PASADENA, Calif. - Pasadena Public Health Department (PPHD) encourages the community to take action in preventing mosquito-borne dengue, after the Centers for Disease Control and Prevention (CDC) issued a health advisory notifying the public about the increased risk of dengue virus in the United States. This year, a higher-than-normal number of cases have been identified in travelers who visited countries where dengue is found.
A person can be infected with the dengue virus from an infected Aedes mosquito, a type of mosquito that inhabits Pasadena. About one in four persons develop mild or severe dengue symptoms including fever, nausea, vomiting, rash, and body aches. Symptoms of dengue typically last two to seven days and although severe and even life-threatening illness can occur, most people recover after about a week. There are no specific medicines or vaccines to prevent this disease. Supportive treatment may include monitoring for early signs of serious illness, drinking fluids, and resting.
Risk of exposure to dengue for Pasadena residents remains low. PPHD recommends standard precautions for preventing all mosquito-borne illnesses, such as dengue, and urges the community to take simple steps to reduce mosquito populations and lower the risk of mosquito-borne diseases including:
