Summary:

The incidence of dengue has grown dramatically worldwide in recent decades, with the number of cases reported to WHO increasing from 505,430 in 2000 to 14.6 million in 2024. The disease is now endemic in more than 100 countries. The Americas, South-East Asia, and the Western Pacific regions are the most seriously affected, with Asia accounting for approximately 70% of the global disease burden. Dengue is also spreading to previously non-endemic regions such as Europe, raising the threat of explosive outbreaks. 

 Cases reported among travellers have also increased, confirming dengue as the most frequently diagnosed arboviral infection in post-travel settings. 

  Vaccines represent one of the primary tools for dengue control and have recently been introduced into national immunization programs in many low- and middle-income countries (LMICs).
