Ukuphuhlisa iindlela ezithembekileyo nezisemgangathweni zokuvavanya ukuba iingcongconi zisengozini kangakanani kwizinambuzane kubalulekile ekuqondeni ukusebenza kwezithako okanye iindlela ezintsha ezisebenzayo. Iindlela zokuvavanya ukuba iingcongconi zisengozini kangakanani na ukuba ziqhagamshelane nezinambuzane okanye iimveliso (ezifana nezo zikhuthazwa kwiinkqubo zempilo yoluntu) zimiselwe kakuhle kwaye zisemgangathweni. Nangona kunjalo, iindlela zokuvavanya izinambuzane eziguquguqukayo okanye ezisebenzisa i-aerosol ezisetyenziswa kwiimveliso zasekhaya kunzima ukuzisebenzisa ngokufanelekileyo. Ngokusekelwe kwiingcebiso ze-World Health Organisation malunga nezinambuzane zasekhaya, siphuhlise indlela esemgangathweni nephezulu yokuvavanya iimveliso ze-aerosol sisebenzisa iingcongconi ezivalelwe kwiikheyiji kunye nendlela esebenzayo yokubulala iintsholongwane eqhutywa kwigumbi lovavanyo lasePeet-Grady (igumbi lovavanyo lePG). Siqinisekisile ukusebenza kwale ndlela intsha sisebenzisa amaqela eengcongconi ze-Aedes kunye ne-Anopheles ezinganyangekiyo kwizinambuzane nezisengozini. Uphawu olutsha lwale ndlela kukubandakanywa kwegumbi elijoliswe kwiikheyiji zeengcongconi, okuvumela uvavanyo lwangempela lobungakanani bamazinga okubulawa kweengcongconi emva kokuvezwa kwizinambuzane. Ukubulala iintsholongwane nge-swab kususa ngokufanelekileyo ioyile ye-aerosol eseleyo equlethe i-pyrethroid kumphezulu wegumbi lovavanyo, kunye namazinga okufa angaphantsi kwe-2% kwiingcongconi ezisengozini ezivavanywe ngqo kumphezulu wegumbi. Akukho mahluko phakathi kweendawo ezibulalayo okanye ezifayo phakathi kweengcongconi ezivalelweyo abonwanga kwigumbi le-PG. Indlela yethu yokusebenzisa ii-dual-cage inika amandla okufikelela aphezulu ngokuphindwe kasibhozo kunendlela yokubhabha ngokukhululekileyo, nto leyo evumela uvavanyo lwangaxeshanye lweentlobo ezahlukeneyo zeengcongconi kunye nokwahlulahlula okusebenzayo phakathi kweencongconi ezisengozini nezinganyangekiyo ezivavanyiwe ngaxeshanye.
Ukuza kuthi ga ngoku, izibulali-zinambuzane ezisebenzisa i-aerosol zisetyenziswa kakhulu emakhaya ukuzikhusela, kwaye zingasetyenziswa kakhulu kwiinkqubo zempilo yoluntu. Nangona kunjalo, uphando lwakutshanje lubonise ukusetyenziswa kwezibulali-zinambuzane zasekhaya ngokubanzi kwiindawo apho izifo ezithwalwa zizinambuzane zixhaphake khona. Nokuba injongo kukugxotha iingcongconi okanye kukuthintela izifo, kukho imfuneko engxamisekileyo yeendlela ezisemgangathweni nezilula zokuhlola inani leengcongconi ezihlala apho ukuze zifumaneke lula kwiintsholongwane zasekhaya. Oku kubalulekile ekuqikeleleni ukusebenza kwezibulali-zinambuzane ngokuchasene nezibulali-zinambuzane zasekuhlaleni kunye nokuqonda indlela ukusetyenziswa kwezibulali-zinambuzane zasekhaya okuphembelela ngayo ukhetho lokuchasana nezibulali-zinambuzane.
Indlela Eyongezelelweyo 1 inika imiyalelo eneenkcukacha yenyathelo ngenyathelo yokwenza inkqubo yethu yokuvavanya izinambuzane nge-aerosol.
Nangona izikhokelo ze-WHO zicebisa ukusetyenziswa kwee-nebulizers ezizenzekelayo, aziboneleli ngeenkcukacha zobugcisa ezithile. Ukusetyenziswa kwee-nebulizers ezizenzekelayo kubalulekile, njengoko i-nebulization ngesandla kwigumbi le-propylene glycol ayifuni nje kuphela umsebenzi kodwa inokubangela ukungangqinelani kwendawo kunye nokutshintsha kwexesha le-nebulization.
Igumbi lokusabela kufuneka lihlanjululwe emva kovavanyo ngalunye, kodwa indlela yokucoca yangaphakathi ecetyiswayo kwi-WHO Guideline ibandakanya ukufaka amanzi kwipayipi. Kumsebenzi wethu wemihla ngemihla, le ndlela yeyona inzima kakhulu ekusebenziseni izixhobo ze-bioanalytical, ngoko ke siphuhlise kwaye savavanya inkqubo yokubulala iintsholongwane esekwe kwi-swab.
Iindawo ezisuswayo zefeni ziphathwa njengoko kuchaziwe apha ngasentla, kwaye iiblade kunye nesakhelo sefeni zicocwa ngesiponji esifakwe kwisisombululo se-5% seDecon 90.
Ngokusekelwe kubudlelwane phakathi kwexesha lokutshiza kunye nesantya sokuhanjiswa kwemveliso, i-aerosol dispenser yethu ikwabonakalise ukuchaneka okuhle ekulawuleni umlinganiselo wedosi ye-aerosol, ubuncinci ngaphezulu koluhlu oluvavanyiweyo lwexesha eli-1 ukuya kweli-4. Njengoko kubonisiwe kuMfanekiso 3b, olu phawu lubaluleke kakhulu ekuchazeni ubudlelwane bedosi nempendulo yefomyula entsha ye-aerosol okanye ekumiseleni idosi yokuchonga yokufumanisa ukumelana nezinambuzane.
Sibonisa ukuba inkqubo yethu ehlaziyiweyo yokuvavanya izibulali-zinambuzane zasekhaya, ukusebenzisa ukubulala iintsholongwane nge-swab, iikheyiji ezimbini, izitshizi ezilawulwa kude, kunye nokurekhoda kwebhayomethri kwiikhamera zesenzo, yindlela esebenzayo nefanelekileyo kuneyangoku.I-WHOiingcebiso. Indlela yokubulala iintsholongwane nge-swab, efuna imizuzu engama-20 kuphela, igcina ixesha kakhulu xa ithelekiswa nenkqubo ekhoyo (edla ngokufuna iyure enye kwigumbi lovavanyo). Ikwanciphisa ixesha elichithwa ngabaqhubi benxibe izixhobo zokuzikhusela ezipheleleyo (umz., izigcina-ntloko zokuphefumla kunye neempahla zokusebenza ezingashukumiyo). Ngaphezu koko, le ndlela ivelisa ulwelo olungcolisekileyo kunye neempahla zonyango ezimbalwa kunokucoca ngokupheleleyo igumbi lovavanyo, ngaloo ndlela inciphisa amathuba okungcoliseka kwigumbi elihlala igumbi lovavanyo. Indlela yokubulala iintsholongwane nge-swab ikwafanelekile ekubulaleni iintsholongwane kumagumbi ovavanyo ahlala ixesha elide afunaubuncinciukubeka ifenitshala kwiindlela ezahlukeneyo zokubeka amagumbi.
Umba ophambili ophononongwe kolu phononongo nakwezinye kukubekwa emgangathweni kweedosi zokuchatshazelwa kwezinambuzane ezisetyenziswa kwindawo engqongileyo kwiindlela ezahlukeneyo zokuvavanya. Njengoko kubonisiwe kuMfanekiso 2b, nangona ixesha lokuchatshazelwa limiselwe, umthamo wokuchatshazelwa wahluka kwiintlobo zeetini ze-aerosol, nto leyo enokubonisa umahluko kwiinkqubo zokuvelisa (umz., uxinzelelo lwangaphakathi, ukusetyenziswa kwepropellant, ulwakhiwo lwe-nozzle, njl.njl.). Ngaphezu koko, ukungabikho kwezixhobo zokuchatshazelwa ezikude ezithengiswayo ezinokuguquguquka okufunekayo kwixesha lokuchatshazelwa kunciphisa ukusetyenziswa kwazo ekuvavanyeni ubudlelwane bedosi nempendulo yokulawula iingcongconi. Ukuchatshazelwa ngesandla ngee-hatch zovavanyo okanye ii-hatch zokufikelela (ukuba ziyafumaneka) kunokukhokelela kwiinguqu kwiidosi zokuchatshazelwa. Enyanisweni, iziphumo zethu zibonisa imfuneko kunye nokubaluleka kokunciphisa le mithombo yokwahluka. Kumaqela e-Aedes aegypti angamelaniyo, sibonile ulwalamano phakathi kwedosi ye-aerosol kunye nokugqitywa kokugqibela kokuchatshazelwa okanye ukuchasana (Umfanekiso 3b). Ngokufanelekileyo, iidosi ze-aerosol kufuneka zilinganiswe kwiigrama zento e-aerosolized endaweni yexesha lokuchatshazelwa ukuze kube lula ukuthelekisa phakathi kwezifundo ezahlukeneyo.
I-RCAD inika indlela eyahlukileyo yophando lwexesha elizayo olunciphisa impembelelo yokwahluka kwenkqubo. Nangona sifumanise ukuba ukumisela imigangatho ye-aerosol sprays akunakwenzeka, sibonise ukuba ubunzima be-aerosol ethunyelwa ngee-aerosol cans ezahlukeneyo bunokuqikelelwa ngokuphindaphinda ngokulinganisa ubude be-spray (Imifanekiso 2b, 3a). Ukumisela imigangatho okunjalo koxinzelelo lwe-aerosol kulo naliphi na igumbi lovavanyo kubalulekile ekuphuculeni ukuphindaphinda kweziphumo.
Ngokusekelwe kumava ethu kunye nakwamanye amaqela ophando, iingcebiso ezikwiSikhokelo sangoku malunga nokusetyenziswa kweendlela zokufumanisa i-aerosol ukuvavanya iingcongconi ezibhabha ngokukhululekileyo zibangela imingeni ebalulekileyo yokulungiselela izifundo zelebhu kunye nezifundo zasentsimini. Umzekelo, iindlela zokufumanisa iingcongconi ezibhabha ngokukhululekileyo zinemveliso ephantsi kakhulu (kubandakanya ukuphinda kubanjwe iingcongconi ezibhabha ngokukhululekileyo) kwaye zinemida emininzi yobuchwephesha, njengobunzima ekumiseleni amazinga okubulala ngexesha langempela.
Nangona uvavanyo lwethu oluqinisekisiweyo lwezikheyiji ezimbini lujongana nomba wokunqongophala kwamanzi kwaye yindlela efanelekileyo yokuhlola ukuba iingcongconi zisengozini kangakanani kwizinambuzane ezibulala izinambuzane ezisebenzisa i-aerosol, kufuneka kuqatshelwe ukuba amazinga okufa kweengcongconi zaseCayman Islands ayephantsi kakhulu kuvavanyo lwezikheyiji kunakwivavanyo lokubhabha ngokukhululekileyo (Umzobo 5c, Itheyibhile 1). Lo mahluko ungabonakalisa ukuncipha kwedosi yezinambuzane ngaphakathi kwezikheyiji, njengoko amathontsi ambalwa e-aerosol engena kwi-mesh aze angene kwikheyiji. Izifundo zexesha elizayo zingasebenzisa amalaphu amakhulu anee-mesh kunye noyilo lwezikheyiji ezinezinga eliphezulu lokuhamba komoya wefeni (umz., uyilo lwesilinda) ukuqinisekisa ngakumbi iziphumo ezifunyenweyo ngeendlela ezahlukeneyo zovavanyo.
