Guyana is facing its largest dengue epidemic in around twenty years: it began in mid-2023 and has accelerated since the beginning of January 2024 with 800 new cases declared on average per week, according to the health authorities. This virus transmitted by Aedes mosquitoes, against which no vaccine is recommended by the High Authority for Health (HAS), can cause hemorrhages or shock syndromes in the most serious cases.

According to Public Health France, 5,800 confirmed cases of dengue fever have been recorded in the Amazon department of 300,000 inhabitants since the start of 2023, including 2,996 already in 2024. In tropical and intertropical zones, such as Guyana , epidemics recur every three to five years and generally last 12 to 18 months. Viral waves are more or less intense.

A monitoring unit associating State services and the Territorial Collectivity of Guyana (CTG) was activated on February 6 with a view to taking measures “to curb this dynamic as much as possible”announced prefect Antoine Poussier.
