Ukuthuthukisa izindlela ezithembekile nezijwayelekile zokuhlola ukuthambekela kwezinambuzane eziwumiyane kuma-insecticide kubalulekile ekuqondeni ukusebenza kahle kwezithako ezisebenzayo noma ukwakheka. Izindlela zokuhlola ukuthambekela kwezinambuzane eziwumiyane ekuthinteni ama-insecticide noma imikhiqizo (njengaleyo ekhuthazwa ezinhlelweni zezempilo zomphakathi) zisungulwe kahle futhi zijwayelekile. Kodwa-ke, izindlela zokuhlola ama-insecticide aguquguqukayo noma a-aerosol asetshenziswa emikhiqizweni yasekhaya kunzima ukuzisebenzisa ngempumelelo. Ngokusekelwe ezincomweni ze-World Health Organisation zama-insecticide asekhaya, sithuthukise indlela ejwayelekile nephezulu yokuhlola imikhiqizo ye-aerosol sisebenzisa omiyane abavalelwe kanye nendlela ephumelelayo yokubulala amagciwane eyenziwa ekamelweni lokuhlola le-Peet-Grady (igumbi lokuhlola le-PG). Siqinisekisile ukusebenza kahle kwale ndlela entsha sisebenzisa inqwaba yomiyane abalwa nezinambuzane nabasengozini yokubulala amagciwane. Isici esisha sale ndlela ukufakwa kwegumbi eliqondiswe emakhejini omiyane, okuvumela ukuhlolwa kwesilinganiso kwesikhathi sangempela samazinga okubulala omiyane ngemva kokuchayeka kuma-insecticide. Ukubulala amagciwane nge-swab kususa ngempumelelo uwoyela we-aerosol osele oqukethe i-pyrethroid ebusweni begumbi lokuhlola, ngamazinga okufa angaphansi kuka-2% komiyane abasengozini abahlolwe ngqo ebusweni begumbi. Akukho ukungafani kwendawo emazingeni okubulala noma okufa phakathi komiyane abavalelwe ekhejini okwabonwa ekamelweni le-PG. Indlela yethu yamakheji amabili inikeza amandla okudlula izikhathi eziyisishiyagalombili kunendlela yokundiza mahhala, okuvumela ukuhlolwa ngasikhathi sinye kwezinhlobo ezahlukene zomiyane kanye nokuhlukanisa okuphumelelayo phakathi kwezinhlobo zomiyane ezisengozini kanye nezingamelani ezihlolwe ngasikhathi sinye.
Kuze kube manje, izibulala-zinambuzane ezisebenzisa i-aerosol zisetshenziswa kakhulu ekhaya ukuze zivikeleke, futhi zingasetshenziswa kancane ezinhlelweni zezempilo zomphakathi. Kodwa-ke, izifundo zakamuva zibonise ukusetshenziswa kwezibulala-zinambuzane zasekhaya okusabalele ezindaweni lapho izifo ezithwalwa yizinambuzane zivame khona. Kungakhathaliseki ukuthi isisusa siwukuxosha omiyane noma ukuvimbela izifo, kunesidingo esiphuthumayo sezindlela ezijwayelekile nezilula zokuhlola inqwaba yomiyane abatholakala emvelweni ukuze babone ukuthi basengozini kangakanani ezibulala-zinambuzane zasekhaya. Lokhu kubalulekile ekubikezeleni ukusebenza kahle kwezibulala-zinambuzane ezilwa nezinambuzane ezithwala izinambuzane endaweni kanye nokuqonda ukuthi ukusetshenziswa kwezibulala-zinambuzane zasekhaya kuthonya kanjani ukukhethwa kokuziphendukela kwemvelo kokumelana nezibulala-zinambuzane.
Indlela Engeziwe 1 inikeza imiyalelo enemininingwane yesinyathelo ngesinyathelo yokwenza uhlelo lwethu lokuhlola izinambuzane nge-aerosol.
Nakuba iziqondiso ze-WHO zincoma ukusetshenziswa kwama-nebulizer azenzakalelayo, azinikezi imininingwane ethile yobuchwepheshe. Ukusetshenziswa kwama-nebulizer azenzakalelayo kubalulekile, njengoba i-nebulization ngesandla ekamelweni le-propylene glycol ayidingi nje kuphela umsebenzi kodwa futhi ingabangela ukungahambisani kwendawo kanye nokwehluka kwesikhathi se-nebulization.
Igumbi lokusabela kumele lihlanzwe ngokubulala amagciwane ngemva kokuhlolwa ngakunye, kodwa indlela yokuhlanza yangaphakathi enconywe ku-WHO Guideline ihilela ukufaka amanzi avela epayipini. Emsebenzini wethu wansuku zonke, le ndlela iyisinyathelo esidinga kakhulu umsebenzi ekusebenzeni kwemishini yokuhlaziya izinto eziphilayo, ngakho-ke sakha futhi sahlola inqubo yokubulala amagciwane esekelwe ku-swab.
Izingxenye ezisuswayo zefeni ziphathwa njengoba kuchaziwe ngenhla, futhi ama-blade nohlaka lwefeni kuhlanzwa ngesiponji esicwiliswe kusisombululo esingu-5% se-Decon 90.
Ngokusekelwe ebuhlotsheni phakathi kwesikhathi sokufafaza kanye nesilinganiso sokulethwa komkhiqizo, i-aerosol dispenser yethu iphinde yabonisa ukunemba okuhle ekulawuleni isilinganiso somthamo we-aerosol, okungenani ngaphezu kwebanga elivivinyiwe lezikhathi ezingu-1 kuya kwezingu-4. Njengoba kuboniswe ku-Fig. 3b, lesi sici sibaluleke kakhulu ekuchazeni ubudlelwano bomthamo nempendulo yezindlela ezintsha ze-aerosol noma ekunqumeni umthamo wokuhlonza wokuthola ukumelana nezinambuzane.
Sibonisa ukuthi inqubo yethu ebuyekeziwe yokuhlola izibulala-zinambuzane zasekhaya, ukusebenzisa ukubulala amagciwane nge-swab, amakheji amabili, izifutho ezilawulwa kude, kanye nokuqoshwa kwe-biometric kusuka kumakhamera esenzo, kuyindlela ephumelela kakhulu futhi engenzeka kuneyamanje.I-WHOizincomo. Indlela yokubulala amagciwane nge-swab, edinga imizuzu engama-20 kuphela, isindisa kakhulu isikhathi uma kuqhathaniswa nenqubo ekhona (evame ukudinga ihora elilodwa ngegumbi lokuhlola). Iphinde inciphise isikhathi opharetha abasichitha begqoke imishini yokuzivikela ephelele (isb., izigqoko zokuphefumula kanye nezingubo zokusebenza ezingashintshi). Ngaphezu kwalokho, le ndlela ikhiqiza uketshezi olungcolile kanye nezingubo zokwelashwa okuncane kunokuhlanza ngokuphelele igumbi lokuhlola, ngaleyo ndlela inciphise amathuba okungcoliswa kwegumbi elihlala igumbi lokuhlola. Indlela yokubulala amagciwane nge-swab ifaneleka futhi ekubulaleni amagumbi okuhlola angahlali isikhathi eside adingaokuncaneukubeka ifenisha ezindaweni ezahlukene zekamelo.
Inkinga ebalulekile ehlolwe kulolu cwaningo kanye nezinye ukulinganisa imithamo yokuchayeka kwemithi yokubulala izinambuzane esetshenziswa endaweni ezungezile kuzo zonke izindlela zokuhlola ezahlukene. Njengoba kuboniswe kuMfanekiso 2b, naphezu kwesikhathi sokufafaza esinqunyiwe, ivolumu yokufafaza yahlukahluka kuzo zonke izinhlobo zamathini e-aerosol, okungenzeka ibonise umehluko ezinqubweni zokukhiqiza (isb., ingcindezi yangaphakathi, ukusetshenziswa kwe-propellant, isakhiwo se-nozzle, njll.). Ngaphezu kwalokho, ukuntuleka kwamanje kwamadivayisi okufafaza akude atholakalayo kwezentengiselwano anokuguquguquka okudingekayo esikhathini sokufafaza kunciphisa ukusetshenziswa kwawo ekuhloleni ubudlelwano bokuphendula umthamo nokulawula omiyane. Ukufafaza ngesandla ngama-hatch okuhlola noma ama-hatch okufinyelela (uma ekhona) kungaholela ekuhlukeni kwemithamo yokuchayeka. Eqinisweni, imiphumela yethu iqokomisa isidingo nokubaluleka kokunciphisa le mithombo yokuguquguquka. Kubantu be-Aedes aegypti abamelana nalesi simo, sibone ukuhlangana phakathi kwemithamo ye-aerosol kanye nokunqunywa kokugcina kokuzwela noma ukumelana (Isithombe 3b). Okufanelekile, imithamo ye-aerosol kufanele ilinganiswe ngamagremu ento e-aerosol kunokuba ibe sesikhathini sokufafaza ukuze kube lula ukuqhathanisa phakathi kwezifundo ezahlukene.
I-RCAD inikeza indlela ehlukile yocwaningo lwesikhathi esizayo olunciphisa umthelela wokushintshashintsha kwenqubo. Nakuba sithole ukuthi ukulinganisa izifutho ze-aerosol akunakwenzeka, sibonise ukuthi isisindo se-aerosol esilethwa ngamathini e-aerosol ahlukene singalinganiswa ngokuphindaphindiwe ngokulinganisa ubude besifutho (Izithombe 2b, 3a). Ukulinganisa okunjalo kokuhlushwa kwe-aerosol kunoma yiliphi igumbi lokuhlola kubalulekile ekuthuthukiseni ukuphindaphinda kwemiphumela.
Ngokusekelwe kokuhlangenwe nakho kwethu kanye nokwamanye amaqembu ocwaningo, izincomo eziqukethwe ku-Guideline yamanje mayelana nokusetshenziswa kwezindlela zokuthola i-aerosol zokuhlola omiyane abandiza ngokukhululeka zibeka izinselele ezinkulu zezokuthutha ezifundweni zelebhu kanye nezifundo zasensimini. Isibonelo, izindlela zokuthola omiyane abandiza ngokukhululeka zinezinga eliphansi kakhulu lokuphumelela (kufaka phakathi ukubanjwa kabusha komiyane abasinda ngokukhululeka) futhi zihlushwa imikhawulo eminingi yobuchwepheshe, njengobunzima ekunqumeni amazinga okubulala ngesikhathi sangempela.
Nakuba ukuhlolwa kwethu okuqinisekisiwe kwe-double-cage kulungisa inkinga yokulinganiselwa kokugeleza kwamanzi futhi kuyindlela engenzeka yokuhlola ukuthambekela komiyane ezidakamizweni ze-aerosol, kufanele kuqashelwe ukuthi amazinga okufa komiyane baseCayman Islands ayephansi kakhulu ekuhlolweni kwe-cage kunasekuhlolweni kokundiza mahhala (Isithombe 5c, Ithebula 1). Lo mehluko ungabonisa ukwehla komthamo we-insecticide ngaphakathi kwe-cage, njengoba amaconsi ambalwa e-aerosol angena ku-mesh futhi angene e-cage. Izifundo zesikhathi esizayo zingasebenzisa izindwangu ezinkulu ze-mesh kanye nemiklamo ye-cage enezinga eliphezulu lokugeleza komoya kwabalandeli (isb., imiklamo ye-cylindrical) ukuqinisekisa imiphumela etholwe ngezindlela ezahlukene zokuhlola.
