Hari muri Nzeri 2018, kandi Vandenberg, wari ufite imyaka 67 icyo gihe, yari amaze iminsi mike yumva ameze nk'aho arwaye ibicurane.
Yatangiye kubyimba ubwonko. Yatakaje ubushobozi bwo gusoma no kwandika. Amaboko n'amaguru bye byari byacitse intege kubera ubumuga.
Nubwo muri iyi mpeshyi habaye ubwandu bwa mbere mu myaka makumyabiri ishize indi ndwara iterwa n’imibu, malariya, ni virusi ya West Nile n’imibu iyikwirakwiza ari byo bihangayikishije cyane abayobozi b’ubuzima ba leta.
Roxanne Connelly, inzobere mu by’udukoko mu kigo gishinzwe kurwanya no gukumira indwara (CDC), yavuze ko utwo dukoko, ubwoko bw’umubu witwa Culex, ari two “duhangayikishije cyane muri iki gihe muri Amerika.”
Ibihe by'imvura bidasanzwe by'uyu mwaka bitewe n'imvura n'urubura rushongeshejwe, hamwe n'ubushyuhe bwinshi, bisa nkaho byatumye imibu yiyongera cyane.
Kandi nk'uko abahanga mu bya siyansi ba CDC babivuga, iyi mibu irimo irushaho kurwanya imiti yica udukoko iboneka mu miti myinshi ikoreshwa n'abaturage mu kwica imibu n'amagi yayo.
Connelly yagize ati: “Icyo si ikimenyetso cyiza. Turimo gutakaza bimwe mu bikoresho dusanzwe dukoresha mu kurwanya imibu yanduye.”
Muri Laboratwari y’udukoko y’Ikigo gishinzwe kurwanya no gukumira indwara i Fort Collins, muri Colorado, ituwe n’imibu ibihumbi mirongo, itsinda rya Connelly ryasanze imibu ya Culex iramba nyuma yo guhura n’iyi mibu.imiti yica udukoko.
Connelly yagize ati: “Urashaka ikintu kibatera urujijo, ntabwo ari cyo kibatera urujijo.” Abantu benshi baracyaguruka.
Igerageza ryakorewe muri laboratwari ntiryagaragaje ko imiti yica udukoko ikunze gukoreshwa n'abantu mu kwirukana imibu mu gihe cyo gutembera no mu yindi mirimo yo hanze ikomeje kumera neza. Connelly yavuze ko ikomeje gukora neza.
Ariko uko udukoko turushaho kugira imbaraga kurusha imiti yica udukoko, umubare watwo ugenda wiyongera mu bice bimwe na bimwe by'igihugu.
Kugeza mu 2023, muri Leta Zunze Ubumwe za Amerika hamaze kugaragara abantu 69 banduye virusi ya West Nile, nk'uko Ikigo gishinzwe kurwanya no gukumira indwara kibitangaza. Ibi ntibiramenyekana: mu 2003, hagaragaye abantu 9.862 banduye virusi.
Ariko nyuma y’imyaka makumyabiri, imibu myinshi bivuze ko hari amahirwe menshi y’uko abantu bazarumwa no kurwara. Abarwayi bo muri West Nile bakunze kwiyongera muri Kanama na Nzeri.
“Iyi ni intangiriro gusa y’uko tuzabona West Nile itangiye gutera imbere muri Leta Zunze Ubumwe za Amerika,” ibi ni ibyatangajwe na Dr. Erin Staples, inzobere mu by’indwara z’ibyorezo muri laboratwari y’ikigo gishinzwe kurwanya no gukumira indwara i Fort Collins. “Twiteze ko abarwayi bakomeza kwiyongera mu byumweru bike biri imbere.”
Urugero, imitego 149 yo mu Karere ka Maricopa, muri Arizona, yagaragaye ko yanduye virusi ya West Nile uyu mwaka, ugereranyije n’imitego umunani yo mu 2022.
John Townsend, ushinzwe kugenzura ibidukikije muri Maricopa County Environmental Services, yavuze ko amazi ahagaze aturutse ku mvura nyinshi hamwe n'ubushyuhe bukabije asa n'aho ari byo bituma ibintu birushaho kuba bibi.
“Amazi yaho yeze cyane kugira ngo imibu itere amagi,” Townsend yagize ati: “Imibu irakura vuba mu mazi ashyushye – mu minsi itatu cyangwa ine, ugereranije n’ibyumweru bibiri mu mazi akonje.”
Tom Gonzalez, umuyobozi ushinzwe ubuzima rusange muri ako karere, yavuze ko imvura yaguye mu kwezi kwa Kamena mu Karere ka Larimer, muri Colorado, aho laboratwari ya Fort Collins iherereye, na yo yatumye habaho "ubwinshi budasanzwe" bw'imibu ishobora kwanduza virusi ya West Nile.
Amakuru y’akarere agaragaza ko muri West Nile uyu mwaka hari imibu yikubye inshuro eshanu ugereranyije n’umwaka ushize.
Connelly yavuze ko iterambere ry'ubukungu mu bice bimwe na bimwe by'igihugu “riteye impungenge cyane.” “Bitandukanye n'ibyo twabonye mu myaka mike ishize.”
Kuva virusi ya West Nile yavumburwa bwa mbere muri Leta Zunze Ubumwe za Amerika mu 1999, yabaye indwara ikwirakwizwa cyane muri iki gihugu. Staples yavuze ko abantu ibihumbi bandura buri mwaka.
Uruzi rwa Nile y'Iburengerazuba ntirwandura umuntu ku wundi binyuze mu gukoranaho bisanzwe. Uruzi rwa virusi rwandurira gusa mu mibu ya Culex. Utu dukoko twandura iyo turiye inyoni zirwaye hanyuma tugatera iyo virusi ku bantu binyuze mu kurumwa ukundi.
Abantu benshi ntibajya bumva ikintu na kimwe. Nk’uko CDC ibivuga, umuntu umwe kuri batanu agira umuriro, umutwe, kubabara umubiri, kuruka no gucibwamo. Ibimenyetso bikunze kugaragara nyuma y’iminsi 3-14 umuntu arumwe.
Umuntu umwe kuri 150 banduye virusi ya West Nile ahura n’ibibazo bikomeye, harimo n’urupfu. Umuntu wese ashobora kurwara bikomeye, ariko Staples yavuze ko abantu barengeje imyaka 60 n’abafite ibibazo by’ubuzima biri mu kaga gakomeye.
Nyuma y'imyaka itanu asanzwe arwaye West Nile, Vandenberg yongeye kugarura ubushobozi bwe bwinshi binyuze mu buvuzi bw'umubiri buhanitse. Ariko, amaguru ye yakomeje kubura ibinya, bituma yishingikiriza ku nkoni.
Ubwo Vandenberg yagwaga muri icyo gitondo muri Nzeri 2018, yari agiye gushyingura inshuti ye yari yapfuye azize indwara za virusi ya West Nile.
Yagize ati: “Iyi ndwara ishobora kuba ikomeye cyane kandi abantu bagomba kubimenya. Ishobora guhindura ubuzima bwawe.”
Nubwo kurwanya imiti yica udukoko bishobora kwiyongera, itsinda rya Connolly ryasanze imiti isanzwe yica udukoko abantu bakoresha hanze igifite akamaro. Nk’uko Ikigo gishinzwe kurwanya no gukumira indwara (CDC) kibitangaza, ni byiza gukoresha imiti yica udukoko irimo ibintu nka DEET na picaridin.
