The trend remains above the epidemic threshold and exceeds the cases reported in 2023. Additionally, the hurricane season has begun, marking the start of the rainy season, which has historically been associated with an increase in dengue cases.
The five municipalities with the highest incidence rates – cases per 100,000 inhabitants – so far this year are: Rincón (809.90), Canóvanas (196.05), Aguada (191.42), Orocovis (163.29), and San Juan (130.90).

The age group of 40 to 59 years accumulates the highest number of cases, with 370 (19.01%), followed by the group of 10 to 14 years, with 300 (15.42%), and the group of 15 to 19 years, with 291 (14.95%). Additionally, up to week 27 – covering from July 1 to 7 – a total of 1,090 (56.01%) hospitalized cases had been reported. Of the total cases with a positive laboratory test for dengue, 116 (5.96%) meet the World Health Organization’s 2009 definition of severe (or severe) dengue.
The most recent report also shows that serotype 3 continues to dominate during this epidemic, with 785 confirmed cases (48.46%), while 438 (27.04%) belong to serotype 1 and 397 (24.51%) to serotype 2.
