Cuba faces a severe dengue season in 2026, with over 7,133 accumulated cases, 7.4 times the expected level. September recorded 3,214 cases, a 32% increase from August.
The situation is exacerbated by the deterioration of vector surveillance, a shortage of medical supplies such as serums and reagents, and an overloaded hospital system. Severe cases and deaths, particularly among children, are reported in several provinces, including Guantánamo, Sancti Spíritus, and Las Tunas. The lack of timely diagnosis and adequate treatment, coupled with environmental conditions conducive to the proliferation of the Aedes aegypti mosquito, contribute to the crisis. The country does not update official dengue figures on public databases, hindering monitoring and response.
