Symptoms of dengue fever include fever, nausea, vomiting, rash, and body aches. Symptoms usually last two to seven days and most people recover in about a week, but serious and life-threatening illness can occur, PPHD said.
There are no drugs or vaccines to prevent dengue fever, and most treatments include rest, hydration, and monitoring for early symptoms.
The Los Angeles County Vector Management District advised people to remove all standing water. Most mosquitoes lay their eggs on the water surface, but Aedes mosquitoes lay their eggs on the sides of containers, so simply dumping the water may not be enough to get rid of them.
Residents are encouraged to eliminate plant trays and keep repellents on hand to prevent the spread of Aedes mosquitoes.
“Mosquitoes breed in hot weather, increasing the risk of bites and mosquito-borne diseases,” Davis says. “People should follow these simple steps to reduce their exposure to mosquitoes and the risk of mosquito bites: 1) Use insect repellent on you and your family. 2) Avoid mosquitoes laying eggs. Remove any standing water around your home where they can spawn and breed; and 3) Use or install window and door screens to prevent mosquitoes from entering your home. Please fix it.”
