Chikungunya fever is spreading faster than dengue in El Slavador

During the first week of September, there were 4,080 reported cases of chikungunya fever, bringing the total since the introduction of this virus just months ago to 16,430 reported cases (more than the number of reported dengue fever cases).

Both dengue and chikungunya are transmitted by mosquito bites. Travellers to areas where these viruses are active can reduce their risk of exposure by taking all necessary precautions to avoid mosquito bites. Many persons with these infections do not seek medical care and are not reported to health authorities. There may be many more cases in the community than the reports indicate.
