Observatory estimates 11,235 dengue cases in Cuba in 2026
The estimate, updated through October 4, is 9.2 times the country's historical average over the past five years; these are not official Public Health Ministry figures.
Cuba had an estimated 11,235 dengue cases so far in 2026, 9.2 times the historical average over the past five years, according to the Global Dengue Observatory at the London School of Hygiene and Tropical Medicine, based on data updated through October 4.
Monthly estimates were about 2,173 infections in July, 3,214 in August and 4,102 in September, the highest monthly figure of the year up to that point. The source notes that these estimates are not official figures from the Ministry of Public Health, which had not published updated national epidemiological bulletins for those months.
By mid-September, the cumulative estimate was around 7,133 cases, or 7.4 times the expected level, according to the Observatory. October is usually the month of greatest transmission on the island, and the peak may not yet have been reached.
