The increase of dengue and chikungunya ‘s incidences are major public health problem in the Region of the Americas. Dengue accounts for the largest number of cases in the Region, with epidemics occurring every three to five years. Although dengue and chikungunya are endemic in most countries of Central America, South America, and the Caribbean, in the current summer season, increased transmission and expansion of chikungunya cases have been observed beyond historical areas of transmission. Furthermore, 2023 is showing intense dengue transmission.
