These figures show that there has been a peak of the outbreak during the last weeks that has triggered the need for a response.

The Ministry of Public Health has reported a total of 8,855 cases of dengue as of Epidemiological Week (EW) 33 (11 to 17 August), there is an increase that looks quite significant compared to the number of cases reported for the dengue epidemic in 2018 (711 cases as of EW 33).

Four dengue serotypes are present in the Dominican Republic. According to laboratories, the predominant serotypes identified during the current outbreak are D1 and D3, and the presence of all four serotypes increases the risk of severe cases.

The highest incidence rate is seen in the provinces of Barahona (485.4) and Independencia (457.6), and Santo Domingo reports the highest number of cases (2614 cases) due to its large population.
