    About

    This study describes the rising threat of dengue and Zika viruses due to climate change. It predicts increased transmission in Brazilian cities like Manaus, Recife, Rio de Janeiro, and São Paulo by 2050. Warmer temperatures extend mosquito breeding seasons, leading to more outbreaks even in cooler regions. The loss of biodiversity from deforestation worsens the situation as mosquitoes thrive without natural predators. Experts suggest replanting rainforests in urban areas to combat mosquito populations and emphasize the need for better disease surveillance and preparedness as climate change continues to impact public health globally.
