00:00Malaria rates fell from 79 to 59 cases per 1,000 people at risk between 2000 and 2015.
00:07But Dengue's rise reveals why warming alone cannot explain the gap.
00:12A review in Science Advances examined existing research on these contrasting trends.
00:17It found that climate shapes potential spread, while social conditions helped determine actual risk.
00:23So malaria benefited from better health care, treatments, bed nets, and indoor spraying.
00:27Meanwhile, growing cities provide containers where mosquitoes that spread Dengue can breed.
00:32But cities often reduce natural habitats favored by mosquitoes that spread malaria.
00:37And Dengue mosquitoes typically bite during daylight, making bed nets less effective.
00:42Meanwhile, Dengue has fewer established controls, with emerging tools' widespread impact limited or uncertain.
00:49Yet malaria's gains remain fragile, with rates rising to 64 in 2024.
00:54So the divide reflects more than heat.
00:56Cities and disease control matter, too.
