Dengue activity across the Americas has fallen sharply this year, and the size of the drop is worth stating plainly because it runs against the impression most people have of the disease.
Through epidemiological week 29, countries in the region reported 1,470,237 suspected dengue cases, a cumulative incidence of 142 per 100,000 people. That is a decrease of 60 percent compared with the same period in 2025 and 66 percent below the average of the last five years, according to the Pan American Health Organization.
