Kupanga njira zodalirika komanso zokhazikika zoyesera kuti udzudzu utha kudwala tizilombo toyambitsa matenda ndikofunikira kwambiri kuti timvetsetse momwe zosakaniza zatsopano kapena mankhwala atsopano amagwirira ntchito. Njira zoyesera kuti udzudzu utha kudwala tizilombo toyambitsa matenda kapena zinthu zina (monga zomwe zimalimbikitsidwa mu mapulogalamu azaumoyo wa anthu onse) zakhazikitsidwa bwino komanso ndizokhazikika. Komabe, njira zoyesera tizilombo toyambitsa matenda tomwe timagwiritsidwa ntchito m'nyumba ndizovuta kugwiritsa ntchito bwino. Kutengera ndi malangizo a World Health Organisation a mankhwala ophera tizilombo m'nyumba, tapanga njira yokhazikika komanso yapamwamba yoyesera zinthu za aerosol pogwiritsa ntchito udzudzu wotsekedwa m'khola komanso njira yothandiza yophera tizilombo yomwe imachitika mu chipinda choyesera cha Peet-Grady (chipinda choyesera cha PG). Tatsimikizira kuti njira yatsopanoyi yagwira ntchito bwino pogwiritsa ntchito udzudzu wa Aedes ndi Anopheles womwe sungathe kudwala komanso wosavuta kudwala. Chinthu chatsopano cha njira iyi ndi kuphatikiza chipinda cholunjika m'makhola a udzudzu, zomwe zimathandiza kuwunika kuchuluka kwa kuphedwa kwa udzudzu nthawi yeniyeni mutakumana ndi tizilombo. Kuphera tizilombo pogwiritsa ntchito swab kumachotsa bwino mafuta otsala a aerosol okhala ndi pyrethroid pamwamba pa chipinda choyesera, ndipo chiwerengero cha imfa cha udzudzu wofooka chomwe chimayesedwa mwachindunji pamwamba pa chipinda. Palibe kusiyana kwa malo pakati pa udzudzu wophedwa kapena womwalira pakati pa udzudzu wosungidwa m'khola komwe kunapezeka mu chipinda cha PG. Njira yathu yokhala ndi zingwe ziwiri imapereka mphamvu yochulukirapo kasanu ndi katatu kuposa njira yowulukira kwaulere, zomwe zimathandiza kuyesa mitundu yosiyanasiyana ya udzudzu nthawi imodzi komanso kusiyanitsa bwino pakati pa udzudzu womwe ungathe kufalikira komanso womwe sungathe kufalikira womwe unayesedwa nthawi imodzi.
Mpaka pano, mankhwala ophera tizilombo toyambitsa matenda a aerosol akhala akugwiritsidwa ntchito kwambiri m'nyumba kuti ateteze munthu payekha, ndipo amagwiritsidwa ntchito pang'ono m'mapulogalamu azaumoyo wa anthu onse. Komabe, kafukufuku waposachedwapa wasonyeza kuti kugwiritsa ntchito mankhwala ophera tizilombo m'nyumba kufalikira m'madera omwe matenda opatsirana ndi tizilombo ndi ofala kwambiri. Kaya cholinga chake ndi kuthamangitsa udzudzu kapena kupewa matenda, pali kufunika kwakukulu kwa njira zokhazikika komanso zosavuta kugwiritsa ntchito pofufuza kuchuluka kwa udzudzu womwe uli m'deralo kuti udziwe ngati uli pachiwopsezo cha mankhwala ophera tizilombo m'nyumba. Izi ndizofunikira kwambiri poneneratu momwe mankhwala ophera tizilombo angathandizire kupha tizilombo m'deralo komanso kumvetsetsa momwe kugwiritsa ntchito mankhwala ophera tizilombo m'nyumba kumakhudzira kusankha kwatsopano kwa mankhwala ophera tizilombo.
Njira Yowonjezera 1 imapereka malangizo atsatanetsatane a sitepe ndi sitepe pochita pulogalamu yathu yoyesera tizilombo toyambitsa matenda pogwiritsa ntchito aerosol.
Ngakhale malangizo a WHO amalimbikitsa kugwiritsa ntchito makina oyeretsera okha, sapereka tsatanetsatane waukadaulo. Kugwiritsa ntchito makina oyeretsera okha ndikofunikira kwambiri, chifukwa makina oyeretsera okha m'chipinda cha propylene glycol sikuti amangofuna ntchito yambiri komanso kungayambitse kusalingana kwa malo ndi kusinthasintha kwa nthawi yoyeretsera.
Chipinda chochitirapo kanthu chiyenera kutsukidwa chikatha kuyezetsa chilichonse, koma njira yoyeretsera mkati yomwe ikulangizidwa mu WHO Guideline imaphatikizapo kugwiritsa ntchito madzi ochokera mu payipi. Pantchito yathu ya tsiku ndi tsiku, njira iyi ndi gawo lofunika kwambiri pakugwiritsa ntchito zida zowunikira zamoyo, kotero tinapanga ndikuyesa njira yoyeretsera pogwiritsa ntchito swab.
Mbali zochotseka za fan zimakonzedwa monga momwe tafotokozera pamwambapa, ndipo masamba ndi chimango cha fan zimatsukidwa ndi siponji yoviikidwa mu yankho la 5% la Decon 90.
Kutengera ubale womwe ulipo pakati pa nthawi yopopera ndi kuchuluka kwa mankhwala operekedwa, chotulutsira mpweya chathu chinawonetsanso kulondola bwino pakulamulira chiŵerengero cha mlingo wa aerosol, osachepera nthawi imodzi mpaka zinayi zomwe zinayesedwa. Monga momwe zasonyezedwera pa Chithunzi 3b, khalidweli ndilofunika kwambiri pofotokoza ubale wa mlingo ndi yankho la mankhwala atsopano a aerosol kapena kudziwa mlingo wodziwira kuti mankhwalawo ndi otani.
Tikuwonetsa kuti njira yathu yosinthidwa yowunikira mankhwala ophera tizilombo a m'nyumba, pogwiritsa ntchito njira yophera tizilombo toyambitsa matenda, ma cage awiri, ma sprayers olamulidwa patali, ndi kujambula kwa biometric kuchokera ku makamera ochitirapo kanthu, ndi njira yothandiza komanso yotheka kuposa njira yamakono.WHOMalangizo. Njira yoyeretsera swab, yomwe imatenga mphindi 20 zokha, imasunga nthawi kwambiri poyerekeza ndi njira yomwe ilipo (yomwe nthawi zambiri imafuna ola limodzi pa chipinda choyesera). Imachepetsanso nthawi yomwe ogwira ntchito amathera atavala zida zonse zodzitetezera (monga zipewa zopumira ndi zovala zogwirira ntchito zoteteza). Kuphatikiza apo, njira iyi imapanga madzi ndi zovala zochepa zodetsedwa poyerekeza ndi kuyeretsa kwathunthu chipinda choyesera, motero imachepetsa kuipitsidwa kwa chipinda chomwe chili ndi chipinda choyesera. Njira yoyeretsera swab ndi yoyeneranso kuipitsidwa m'zipinda zoyesera zomwe sizili zokhazikika zomwe zimafunazochepakuyika mipando m'zipinda zosiyanasiyana.
Nkhani yofunika kwambiri yomwe yafufuzidwa mu kafukufukuyu ndi ena ndi kulinganiza kwa mlingo wa mankhwala ophera tizilombo omwe amagwiritsidwa ntchito m'chilengedwe m'njira zosiyanasiyana zoyesera. Monga momwe zasonyezedwera mu Chithunzi 2b, ngakhale kuti nthawi yothira inali yokhazikika, kuchuluka kwa mankhwala ophera kunasiyana pamitundu yosiyanasiyana ya ma aerosol, zomwe zingayambitse kusiyana kwa njira zopangira (monga kuthamanga kwamkati, kugwiritsa ntchito propellant, kapangidwe ka nozzle, ndi zina zotero). Kuphatikiza apo, kusowa kwa zida zothira mankhwala zomwe zimapezeka m'masitolo zomwe zimakhala ndi kusinthasintha kofunikira pa nthawi yothira mankhwala kumachepetsa kugwiritsa ntchito kwawo poyesa ubale wa mlingo ndi yankho la udzudzu. Kuthira mankhwala pamanja kudzera m'ma hatchi oyesera kapena ma hatchi olowera (ngati alipo) kungayambitse kusiyana kwa mlingo wa mankhwala ophera. Ndipotu, zotsatira zathu zikuwonetsa kufunikira ndi kufunika kochepetsa magwero osiyanasiyana a kusiyanasiyana kumeneku. Kwa anthu a Aedes aegypti olimbana ndi kukana, tawona mgwirizano pakati pa mlingo wa aerosol ndi kutsimikiza komaliza kwa kukana kapena kukana (Chithunzi 3b). Mwachiyembekezo, mlingo wa aerosol uyenera kulinganizidwa mu magalamu a mankhwala ophera tizilombo m'malo mwa nthawi yothira mankhwala kuti zitheke kufananiza pakati pa maphunziro osiyanasiyana.
RCAD imapereka njira ina yofufuzira mtsogolo yomwe imachepetsa zotsatira za kusintha kwa njira. Ngakhale tidapeza kuti kuyika muyezo wa ma spray a aerosol sikungatheke, tawonetsa kuti kuchuluka kwa aerosol komwe kumaperekedwa kudzera m'mabotolo osiyanasiyana a aerosol kumatha kuwerengedwa mobwerezabwereza poyesa kutalika kwa spray (Zithunzi 2b, 3a). Kuyika muyezo koteroko kwa kuchuluka kwa aerosol m'chipinda chilichonse choyesera ndikofunikira kwambiri pakukweza kubwerezabwereza kwa zotsatira.
Kutengera zomwe takumana nazo komanso za magulu ena ofufuza, malingaliro omwe ali mu Guideline yamakono yokhudza kugwiritsa ntchito njira zopezera aerosol poyesa udzudzu wouluka momasuka amabweretsa mavuto akulu pa kafukufuku wa labotale ndi wa semi-field. Mwachitsanzo, njira zopezera udzudzu wouluka momasuka zili ndi mphamvu zochepa (kuphatikizapo kugwiranso ntchito kwa udzudzu wopulumuka momasuka) ndipo zimakumana ndi zolepheretsa zingapo zaukadaulo, monga zovuta kudziwa kuchuluka kwa anthu omwe amaphedwa nthawi yeniyeni.
Ngakhale kuti kuyesa kwathu kovomerezeka kwa zingwe ziwiri kumathetsa vuto la kuchepa kwa madzi ndipo ndi njira yotheka yowunikira momwe udzudzu ungakhudzire mankhwala ophera tizilombo, ziyenera kudziwika kuti kuchuluka kwa imfa za udzudzu wa ku Cayman Islands kunali kotsika kwambiri mu kuyesa kwa zingwe kusiyana ndi kuyesa kopanda ndege (Chithunzi 5c, Gome 1). Kusiyana kumeneku kungasonyeze kuchepa kwa mlingo wa mankhwala ophera tizilombo mkati mwa zingwe, chifukwa madontho ochepa a aerosol amalowa mu ukonde ndikulowa mu khola. Kafukufuku wamtsogolo angagwiritse ntchito nsalu zazikulu za maukonde ndi mapangidwe a zingwe zokhala ndi kuchuluka kwa mpweya wa fan (monga, mapangidwe a cylindrical) kuti atsimikizire zotsatira zomwe zapezeka ndi njira zosiyanasiyana zoyesera.
