Aive munaGunyana 2018, uye Vandenberg, panguva iyoyo ane makore makumi matanhatu nemanomwe, anga achinzwa zvishoma "pasi pemamiriro ekunze" kwemazuva mashoma, sekunge aive nefuruu, akadaro.
Akatanga kuzvimba uropi. Akatadza kuverenga nekunyora. Maoko nemakumbo zvakanga zvave chiveve nekuoma mitezo.
Kunyangwe zhizha rino rakaona hutachiona hwekutanga hwemunharaunda mumakumi maviri emakore echimwe chirwere chine chekuita neumhutu, marariya, hutachiona hweWest Nile uye umhutu hunohuparadzira izvo zviri kunyanya kunetsa vakuru vehutano.
Roxanne Connelly, chiremba wezvipembenene paCenters for Disease Control and Prevention (CDC), akati zvipembenene, rudzi rweumhutu hunodaidzwa kuti Culex, ndezveCenters for Disease Control and Prevention (CDC) "inonyanya kunetsa mukondinendi. Nyika dzakabatana "
Mwaka wegore rino wekunaya kwemvura zvisina kujairika nekuda kwekunaya kwemvura uye sinou inonyungudika, pamwe nekupisa kwakanyanya, zvinoita kunge zvakonzera kuwanda kweumhutu.
Uye maererano nemasayendisiti eCDC, umhutu uhu huri kuramba huchiramba mishonga yezvipembenene inowanikwa mumapfapfaidzo akawanda anoshandiswa neveruzhinji kuuraya umhutu nemazai ahwo.
“Hachisi chiratidzo chakanaka,” akadaro Connelly. "Tiri kurasikirwa nemamwe maturusi atinowanzo shandisa kudzora umhutu."
PaCenters for Disease Control and Prevention's Insect Laboratory muFort Collins, Colorado, kumusha kune makumi ezviuru zveumhutu, timu yaConnelly yakaona kuti Umhutu hweCulex hwakararama kwenguva yakareba mushure mekusangana neumhutu.mishonga yezvipembenene.
"Unoda chigadzirwa chinovavhiringa, kwete," Connelly akadaro, achinongedza bhodhoro reumhutu. Vanhu vakawanda vachiri kubhururuka.
Ongororo dzemurabhoritari hadzina kupikisa mishonga yezvipembenene inowanzoshandiswa nevanhu kudzinga umhutu pavanenge vachifamba nemamwe mabasa ekunze. Connelly akati vari kuramba vachiita zvakanaka.
Asi zvipembenene zvazvinova nesimba kupfuura mishonga yezvipembenene, nhamba yazvo iri kuwedzera mune dzimwe nzvimbo dzenyika.
Kubva muna 2023, kwave ne69 nyaya dzevanhu dzehutachiona hweWest Nile dzakataurwa muUnited States, maererano neCenters for Disease Control and Prevention. Izvi zviri kure nerekodhi: muna 2003, 9,862 makesi akanyorwa.
Asi makumi maviri emakore gare gare, humhutu hwakawanda hunoreva mukana mukuru wekuti vanhu vacharumwa uye kurwara. Mhosva muWest Nile dzinowanzokwira muna Nyamavhuvhu naGunyana.
"Iyi ingori mavambo ekuti tichaona sei West Nile ichitanga kukura muUnited States," akadaro Dr. Erin Staples, chiremba wechirwere chechirwere paCenters for Disease Control and Prevention laboratory muFort Collins. “Tinotarisira kuti nyaya dzicharamba dzichiwedzera mumavhiki mashoma anotevera.
Semuenzaniso, 149 misquito misungo muMaricopa County, Arizona, yakaongororwa hutachiona hweWest Nile gore rino, zvichienzaniswa nesere muna 2022.
John Townsend, vector control maneja weMaricopa County Environmental Services, akati mvura yakamira kubva mukunaya kwemvura zhinji yakasanganiswa nekupisa kwakanyanya kunoratidzika kunge kuri kuita kuti zvinhu zvinyanye kuipa.
“Mvura iripo ichangoibva kuti umhutu hukandira mazai,” akadaro Townsend. "Umhutu hunochechenya nekukurumidza mumvura inodziya - mukati memazuva matatu kusvika mana, zvichienzaniswa nemavhiki maviri mumvura inotonhorera," akadaro.
Kunyorova zvisina kujairika June muLarimer County, Colorado, uko kune Fort Collins lab, zvakakonzerawo "kuwanda kusati kwamboitika" kweumhutu hunogona kutapurira hutachiona hweWest Nile, akadaro Tom Gonzalez, director wezvehutano mudunhu iri.
County data inoratidza kuti kune kashanu umhutu muWest Nile gore rino kupfuura gore rapfuura.
Connelly akati kukura kwehupfumi mune dzimwe nzvimbo dzenyika "kwakanyanya." “Zvakasiyana nezvatakaona mumakore mashoma apfuura.”
Sezvo utachiona hweWest Nile hwakatanga kuwanikwa muUnited States muna 1999, hwava chirwere chinotapuriranwa neumhutu zvakanyanya munyika. Staples akati zviuru zvevanhu zvinotapukirwa gore rega rega.
West Nile haiparadzirwe kubva kumunhu kuenda kumunhu kuburikidza nekungosangana. Hutachiona uhu hunotapurirwa neumhutu hweCulex chete. Tupukanana uhu hunotapukira pahunoruma shiri dzinenge dzarwara dzobva dzatapurira utachiona kuvanhu kuburikidza nekumwe kuruma.
Vanhu vazhinji havambonzwi chero chinhu. Maererano neCDC, mumwe muvanhu vashanu anonzwa fivha, kutemwa nemusoro, kurwadza kwemuviri, kurutsa uye manyoka. Zviratidzo zvinowanzoonekwa mazuva 3-14 mushure mekurumwa.
Mumwe muvanhu zana nemakumi mashanu vakatapukirwa nehutachiona hweWest Nile anoita matambudziko akakomba, kusanganisira rufu. Chero ani zvake anogona kurwara zvakanyanya, asi Staples akati vanhu vanopfuura makumi matanhatu uye vanhu vane hutano huri panjodzi vari panjodzi huru.
Makore mashanu mushure mekuonekwa kuti ane West Nile, Vandenberg akawanazve hunyanzvi hwake kuburikidza nekurapa kwakanyanya kwemuviri. Zvisinei, makumbo ake akaramba achiita chiveve, zvichimumanikidza kuvimba nemadondoro.
Vandenberg paakadonha mangwanani iwayo munaGunyana 2018, aive munzira kuenda kumariro eshamwari yake yaive yafa nekunetsekana nehutachiona hweWest Nile.
Chirwere ichi “chinogona kuve chakakomba zvakanyanya uye vanhu vanofanirwa kuzviziva. Inogona kushandura hupenyu hwako,” akadaro.
Nepo kushorwa kwemishonga yezvipembenene kuchikwira, timu yaConnolly yakaona kuti mishonga inodzinga zvipembenene inoshandiswa nevanhu kunze ichiri kushanda. Maererano neCenters for Disease Control and Prevention (CDC), zvakanakisisa kushandisa mishonga yezvipembenene ine zvinhu zvakadai seDEET uye picaridin.
