Nheyo dzekutanga dzeEpidemiology muMishonga yeZvipfuyo
Epidemiology kudzidza maitiro, zvikonzero, uye zvinhu zvinopesvedzera kuitika kwezvirwere mumapoka evanhu. Mukurapa kwezvipfuyo, epidemiology inoita basa rakakosha nekuti hutano hwemhuka hahungogumiri pakuita goho uye kugara zvakanaka kwemhuka asiwo hwakabatana zvakanyanya nehutano hwevanhu kuburikidza nepfungwa yeOne Health—kubatana kwevanhu, mhuka, uye nharaunda. Kunzwisisa epidemiology kunobatsira vanachiremba vezvipfuyo , varimi, nevanogadzira mitemo zvinobudirira kudzivirira, kuona, uye kudzora zvirwere, kunyanya mukurima zvipfuyo zvakanyanya uye mumhuka dzesango.
1. Hukuru hweEpidemiology yeZvipfuyo
Kuongororwa kwezvirwere zvemhuka kunotarisa pakuitika kwezvirwere mumapoka emhuka, kwete pamunhu mumwe chete. Nokudaro, nzira yaro inosanganisira kutarisa kuwanda kwezvirwere, kuona zvinhu zvinokonzera njodzi, kuongorora zvirongwa zvekudzivirira, uye kuronga nzira dzekudzora. Mienzaniso yekushandiswa kwekuongorora zvirwere zvemhuka inosanganisira kutarisa zvirwere zvemhuka (semuenzaniso, chimbwamupengo, leptospirosis, brucellosis), zvirwere zvinotapukira (semuenzaniso, furuwenza yeshiri, chirwere chetsoka nemuromo), uye zvirwere zvekugadzira zvinowanzoenderana nekutarisira (semuenzaniso, mastitis mumombe dzemukaka kana coccidiosis muhuku).
Pamusoro pezvirwere zvinotapukira, epidemiology inoshandiswawo kuongorora matambudziko ehutano asina kutapukira akadai sekuchetura kwezvikafu, kushushikana nekupisa, matambudziko ekudya, uye matambudziko ehutano hwemhuka uye kukanganisa kwazvinoita pakubudirira kwekugadzira.
2. Pfungwa yeKuyera Huwandu hwevanhu, Nyaya, uye Zvirwere
Nheyo huru yekuongorora zvirwere ndeyekuona chirwere sechiitiko chehuwandu hwevanhu. Vanachiremba vemhuka vanofanirwa kutsanangura zvakajeka "huwandu hwevanhu vari panjodzi," inova boka remhuka dziri panjodzi yekurwara nechirwere mukati menguva yakatarwa.
Kugadzira tsananguro yenyaya kwakakosha pakunyorwa nekuongororwa nguva dzose. Tsananguro yenyaya inogona kuva yekiriniki (ichibva pazviratidzo), yerabhoritari (ichibva pamigumisiro yebvunzo), kana musanganiswa wezvose zviri zviviri. Semuenzaniso, nyaya yekiriniki yemastitis inogona kutsanangurwa sekuchinja mumukaka pamwe chete nekuzvimba kwezamu, nepo subclinical mastitis ichida kuongororwa kwakadai sekuwanda kwemasero mumuviri kana bvunzo yeCMT.
Kuti uongorore huwandu hwechirwere, pane nzira mbiri huru dzekuongorora:
1. Kuitika kwechirwere: huwandu hwezviitiko zvitsva zvinoitika muvanhu vari panjodzi munguva yakatarwa. Kuitika kwechirwere kunobatsira pakuongorora njodzi uye kushanda kwezvirongwa zvekudzivirira chirwere.
2. Kuwanda kwevanhu: huwandu hwevanhu vanorwara panguva yakatarwa. Kuwanda kwevanhu kunobatsira kutsanangura mutoro wezvirwere muvanhu.
Munyaya yezvipfuyo, ruzivo rwehuwandu hwevanhu vanorwara uye huwandu hwevanhu vanorwara runogona kushandiswa kutarisa mafambiro ezvirwere, kuenzanisa mapurazi, uye kuona zvinodiwa kuti zvipindirwe.
3. Epidemiological Triad: Mumiriri, Mugamuchiri, uye Nzvimbo Yakatipoteredza
Nyanzvi yezvezvirwere zvechinyakare inoziva pfungwa ye "epidemiological triad," iyo inoumbwa nemushonga, mupi, uye nharaunda. Zvirwere zvinoitika kana zvikamu izvi zvitatu zvichisangana pasi pemamwe mamiriro ezvinhu.
– Mushonga chinhu chinokonzera zvirwere, senge bhakitiriya, hutachiona, tupukanana, fungus, kana chepfu. Hunhu hwemushonga, hwakadai sehutachiona, huwandu hwehutachiona, uye kugona kurarama munzvimbo yakapoteredza, zvinokanganisa maitiro ezvirwere.
– Chipfuwo chinowanzobatwa nezvirwere. Zvinhu zvinoumba chipfuwo zvinosanganisira zera, mamiriro ekudzivirira muviri, majini, kudya kunovaka muviri, kushushikana, uye mamiriro emuviri akadai sepamuviri.
– Nzvimbo iyi inosanganisira zvinhu zvekunze zvinokanganisa kupararira kwezvirwere uye kutapurirana kwezvirwere, zvakaita sekuchenesa makeji, kuwanda kwevanhu, hunyoro, tembiricha, kunaka kwechikafu nemvura, uye kuvapo kwezvipembenene zvinotakura utachiona.
Semuenzaniso, kubuda kwezvirwere zvekufema mumombe kunogona kukonzerwa nemavhairasi kana mabhakitiriya, zvichiwedzerwa nekunetseka kwekutakura mhuka, uye zvichitsigirwa nenzvimbo dzisina mhepo yakakwana mumatanga.
4. Kupararira kwezvirwere zvinotapukira uye mafambiro azvo
Muzvirwere zvinotapukira, kunzwisisa nzira yekutapurirana kwakakosha. Nzira yekutapurirana inosanganisira kwakabva chirwere, kuti chirwere chinobuda sei mumuviri, nzira yekutapurirana, nzira yekupinda nayo, uye munhu ari nyore kutapurirana. Nzira dzekutapurirana dzinogona kusanganisira:
- Kusangana zvakananga pakati pemhuka
- Kubata zvisina kunanga kuburikidza nemafomite (zvishandiso, shangu, mota)
– Mhepo inobhururuka/aerosol (semuenzaniso furuwenza)
- Zvirwere zvakaita seumhutu, zvikwekwe, kana nhunzi
- Kubva kumubereki kuenda kumwana
Imwe pfungwa inokosha ndeye nhamba yekutanga yekubereka (R0), inova huwandu hwehutachiona hwechipiri hunokonzerwa nemunhu mumwe chete muvanhu vane chirwere ichi. Kana R0 > 1, chirwere ichi chingangowedzera; kana R0 < 1, chirwere ichi chichadzikira. Nzira dzekudzora dzakadai sekubaiwa majekiseni, kuvharirwa kwevanhu, uye kuwedzera kuchengetedzwa kwezvirwere zvine chinangwa chekuderedza kukosha kweR0.
5. Zvinhu Zvinokonzera Njodzi uye Kuferefeta Kwechirwere
Epidemiology ine chinangwa chekuona zvinhu zvinokonzera njodzi zvinowedzera mukana wezvirwere . Zvinhu zvinokonzera njodzi mumishonga yemhuka zvinogona kusanganisira:
- Zvinhu zvinotungamira: kuwanda kwemakeji, kutenderera kwemakeji, kuchena
– Zvinhu zvinokonzera chikafu: kusvibiswa kwe mycotoxin, kuchinja kamwe kamwe kwekudya
- Zvinhu zvinokonzeresa kufamba: kufamba kwemhuka, kuunzwa kwemhuka itsva pasina kuiswa mudzimba dzekuvharira mhuka
– Zvinhu zvinokonzeresa nharaunda: mwaka wemvura, mafashamo, kuchinja kwakanyanya kwekushisa
Kana huwandu hwezvirwere hukawedzera, kuferefeta kwechirwere kunoitwa nematanho anotevera: kusimbisa kuongororwa, kusimbisa kupararira kwechirwere, kutsanangura nyaya yacho, kufungidzira hukuru hwechirwere, kuronga kupararira kwacho (nguva yemunhu-nzvimbo, kana mumhuka: nguva yeboka-nzvimbo), kuyedza fungidziro nezvezvinhu zvinokonzera chirwere, uye kuita matanho ekudzora. Mukurima zvipfuyo, matanho ekukurumidza akadai sekuparadzanisa, kurambidza kufamba, kubvisa utachiona, uye kurapwa kwevanhu vakawanda zvinogona kudzivirira kurasikirwa kukuru.
6. Kutarisa, Kuchengetedzwa Kwezvinhu Zvakaipa, uye Kudzivirira
Kuongororwa kwechirwere inzira yekuongororwa yakarongeka uye inoenderera mberi. Kuongororwa kwechirwere kunogona kuitwa pasina kupindira (mishumo yenguva dzose) kana kuti pasina kupindira (kutsvaga nyaya yakarongwa uye kutora sampuli). Mukurapa kwemhuka, kuongororwa kwechirwere kunosanganisirawo kuongororwa kwemasero, kuongororwa kwePCR, uye kuongororwa kweante-mortem uye post-mortem panzvimbo dzekuurayira.
Kuchengetedzwa kwezvinhu zvipenyu ndiyo hwaro hwekudzivirira zvirwere mumapurazi. Mitemo yayo inosanganisira:
- Kuderedza kupinda kwezvirwere (kudzora kupinda kwemhuka, kupatsanura mhuka itsva)
– Deredza kupararira kwenzvimbo mupurazi (nzvimbo dzakachena-dzakasviba, kuvhiyiwa kwemishonga nguva dzose)
- Wedzera kuramba kwemurwere (kubaiwa nhomba, kudya kwakakwana, kugadzirisa kushushikana)
Chirongwa chakanaka chekudzivirira mhuka chinofanira kuenderana nerudzi rwezvipfuyo, huwandu hwebhizinesi, uye njodzi dzakati wandei dziri munzvimbo iyoyo.
7. Basa reEpidemiology muOne Health
Zvirwere zvakawanda zvemhuka zvine simba rakananga pavanhu. Zvirwere zvemhuka zvakaita sechimbwamupengo, anthrax, toxoplasmosis, uye furuwenza yeshiri zvinoda nzira dzakasiyana-siyana. Kuongororwa kwezvirwere zvemhuka kunobatsira pakuona zvirwere zviri kubuda, kudzora kubuda kwezvirwere, uye kuronga njodzi munharaunda. Kushanda pamwe chete pakati pevanachiremba vemhuka, nyanzvi dzehutano hwevanhu, uye nyanzvi dzezvakatipoteredza kwakakosha pakugadzirisa njodzi yezvirwere zvinotapukira zvinogona kupararira mumarudzi akasiyana.
Mhedziso
Nheyo huru dze epidemiology mukurapa kwemhuka dzinosanganisira kunzwisisa chirwere sechiitiko chehuwandu hwevanhu, kuyera kuwanda kwezvirwere uye kupararira kwazvo, kuongorora epidemiological triad, uye kuidzora kuburikidza nekutarisa, kuchengetedzeka kwezvinhu zvipenyu, uye kupindira kwakavakirwa panjodzi. Nzira ye epidemiology inobvumira kuita sarudzo dzakanangana, kuderedza kurasikirwa kwehupfumi, kuvandudza kugara zvakanaka kwemhuka, uye kuderedza njodzi dzemhuka kuvanhu. Pakupedzisira, epidemiology yemhuka haisi chishandiso chekuongorora chete asiwo hwaro hwemaitiro emazuva ano ehutano hwemhuka akabatanidzwa nehutano hwevanhu uye kuchengetedzeka kwezvakatipoteredza.
