Udzudzu womwe umanyamula kachilombo ka West Nile umayamba kukana mankhwala ophera tizilombo, malinga ndi CDC.

Munali Seputembara 2018, ndipo Vandenberg, yemwe panthawiyo anali ndi zaka 67, anali kumva pang'ono "nyengo" kwa masiku angapo, ngati ali ndi chimfine, adatero.
Anayambitsa kutupa kwa ubongo.Anasiya kuwerenga ndi kulemba.Mikono ndi miyendo yake inali itachita dzanzi chifukwa cha kufa ziwalo.
Ngakhale kuti chilimwechi chinawona matenda oyambirira a m'deralo m'zaka makumi awiri za matenda ena okhudzana ndi udzudzu, malungo, ndi kachilombo ka West Nile ndi udzudzu umene umafalitsa zomwe zimadetsa nkhawa kwambiri akuluakulu a zaumoyo.
Roxanne Connelly, katswiri wazachipatala ku Centers for Disease Control and Prevention (CDC), adati tizilombo, mtundu wa udzudzu wotchedwa Culex, ndi wa Centers for Disease Control and Prevention (CDC) "vuto lomwe likukhudzidwa kwambiri pano padziko lonse lapansi. United States "
Nyengo yamvula yachaka chino chifukwa cha mvula komanso chipale chofewa, komanso kutentha kwambiri, zikuwoneka kuti zachititsa kuti udzudzu uchulukane.
Ndipo malinga ndi kunena kwa asayansi a CDC, udzudzu umenewu ukukula kwambiri ndi mankhwala ophera tizilombo opezeka m’mankhwala opopera omwe amagwiritsidwa ntchito ndi anthu kupha udzudzu ndi mazira ake.
Connelly anati: “Chimenecho si chizindikiro chabwino."Tikutaya zida zina zomwe timagwiritsa ntchito poletsa udzudzu womwe uli ndi kachilomboka."
Ku Centers for Disease Control and Prevention's Insect Laboratory ku Fort Collins, Colorado, komwe kumakhala udzudzu masauzande ambiri, gulu la Connelly lidapeza kuti udzudzu wa Culex umakhala nthawi yayitali pambuyo pokhudzidwa ndi udzudzu.mankhwala ophera tizilombo.
"Mukufuna chinthu chomwe chimawasokoneza, osatero," adatero Connelly, akuloza botolo la udzudzu lomwe lili ndi mankhwalawo.Anthu ambiri amawulukabe.
Kufufuza kwa labotale sikunapezepo kukana mankhwala ophera tizilombo omwe nthawi zambiri anthu amawagwiritsa ntchito pothamangitsa udzudzu poyenda ndi ntchito zina zapanja.Connelly adati akupitiliza kuchita bwino.
Koma pamene tizilombo tayamba kukhala ndi mphamvu kuposa mankhwala ophera tizilombo, chiŵerengero chawo chikuwonjezeka m’madera ena a dzikolo.
Pofika chaka cha 2023, pakhala pali anthu 69 omwe adadwala kachilombo ka West Nile ku United States, malinga ndi Centers for Disease Control and Prevention.Izi siziri kutali ndi mbiri: mu 2003, milandu 9,862 idalembedwa.
Koma patatha zaka 20, udzudzu wochuluka ukutanthauza kuti anthu ambiri adzalumidwa ndi kudwala.Milandu ku West Nile nthawi zambiri imakhala pachimake mu Ogasiti ndi Seputembala.
"Ichi ndi chiyambi chabe cha momwe tidzaonera West Nile ikuyamba kukula ku United States," anatero Dr. Erin Staples, katswiri wa zachipatala ku labotale ya Centers for Disease Control and Prevention ku Fort Collins."Tikuyembekeza kuti milandu ichuluke pang'onopang'ono m'masabata angapo otsatira.
Mwachitsanzo, misampha 149 ya udzudzu ku Maricopa County, Arizona, idapezeka kuti ili ndi kachilombo ka West Nile chaka chino, poyerekeza ndi eyiti mu 2022.
John Townsend, woyang'anira ma vector ku Maricopa County Environmental Services, adati madzi osasunthika kuchokera kumvula yamkuntho kuphatikiza ndi kutentha kwakukulu akuwoneka kuti akupangitsa kuti zinthu ziipireipire.
"Madzi kumeneko ndi okhwima kuti udzudzu ungayikire mazira," adatero Townsend."Udzudzu umaswa mofulumira m'madzi ofunda - mkati mwa masiku atatu kapena anayi, poyerekeza ndi masabata awiri m'madzi ozizira," adatero.
Kumvula modabwitsa mu June ku Larimer County, Colorado, komwe kuli labu ya Fort Collins, kudadzetsanso "kuchuluka" kwa udzudzu womwe ungathe kufalitsa kachilombo ka West Nile, atero a Tom Gonzalez, mkulu wa zaumoyo m'boma.
Deta ya County ikuwonetsa kuti kuli udzudzu wochulukirapo kasanu ku West Nile chaka chino kuposa chaka chatha.
Connelly adati kukula kwachuma m'madera ena a dziko "ndikokhudza kwambiri."“N’zosiyana ndi zimene taona m’zaka zingapo zapitazi.”
Popeza kuti kachilombo ka West Nile kanapezeka koyamba ku United States mu 1999, matendawa afala kwambiri m’dzikoli.Staples adati anthu masauzande ambiri amadwala chaka chilichonse.
West Nile sikufalikira kuchokera kwa munthu kupita kwa munthu kudzera mukulankhulana wamba.Kachilomboka kamafala kokha ndi udzudzu wa Culex.Tizilombo timeneti timadwala tikaluma mbalame zodwala ndipo kenako timapatsira anthu kachilomboka kudzera mu kuluma kwina.
Anthu ambiri samamva kalikonse.Malinga ndi CDC, mmodzi mwa anthu asanu amadwala malungo, mutu, kupweteka kwa thupi, kusanza ndi kutsekula m'mimba.Zizindikiro zambiri zimawonekera patatha masiku 3-14 mutaluma.
Mmodzi mwa anthu 150 omwe ali ndi kachilombo ka West Nile amakhala ndi zovuta zambiri, kuphatikizapo imfa.Aliyense akhoza kudwala kwambiri, koma Staples adati anthu opitilira zaka 60 komanso anthu omwe ali ndi thanzi labwino ali pachiwopsezo chachikulu.
Patatha zaka zisanu atapezeka ndi matenda a West Nile, Vandenberg wapezanso maluso ambiri chifukwa cha chithandizo chamankhwala cholimbitsa thupi.Komabe, miyendo yake inapitiriza kuchita dzanzi, moti ankangodalira ndodo.
Vandenberg atakomoka m'mawa womwewo mu Seputembara 2018, anali panjira yopita kumaliro a mnzake yemwe adamwalira ndi kachilombo ka West Nile.
Matendawa “akhoza kukhala oopsa kwambiri ndipo anthu ayenera kudziwa zimenezo.Ikhoza kusintha moyo wanu,” adatero.
Ngakhale kuti kukana mankhwala ophera tizilombo kukuchulukirachulukira, gulu la Connolly lapeza kuti zothamangitsa wamba zomwe anthu amagwiritsa ntchito panja zikadali zothandiza.Malingana ndi Centers for Disease Control and Prevention (CDC), ndi bwino kugwiritsa ntchito mankhwala ophera tizilombo omwe ali ndi zinthu monga DEET ndi picaridin.
