Brazil faces severe dengue fever outbreak, exacerbated by climate change

Brazil is facing a severe dengue fever outbreak, with an expected 4.2 million cases this year, surpassing the 4.1 million cases in the entire Americas last year. Factors such as El Niño and climate change have exacerbated the issue. Record heat and above-average rainfall have increased mosquito breeding sites. Brazil's health minister, Nísia Trindade, highlighted the widespread impact, even in regions with historically few cases.
