"Dengue Outbreaks Surge Worldwide: Climate Change and Global Circulation of Virus Raise Concerns"
The global incidence of dengue has significantly increased over the past two decades, with a ten-fold surge in reported cases from 2000 to 2019. In 2023, there has been an upsurge in dengue cases globally, with over five million cases and more than 5,000 deaths reported in over 80 countries. Factors contributing to the spread of the epidemic include changing distribution of the vectors, climate change, fragile health systems, and high population movements. Weaknesses in surveillance systems and delayed reporting have led to increased severe dengue outcomes. The World Health Organization (WHO) has assessed the risk to be high globally and is implementing a coordinated response to support affected countries.
