Dengue worldwide

Latin America is the region with the highest number of reported dengue fever infections in the world. In 2023, more than 6.5 million cases and 7,300 deaths were reported globally. As of that year, nearly half of the population was estimated to be at risk of a dengue infection, and around 100 countries were considered endemic to the disease.

Regional differences

Dengue is cyclical and seasonal, meaning that the time of the year in which cases peak varies from country to country, and that larger outbreaks take place every certain number of years. In Latin America, Brazil, for instance, sees its highest number of cases usually reported between March and May, while in Mexico dengue season takes places between June and October.
