Yaiva Gunyana 2018, uye Vandenberg, uyo aiva nemakore 67 panguva iyoyo, akanga achinzwa "kushushikana" kwemazuva mashoma, sekunge aive nefuruwenza, akadaro.
Akatanga kuzvimba uropi. Akarasikirwa nekwaniso yekuverenga nekunyora. Maoko nemakumbo ake zvakanga zvapera simba nekuda kwekuoma mitezo.
Kunyangwe zhizha rino rakaona hutachiona hwekutanga hwemuno mumakumi maviri emakore echirwere chimwe chine chekuita neumhutu, malaria, hutachiona hweWest Nile pamwe neumhutu huri kuuparadzira ndizvo zvinonyanya kushungurudza vakuru vehutano vehurumende.
Roxanne Connelly, nyanzvi yezvipembenene paCenters for Disease Control and Prevention (CDC), akati zvipembenene izvi, rudzi rweumhutu hunonzi Culex, ndezveCenters for Disease Control and Prevention (CDC) "dambudziko rinonyanya kunetsa muUnited States parizvino"
Mwaka wegore rino wemvura isingawanzoitika nekuda kwemvura uye sinou inonyunguduka, pamwe chete nekupisa kwakanyanya, zvinoita sekunge zvakakonzera kuwanda kwehuwandu hweumhutu.
Uye sekureva kwevasayendisiti veCDC, umhutu uhwu huri kuramba huchirwisa mishonga yekuuraya zvipembenene inowanikwa mumapfapfaidzo akawanda anoshandiswa neveruzhinji kuuraya umhutu nemazai ahwo.
"Icho hachisi chiratidzo chakanaka," akadaro Connelly. "Tiri kurasikirwa nezvimwe zvezvishandiso zvatinowanzoshandisa kudzora umhutu hwakapararira."
PaCenters for Disease Control and Prevention's Insect Laboratory muFort Collins, Colorado, musha wemakumi ezviuru zveumhutu, chikwata chaConnelly chakaona kuti umhutu hweCulex hunorarama kwenguva yakareba mushure mekusangana nemishonga yezvipembenene.
"Unoda chinhu chinovavhiringidza, kwete chinovakanganisa," akadaro Connelly, achinongedzera kubhodhoro reumhutu hwakasangana nemakemikari aya. Vanhu vazhinji vachiri kubhururuka.
Kuedza kwemurabhoritari hakuna kuwana mushonga wezvipembenene unoshandiswa nevanhu kudzinga umhutu pavanenge vachifamba netsoka uye mune zvimwe zviitiko zvekunze. Connelly akati uchiri kushanda zvakanaka.
Asi sezvo zvipembenene zvichiva nesimba kupfuura mishonga yekuuraya zvipembenene, huwandu hwazvo huri kuwedzera mune dzimwe nzvimbo dzenyika.
Kubva mugore ra2023, kwave nevanhu makumi matanhatu nevapfumbamwe vane hutachiona hweWest Nile hwakataurwa muUnited States, zvichienderana neCenters for Disease Control and Prevention. Izvi hazvisi kure nerekodhi: muna 2003, vanhu 9,862 vakanyoreswa.
Asi mushure memakore makumi maviri, umhutu hwakawanda hunoreva mukana mukuru wekuti vanhu varumwe uye varware. Nyaya dzemhombwe muWest Nile dzinowanzo svika muna Nyamavhuvhu naGunyana.
"Uku kungori kutanga kwekuti tichaona sei West Nile ichitanga kukura muUnited States," akadaro Dr. Erin Staples, nyanzvi yezvirwere zvemabhakitiriya paCenters for Disease Control and Prevention laboratory muFort Collins. "Tinotarisira kuti huwandu hwevanhu vanobatwa nechirwere ichi hucharamba huchiwedzera mumavhiki mashoma anotevera."
Semuenzaniso, misungo yeumhutu 149 muMaricopa County, Arizona, yakaongororwa yakawanikwa ine hutachiona hweWest Nile gore rino, zvichienzaniswa nemisere muna 2022.
John Townsend, maneja wezvekudzora majekiseni kuMaricopa County Environmental Services, akati mvura yakamira kubva pakunaya kwemvura yakawanda pamwe chete nekupisa kwakanyanya zvinoita sekunge kuri kuita kuti mamiriro acho ezvinhu awedzere kuipa.
"Mvura yemuno yatoibva kuti umhutu hukwanise kuisa mazai," akadaro Townsend. "Umhutu hunokasira kumera mumvura inodziya - mukati memazuva matatu kusvika mana, zvichienzaniswa nemavhiki maviri mumvura inotonhorera," akadaro.
Kunaya kwemvura kusingawanzoitika muna Chikumi muLarimer County, Colorado, uko kune rabhoritari yeFort Collins, kwakakonzerawo "kuwanda kusati kwamboitika" kweumhutu hunogona kutapurira hutachiona hweWest Nile, akadaro Tom Gonzalez, mukuru wehutano hweveruzhinji wedunhu.
Ruzivo rwedunhu runoratidza kuti umhutu hwacho hwakapetwa kashanu muWest Nile gore rino kupfuura gore rapfuura.
Connelly akati kukura kwehupfumi mune dzimwe nzvimbo dzenyika "kunonetsa zvikuru." "Zvakasiyana nezvatakaona mumakore mashoma apfuura."
Kubva pakatanga kuwanikwa hutachiona hweWest Nile muUnited States muna 1999, hwave chirwere chinowanzo pararira neumhutu munyika iyi. Staples akati zviuru zvevanhu zvinobatwa nechirwere ichi gore rega rega.
West Nile haiparadzirwi kubva kumunhu kuenda kune mumwe munhu kuburikidza nekubata vanhu zvisina tsarukano. Utachiona uhwu hunongotapuriranwa neumhutu hweCulex chete. Utachiona uhwu hunotapuriranwa kana hukaruma shiri dzinorwara uye hwozotapurirana hutachiona kuvanhu kuburikidza nekurumwazve.
Vanhu vazhinji havambonzwi chero chinhu. Sekureva kweCDC, munhu mumwe chete pavanhu vashanu anonzwa fivha, musoro, kurwadziwa kwemuviri, kurutsa uye manyoka. Zviratidzo zvinowanzoonekwa mazuva matatu kusvika gumi nemana mushure mekurumwa.
Munhu mumwe chete pavanhu zana nemakumi mashanu vane hutachiona hweWest Nile anowana matambudziko akakomba, kusanganisira kufa. Munhu wese anogona kurwara zvakanyanya, asi Staples akati vanhu vane makore anopfuura makumi matanhatu nevanhu vane matambudziko ehutano ari panjodzi huru.
Makore mashanu mushure mekuonekwa kuti ane chirwere cheWest Nile, Vandenberg akadzoka patsva muhunyanzvi hwake hwakawanda kuburikidza nekurapwa kwakasimba kwemuviri. Zvisinei, makumbo ake akaramba achishaya simba, zvichimumanikidza kushandisa madondoro.
Vandenberg paakadonha mangwanani iwayo munaGunyana 2018, akanga ari munzira kuenda kumariro eshamwari yake yakanga yafa nekuda kwezvirwere zvehutachiona hweWest Nile.
Chirwere ichi "chinogona kuva chakakomba zvikuru uye vanhu vanofanira kuziva izvozvo. Chinogona kuchinja hupenyu hwako," akadaro.
Kunyange hazvo kuramba mishonga inouraya zvipembenene kuri kuwedzera, chikwata chaConnolly chakaona kuti mishonga inouraya zvipembenene inoshandiswa nevanhu panze ichiri kushanda. Sekureva kweCenters for Disease Control and Prevention (CDC), zvakanaka kushandisa mishonga inouraya zvipembenene ine zvinhu zvakaita seDEET nepicaridin.
