The Pan American Health Organization (PAHO) is urging countries of Central America, Mexico and the Caribbean to strengthen preventive measures against dengue fever as it notes an increase in cases in the southern hemisphere and the beginning of the season of increased transmission in the northern hemisphere.
Dengue is a mosquito-borne viral disease that, in most cases, has no symptoms. However, when symptoms do occur, they usually include high fever, headache, body aches, nausea and rash.
In a recent epidemiological alert, PAHO emphasized the importance of strengthening surveillance, diagnosis and vector control actions, as well as preparing health services for the proper management of patients.
As of mid-May 2024, the Americas region has reported more than 8.1 million suspected cases of dengue, marking a 3.3-fold increase compared to the same period last year.
The countries with the highest number of reported cases are Brazil, Argentina, Paraguay, Peru, Colombia and Mexico. More than 3,600 dengue-related deaths have been reported throughout the region.
Countries and territories in the Caribbean have reported over 21,000 cases, representing a 5.7-fold increase compared to the corresponding period last year.
