KwakunguSepthemba 2018, kanti uVandenberg, ngaleso sikhathi owayeneminyaka engama-67 ubudala, wayezizwa “ngaphansi kwesimo sezulu” izinsuku ezimbalwa, sengathi unomkhuhlane, kusho yena.
Waba nokuvuvukala kobuchopho.Walahlekelwa ikhono lokufunda nokubhala.Izingalo nemilenze yakhe yayindikindiki ngenxa yokukhubazeka.
Nakuba kuleli hlobo kubonakale ukutheleleka kokuqala kwendawo emashumini amabili eminyaka kwesinye isifo esihlobene nomiyane, umalaleveva, yigciwane laseWest Nile kanye nomiyane abalisabalalisa okukhathaza kakhulu izikhulu zezempilo zikahulumeni.
URoxanne Connelly, isazi sezinambuzane zezokwelapha eCenters for Disease Control and Prevention (CDC), uthe izinambuzane, uhlobo lomiyane obizwa ngokuthi i-Culex, ezeCenters for Disease Control and Prevention (CDC) “indaba ethinta kakhulu njengamanje ezwenikazi. I-united states "
Isizini yalo nyaka enezimvula ngokungajwayelekile ngenxa yemvula neqhwa elincibilikayo, kuhlanganiswe nokushisa okunamandla, kubonakala kuholele ekwandeni komiyane.
Futhi ngokusho kososayensi be-CDC, laba omiyane baqala ukumelana nezibulala-zinambuzane ezitholakala ezifuthoni eziningi ezisetshenziswa umphakathi ukubulala omiyane namaqanda abo.
“Akulona uphawu oluhle lolo,” kusho uConnelly."Silahlekelwa amanye amathuluzi esivame ukuwasebenzisa ukulawula omiyane abagcwele."
ECenters for Disease Control and Prevention’s Insect Laboratory eFort Collins, eColorado, okuyikhaya lamashumi ezinkulungwane zomiyane, ithimba likaConnelly lathola ukuthi omiyane baseCulex baphila isikhathi eside ngemva kokuchayeka ezinambuzaneni.
“Ufuna umkhiqizo obadidayo, awukwenzi lokho,” kusho uConnelly ekhomba ibhodlela lomiyane elichayeke kumakhemikhali.Abantu abaningi basandiza.
Ukuhlola kwaselabhorethri akutholanga ukumelana nezibulala-zinambuzane ezivame ukusetshenziswa abantu ukuxosha omiyane lapho beqwala izintaba neminye imisebenzi yangaphandle.UConnelly uthe basaqhubeka nokwenza kahle.
Kodwa njengoba izinambuzane ziba namandla kunezibulala-zinambuzane, inani lazo liyanda kwezinye izingxenye zezwe.
Kusukela ngo-2023, kube nezigameko zabantu ezingama-69 zokutheleleka ngegciwane le-West Nile ezibikwe e-United States, ngokusho kweCenters for Disease Control and Prevention.Lokhu kude nerekhodi: ngo-2003, kwaqoshwa amacala ayi-9,862.
Kodwa ngemva kweminyaka engamashumi amabili, omiyane abengeziwe basho amathuba amakhulu okuthi abantu bazolunywa futhi bagule.Amacala eWest Nile avamise ukuba phezulu ngo-Agasti noSepthemba.
"Lesi yisiqalo sokuthi sizobona kanjani iWest Nile iqala ukuthuthuka e-United States," kusho uDkt. Erin Staples, udokotela wezifo eziwumshayabhuqe wezokwelapha esikhungweni selabhorethri yeCenters for Disease Control and Prevention eFort Collins.“Silindele ukuthi amacala anyuke kancane emasontweni ambalwa ezayo.
Isibonelo, izicupho zomiyane eziyi-149 eMaricopa County, e-Arizona, zihlolwe ukuthi zinegciwane iWest Nile kulo nyaka, uma ziqhathaniswa neziyisishiyagalombili ngo-2022.
UJohn Townsend, oyimenenja elawula ama-vector eMaricopa County Environmental Services, uthe amanzi amile ezimvula ezinamandla ahambisana nokushisa okudlulele kubonakala enza isimo sibe sibi kakhulu.
“Amanzi akhona asevuthiwe ukuze omiyane bazalele amaqanda kuwo,” kusho u-Townsend."Omiyane bachanyuselwa ngokushesha emanzini afudumele - phakathi kwezinsuku ezintathu kuya kwezine, uma kuqhathaniswa namasonto amabili emanzini apholile," esho.
UJuni omanzi ngendlela engavamile eLarimer County, eColorado, lapho kutholakala khona ilebhu yaseFort Collins, kuphinde kwaholela “ebuningini obungakaze bubonwe” bomiyane abangasabalalisa leli gciwane laseWest Nile, kusho uTom Gonzalez, umqondisi wezempilo womphakathi kulesi sifunda.
Idatha yesifunda ibonisa ukuthi kunomiyane abaningi ngokuphindwe kahlanu eWest Nile kulo nyaka kunangonyaka odlule.
UConnelly uthe ukukhula komnotho kwezinye izingxenye zezwe "kuthinta kakhulu."“Kuhlukile kulokho esikubone eminyakeni embalwa edlule.”
Kusukela kwatholakala igciwane iWest Nile okokuqala e-United States ngo-1999, seliyisifo esivame kakhulu esithwalwa omiyane kuleli.UStaples uthe izinkulungwane zabantu zitheleleka minyaka yonke.
I-West Nile ayisakazwa isuka kumuntu iye komunye ngokuthintana nje.Igciwane lisakazwa kuphela omiyane be-Culex.Lezi zinambuzane zitheleleka lapho ziluma izinyoni ezigulayo bese zidlulisela igciwane kubantu ngokunye ukulunywa.
Abantu abaningi abazizwa lutho.Ngokusho kwe-CDC, umuntu oyedwa kwabahlanu uba nomkhuhlane, ikhanda elibuhlungu, ubuhlungu bomzimba, ukuhlanza kanye nesifo sohudo.Izimpawu zivame ukuvela ezinsukwini ezi-3-14 ngemuva kokulunywa.
Umuntu oyedwa kwabangu-150 abangenwe yigciwane iWest Nile uba nezinkinga ezinkulu, okuhlanganisa nokufa.Noma ngubani angagula kakhulu, kepha uStaples uthe abantu abangaphezu kweminyaka engama-60 kanye nabantu abanezimo zempilo ezingaphansi basengozini enkulu.
Ngemva kweminyaka emihlanu kwatholakala ukuthi une-West Nile, u-Vandenberg usephinde wathola amakhono akhe amaningi ngokwelashwa okuqinile komzimba.Nokho, imilenze yakhe yaqhubeka nokuba ndikindiki, okwamphoqa ukuba athembele ezindukuni.
Ngenkathi uVandenberg ewa ngalolo suku ekuseni ngoSepthemba 2018, wayesendleleni eya emngcwabeni womngane wakhe owayeshone ngenxa yezinkinga zegciwane laseWest Nile.
Lesi sifo “singaba sibi kakhulu futhi abantu badinga ukwazi lokho.Ingayishintsha impilo yakho,” kusho yena.
Nakuba ukumelana nezibulala-zinambuzane kungase kukhule, ithimba likaConnolly lithole ukuthi izixoxi ezivamile abantu abazisebenzisa ngaphandle zisasebenza.Ngokusho kweCenters for Disease Control and Prevention (CDC), kungcono ukusebenzisa izibulala-zinambuzane eziqukethe izithako ezifana ne-DEET ne-picaridin.
