Guyana is facing its largest dengue epidemic in 20 years. The epidemic has accelerated since the beginning of January with 800 new cases on average per week.

The virus transmitted by Aedes mosquitoes can cause hemorrhages or shock syndromes in the most serious cases. In tropical and intertropical areas, such as Guyana, epidemics return every three to five years and generally last 12 to 18 months. According to Public Health France, 5,800 confirmed cases of Dengue fever have been recorded in the Amazonian department since the start of 2023, including 2,996 already in 2024.
