Isibulala-zinambuzane-Amanethi aphathwayo (ITNs) abe yisisekelo semizamo yokuvimbela umalaleveva kule minyaka engamashumi amabili edlule, futhi ukusetshenziswa kwawo kabanzi kuye kwadlala indima enkulu ekuvimbeleni lesi sifo nasekusindiseni ukuphila. Kusukela ngo-2000, imizamo yokulawula umalaleveva emhlabeni wonke, kuhlanganise nemikhankaso ye-ITN, ivimbele izehlakalo ezingaphezu kwezigidi eziyizinkulungwane ezimbili zikamalaleveva kanye nokufa cishe kwezigidi eziyi-13.
Naphezu kwenqubekelaphambili ethile, omiyane abasakaza umalaleveva ezindaweni eziningi baye bamelana nezibulala-zinambuzane ezivame ukusetshenziswa emanethini afakwe izibulala-zinambuzane, ikakhulukazi ama-pyrethroids, okunciphisa ukusebenza kwawo kanye nokubukela phansi inqubekelaphambili ekuvimbeleni umalaleveva. Lolu songo olukhulayo luye lwashukumisela abacwaningi ukuba basheshise ukwakhiwa kwamanetha amasha anikeza isivikelo esihlala isikhathi eside kumalaleveva.
Ngo-2017, i-WHO yancoma inethi yokuqala efakwe isibulala-zinambuzane eklanyelwe ukuthi isebenze kangcono ngokumelene nomiyane abamelana ne-pyrethroid. Nakuba lesi kwakuyisinyathelo esibalulekile esiya phambili, kudingeka olunye uguquko olusha ukuze kwakhiwe amanetha asebenza kabili alashwe izibulala-zinambuzane, kuhlolwe ukusebenza kwawo ngokumelene nomiyane abamelana nezibulala-zinambuzane kanye nomthelela wabo ekusakazeni umalaleveva, nokuhlola ukusebenza kahle kwawo kwezindleko.
Ishicilelwe ngaphambi koSuku Lomhlaba Luka-Malaleveva lwango-2025, lesi sithombe sigqamisa ucwaningo, ukuthuthukiswa kanye nokusatshalaliswa kwamanethi agaywa ngezibulala-zinambuzane ezimbili (ama-DINETs) - umphumela weminyaka yokubambisana phakathi kwamazwe, imiphakathi, abakhiqizi, abaxhasi kanye nohlu lwabalingani bomhlaba wonke, isifunda kanye nozwelonke.
Ngo-2018, i-Unitaid kanye ne-Global Fund yethula iphrojekthi entsha ye-Nets, eholwa yi-Coalition for Innovative Vector Control ngokubambisana eduze nezinhlelo zikazwelonke zikamalaleveva kanye nabanye ababambisene nabo, okuhlanganisa ne-US President's Malaria Initiative, i-Bill & Melinda Gates Foundation kanye ne-MedAccess, ukusekela ukukhiqizwa kobufakazi kanye namaphrojekthi okuhlola ukusheshisa ukuguqulelwa kwe-Afrika engaphansi kweSahara. ukumelana ne-pyrethroid.
Amanethiwekhi aqala ukufakwa eBurkina Faso ngo-2019, futhi eminyakeni eyalandela eBenin, Mozambique, Rwanda nase-United Republic of Tanzania ukuhlola ukuthi amanethiwekhi asebenza kanjani ezimeni ezahlukene.
Ekupheleni konyaka wezi-2022, iphrojekthi yeNew Mosquito Nets, ngokubambisana neGlobal Fund kanye ne-US President’s Initiative’s Malaria Initiative, izobe isifake amanethi omiyane angaphezu kwezigidi ezingama-56 emazweni ayi-17 e-Afrika eseningizimu ye-Sahara lapho kubhalwe phansi ukumelana nezibulala-zinambuzane.
Izivivinyo zemitholampilo kanye nezifundo zokuhlola zibonise ukuthi amanetha aqukethe izibulala-zinambuzane ezisebenza kabili athuthukisa amazinga okulawula umalaleveva ngo-20–50% uma kuqhathaniswa namanethi ajwayelekile aqukethe i-pyrethrins kuphela. Ukwengeza, izivivinyo zemitholampilo e-United Republic of Tanzania nase-Benin zibonise ukuthi amanetha aqukethe i-pyrethrins ne-chlorfenapyr anciphisa kakhulu izinga lokutheleleka umalaleveva ezinganeni ezisukela ezinyangeni eziyisi-6 kuye kweyi-10.
Ukukhuphula ukuthunyelwa nokuqapha kwamanethi omiyane esizukulwaneni esilandelayo, imigomo kanye nobunye ubuchwepheshe obusha kuzodinga ukutshalwa kwezimali okuqhubekayo ezinhlelweni zokulawula umalaleveva kanye nokuqeda, okuhlanganisa nokuqinisekisa ukugcwaliswa kabusha kwe-Global Fund kanye ne-Gavi Vaccine Alliance.
Ngaphezu kwamanetha amasha ombhede, abacwaningi benza uchungechunge lwamathuluzi amasha okulawula ama-vector, njengezinto ezixosha emkhathini, izinti ezibulalayo zasekhaya (amashubhu wezinduku zamakhethini), nomiyane abakhiwe ngofuzo.
