Surging cases of yellow fever and dengue in South America highlight the growing assault on people’s health from the climate crisis, with infectious diseases spread by mosquitoes and deadly heat also now pushing into temperate regions such as Europe, experts have warned at the Cop30 climate summit.
There have been 356 cases of yellow fever in South America and 152 deaths so far this year, largely in the Amazon region, according to Pan American Health Organization figures. Apart from a large spike in 2017 and 2018, this is the largest number of yellow fever cases for any year in the continent, bar one, since 1960.
