E ai ki te Pūrongo Malaria o te Ao 2025 a te Whakahaere Hauora o te Ao, kua piki ake ngā keehi malaria i Amerika mā te 15.7% i waenga i te tau 2015 me te tau 2024.
He mate toto te malaria e tukuna ana e ngā waeroa e mau ana i te pirinoa Plasmodium. Ahakoa ngā mahi whakahaere waeroa, kei te horapa tonu te malaria i ētahi wāhanga o Amerika ki te Tonga, Āhia, me Āwherika. I roto i tētahi pepa o Poutū-te-rangi i roto i te Science, i tirotirohia e Jacob Tennison mā ngā hoa mahi te ira o te taupori o Anopheles (Nyssorhynchus) darlingi, te kawe malaria matua i Amerika ki te Tonga. I kitea e ngā kairangahau kei te whanake haere te ātete o Anopheles darlingi ki ngā patu pepeke.
I raupapahia e Tennessen me āna hoa mahi ngā ira o ngā waeroa 1,094 mai i ngā whenua e ono (Brazil, Colombia, French Guiana, Guyana, Peru, me Venezuela). I kitea e rātou ngā rerekētanga ira e puta pinepine ana i roto i ngā taupori tata, inā koa i roto i te matapihi 150-kb e kapi ana i ngā ira e ono e whakamārama ana i te cytochrome P450. Ko ngā whakarerekētanga ira i roto i ngā ira P450 e hono ana ki te ātete ki ngā patu pepeke pyrethroid, e kitea ana i roto i te Anopheles funestus me te Anopheles gambiae i Awherika ki te tonga o te Sahara.
Wheakohia te māramatanga tino pai mā te tūāpapa kotahi e whakakotahi ana i ngā raraunga ahurei, te mātauranga horihori, me te mōhiotanga tohunga.
I tautuhia anō e ngā kaituhi tēnei whakarerekētanga tino whiriwhiri hei momo whakarerekētanga i roto i te ira CYP6AA1, e tohu ana tētahi ira i te threonine i te tūranga 283, ā, ko tētahi e tohu ana i te lysine. Hei whakamātautau mēnā ka ātete tēnei momo whakarerekētanga ki ngā pepeke i roto i ngā waeroa, i hopukina e ngā kairangahau te 16 ngā Anopheles darlingi mohoao, ā, i rongoatia ki te deltamethrin. I whakaatuhia e ngā hua he roa ake te ora o ngā waeroa e mau ana i te momo whakarerekētanga threonine-lysine i ērā he homozygous mō te threonine, he homozygous rānei mō te lysine. Nō reira, kei te whiriwhiria te taupori Anopheles darlingi mō ngā whakarerekētanga e whakarei ake ana i tōna ātete ki te deltamethrin.
E ai ki te "World Malaria Report 2025" a te World Health Organization (WHO), kua piki ake ngā take malaria i ngā whenua o Amerika mā te 15.7% i waenga i te tau 2015 me te tau 2024, ā, ko Venezuela, Brazil, me Colombia te 75% o ēnei take. E matapaetia ana e ngā tohunga mate urutā i GlobalData, tae noa ki te tau 2026, neke atu i te 160,000 ngā take malaria kua whakamanahia i Brazil, me te neke atu i te 1.6 miriona ngā take hou.
Ko te mea nui ki te whakakore i te malaria kei roto i te whakahaere i ngā pepeke kawe mate. Kua whanake te ātete o ngā waeroa o te momo Anopheles africanus ki ngā patu pepeke pyrethroid, ā, te āhua nei kei te whanake motuhake tēnei ātete i roto i ngā waeroa o te momo Anopheles dulcis. I te mea kei te haere tonu te pēhanga whanaketanga ki te akiaki i te ātete ki ngā waeroa, ka nui haere te uaua o te whakahaere i te taupori waeroa, ā, ka nui haere te uaua o te whakakore i te malaria. Nō reira, me matua hoatu ki ētahi atu tikanga whakahaere kawe mate me ngā mate.
