotora zvidimbu zviri pakati pe1,000 ne50,000 kuti uwane hutachiona muhuku. Kana tikatarisa kubuda kukuru, zvinotora kubva padiki kusvika pagumi nematanhatu kusvika pazviuru zvehutachiona. ”
Tinorwisa sei utachiona uhu?
“Purazi roga-roga rinofanira kuva nehurongwa hwakakwana hwekuchengetedzwa kwezvipenyu hwakanyorwa pasi, uye hunodzidziswa kuvashandi vose vepapurazi,” vakadaro Dr Swayne. "Uye hurongwa uhu hunoda kuongororwa kuti uone kuti unowana zvese zvisina kusimba zvinongedzo uye kugadzirisa, kuitira kuti uchengetedze makwai paakanakisa uye nenjodzi yakaderera yekusuma."
Nyanzvi yakaona mutsauko wakakosha mu 'mutsara wekuparadzanisa' nehutachiona hwazvino, vachikurukura kuti kare biosecurity pagedhi repurazi yaizoichengeta sei kunze, nepo iko zvino, nekuti yakaparadzirwa neshiri dzesango, gedhi harina kukwana zvakakwana. Pane kudaro, iyo biosecurity inofanirwa kukwira kumusuwo wedanga, sezvo shiri dzesango dzinogona kupinda nekusvibisa nharaunda chero papurazi.
Pasinei nekuziva kukosha mumatanho akadaro, Dr Swayne akabvumawo kuti "biosecurity inoderedza ngozi, asi haibvise", yakaratidzwa nekuenderera mberi kwechirwere kunyange nezvirongwa zviri nani.
Pamusoro peizvi, akacherechedza matambudziko akawanda ane chekuita ne'kupedza' chirwere ichi, kusanganisira kuwedzera kwemari yezvirongwa zvakadaro; zvinetso zvehutano hwemhuka; uye maitiro ekuita kweiyi nzira, zvichireva kuti inowanzopararira kune inotevera boka usati wagona kuita chiito.
Vachitaura nezvekubuda kwehutachiona huchangoburwa, Dr Swayne vakati: "Dzimwe nyika hadzina kukwanisa kuenderera mberi nechirwere ichi uye kubuda kwacho hakuna kushanda pakubvisa. Utachiona hwacho hwakatanga kupararira uye, nekudaro, zhinji dzenyika idzodzo dzakashandisa jekiseni. ”
Chii chinogona kuita jekiseni?
Nejekiseni riri kuongororwa pasi rose sechimwe chishandiso chekurwisa AI, Dr Swayne vakapa ruzivo nezvechinangwa chesainzi uye mhedzisiro yekudzivirira. Akatsanangura kuti kubaya kwekudzivirira kunowedzera kupokana nehutachiona hweAI, kuitira kuti hutachiona husazodzokorora muboka rekudzivirira zvirwere. Vaenderera mberi vachiti dzimwe shiri dzinenge dzabaiwa majekiseni dzinogona kuzobatwa nechirwere ichi apo neapo, asi dzinobereka hutachiwana hushoma, kudzivirira zvirwere nerufu.
Akapfupikisa: “Zvinorehwa neizvi mumufananidzo mukuru ndezvokuti, kune kuderedzwa kwekusvibiswa kwezvakatipoteredza, kuderedzwa kwekutapurirana mukati menzvimbo iyoyo, uye kuderedza kupararira pakati pematura nemapurazi - izvo zvinotungamira kuchengetedza raramo yevarimi nekuchengetedzwa kwechikafu kwevatengi, uye zvinovandudza. hutano hwemhuka."
Nderipi Basa Ringaitwa neMajekiseni muAvian Influenza Control?
Tichitevera ruzivo rwesainzi rwaDr Swayne, Carel du Marchie Sarvaas anobva kuHealth for Animals akawedzera kuongorora basa remishonga yekudzivirira uye matanho anodiwa kuti awedzere kune yedu AI control toolkit.
Vakavhura nekupa ruzivo nezve mashandisirwo emazuva ano kwemishonga pasi rose: “Baccination yanga ichiitika mumisika yakawanda yakasiyana – kune majekiseni ekudzivirira kana usati waita denda, uye kune majekiseni echimbichimbi epanguva yaunenge wawana. kunyuka nekupararira." Akawedzera kuti, panguva ino, nzira dzakajairika dzekudzora dzinoramba dziri biosecurity uye kuongorora.
Carel akabva akurukura nezve nhanho dzinodiwa kuti dziitwe zvakakura pasi rose, kusanganisira: miyedzo yekudzivirira uye maitiro ekubvumidza, zano rekudzivirira, masisitimu ekutarisa, mari, uye zvibvumirano zvezvematongerwo enyika. "Mugwagwa wakaoma", akadaro "Uye zvese izvi zviri kuitika neimwe nzira munyika dzakasiyana."
Nyanzvi yakaongororawo maparamendi ekudzivirira anoda kuongororwa, semuenzaniso, danho rekubuda kwehutachiona, nguva yekudzivirira, kuona shiri dzine hutachiona uye dzisina kutapukirwa, uye nzira yekutonga: "Kune marudzi ese akasiyana siyana ayo. zvinofanira kufungwa nezvazvo.”
Kutarisa kune ramangwana
Carel akapedzisa nekupa tarisiro yeramangwana rejekiseni reAI: “Havasi vagadziri vejekiseni vanosarudza kuti panofanira kuva nejekiseni here kana kuti kwete, ndidzo hurumende. Uye hurumende dzinoita izvi dzichitaurirana nemasangano akasiyana. Chokutanga uye chinonyanya kukosha, chokwadi, indasitiri yehuku uye mazai. Asi ndinofunga sekushanduka kuri kuitika, vamwe vatambi vezvemagariro vari kuuya munzvimbo iyo hurumende dzine hurukuro navo. "
Ndokumbira utarise: ruzivo rwataurwa muchinyorwa chino rwakanga rwuri rwechokwadi panguva yemharidzo (15 Kubvumbi 2023).
