KwakungoSeptemba ka-2018, kwaye uVandenberg, owayeneminyaka engama-67 ngoko, wayeziva "phantsi kwemozulu" kancinane iintsuku ezimbalwa, ngathi unomkhuhlane, watsho.
Waba nokudumba kwengqondo.Wayengakwazi ukufunda nokubhala.Iingalo nemilenze yakhe yayindindisholo ngenxa yokukhubazeka.
Nangona eli hlotyeni labona usulelo lokuqala lwasekhaya kwiminyaka engamashumi amabini yesinye isifo esinxulumene nengcongconi, isifo seengcongconi, yintsholongwane ye-West Nile kunye neengcongconi ezisasaza ukuba zixhalabile ngamagosa ezempilo e-federal.
URoxanne Connelly, ugqirha wezinambuzane kwezonyango kumaZiko oLawulo lweSifo kunye noThintelo (CDC), uthe izinambuzane, uhlobo lwengcongconi olubizwa ngokuba yiCulex, ngamaZiko oLawulo lweSifo kunye noThintelo (CDC) “owona mba uxhalabisayo ngoku kwilizwekazi. Amazwe Amanyene "
Ixesha lonyaka elineemvula ezingaqhelekanga ngenxa yemvula nekhephu elinyibilikayo, lidityaniswa nobushushu obugqithiseleyo, kubonakala ngathi kukhokelele ekwandeni kweengcongconi.
Kwaye ngokutsho kwezazinzulu ze-CDC, ezi ngcongconi ziya zixhathisa ngakumbi kwizitshabalalisi ezifumaneka kwizitshizi ezininzi ezisetyenziswa luluntu ukubulala iingcongconi namaqanda azo.
“Asilophawu lulungileyo olo,” watsho uConnelly.“Silahlekelwa zezinye zezixhobo esiqhele ukuzisebenzisa ukulawula iingcongconi ezosulelekileyo.”
Kumaziko oLawulo lweZifo kunye noThintelo lweLebhu yezinambuzane eFort Collins, eColorado, ikhaya lamashumi amawaka eengcongconi, iqela likaConnelly lafumanisa ukuba iingcongconi zaseCulex zaziphila ixesha elide emva kokuchanabeka kwimichiza yokubulala izinambuzane.
“Ufuna imveliso ebabhidayo, hayi,” utshilo uConnelly, ekhomba ibhotile yeengcongconi ezivezwe kwimichiza.Abantu abaninzi basabhabha.
Uvavanyo lwaselabhoratri alufumananga ukuxhathisa amayeza okubulala izinambuzane adla ngokusetyenziswa ngabantu ukugxotha iingcongconi ngelixa benyuka intaba kunye neminye imisebenzi yangaphandle.UConnelly uthe basaqhubeka nokwenza kakuhle.
Kodwa njengoko izinambuzane zisiba namandla ngakumbi kunezibulali-zinambuzane, inani lazo liya lintinga kweminye imimandla yelizwe.
Ukususela ngo-2023, kukho iimeko ze-69 zabantu zentsholongwane ye-West Nile echazwe e-United States, ngokutsho kwamaZiko oLawulo lweSifo kunye noThintelo.Oku kude nerekhodi: ngo-2003, amatyala angama-9,862 arekhodwa.
Kodwa kumashumi amabini eminyaka kamva, iingcongconi ezininzi zithetha ithuba elikhulu lokuba abantu baya kulunywa kwaye bagule.Amatyala eWest Nile aye ancopho ngo-Agasti nangoSeptemba.
"Esi sisiqalo nje sendlela esiya kubona ngayo iWest Nile iqala ukukhula e-United States," utshilo uGqr. Erin Staples, i-epidemiologist yezonyango kwiziko lebhubhoratri yoLawulo lweSifo kunye noThintelo eFort Collins.“Silindele ukuba amatyala anyuke ngokuthe chu kwezi veki zimbalwa zizayo.
Umzekelo, i-149 imigibe yeengcongconi kwiNqila yaseMaricopa, eArizona, ivavanywe ukuba inentsholongwane ye-West Nile kulo nyaka, xa kuthelekiswa nezisibhozo ngo-2022.
UJohn Townsend, umphathi wolawulo lwe vector kwi Maricopa County Environmental Services, uthe amanzi amileyo aphuma kwiimvula ezinkulu adityaniswe nobushushu obugqithisileyo abonakala esenza imeko ibe mandundu.
“Amanzi apho asele evuthiwe ukuba iingcongconi zibeke amaqanda,” utshilo uTownsend."Iingcongconi ziqandusela ngokukhawuleza emanzini afudumeleyo - kwiintsuku ezintathu ukuya kwezine, xa kuthelekiswa neeveki ezimbini emanzini apholileyo," watsho.
Unyaka omanzi ngokungaqhelekanga ngoJuni eLarimer County, eColorado, apho ikhoyo ilebhu yaseFort Collins, kukwakhokelele “kubuninzi obungazange bubonwe ngaphambili” beengcongconi ezinokusasaza intsholongwane ye-West Nile, utshilo uTom Gonzalez, umlawuli wezempilo woluntu.
Idatha yesithili ibonisa ukuba kukho iingcongconi eziphindwe kahlanu eWest Nile kulo nyaka kunonyaka ophelileyo.
UConnelly uthe ukukhula koqoqosho kwezinye iindawo zelizwe "kuxhalabisa kakhulu."“Yahlukile koko sikubonileyo kule minyaka imbalwa idlulileyo.”
Ekubeni intsholongwane iWest Nile yaqala ukufunyanwa eUnited States ngowe-1999, iye yaba sesona sifo sixhaphakileyo esithwaxwa ziingcongconi kweli lizwe.UStaples uthe amawakawaka abantu bayosuleleka minyaka le.
I-West Nile ayisasazeki ukusuka komnye umntu ukuya komnye ngoqhagamshelwano oluqhelekileyo.Intsholongwane isasazwa kuphela ziingcongconi zaseCulex.Ezi zinambuzane zosuleleka xa ziluma iintaka ezigulayo zize zisasaze intsholongwane ebantwini ngokulunywa okunye.
Abantu abaninzi abaziva nto.Ngokutsho kweCDC, umntu omnye kwabahlanu uba nomkhuhlane, intloko ebuhlungu, iintlungu zomzimba, ukugabha kunye norhudo.Iimpawu zidla ngokuvela kwiintsuku ezi-3-14 emva kokulunywa.
Umntu omnye kwabayi-150 abosulelwe yintsholongwane ye-West Nile uba neengxaki ezinzulu, kuquka nokufa.Nabani na unokugula kakhulu, kodwa uStaples uthe abantu abangaphezu kweminyaka engama-60 kunye nabantu abaneemeko zempilo eziphantsi basemngciphekweni omkhulu.
Kwiminyaka emihlanu emva kokufunyaniswa ukuba uneWest Nile, iVandenberg iphinde yafumana izakhono zakhe ezininzi ngonyango olumandla.Noko ke, imilenze yakhe yaqhubeka isiba ndindisholo, nto leyo eyayimnyanzela ukuba athembele ngeentonga.
Xa iVandenberg yawa ngaloo ntsasa ngoSeptemba ka-2018, wayesendleleni eya kumngcwabo womhlobo wakhe owayesweleke ngenxa yentsholongwane ye-West Nile.
Esi sifo “sinokuba sibi kakhulu kwaye abantu kufuneka bayazi loo nto.Ingatshintsha ubomi bakho,” utshilo.
Ngelixa ukuxhathisa amayeza okubulala izinambuzane kusenokukhula, iqela likaConnolly lifumanise ukuba izigxothi eziqhelekileyo ezisetyenziswa ngabantu ngaphandle zisasebenza.Ngokutsho kwamaZiko oLawulo lweZifo kunye noThintelo (CDC), kukulungele ukusebenzisa i-pesticides equkethe izithako ezifana ne-DEET kunye ne-picaridin.
