Dengue Fever


Dengue fever is a mosquito-borne disease that occurs in tropical and subtropical areas of the world.


The Department of Health (DOH) has recorded a 25% rise in dengue cases or over 7,200 cases in Metro Manila, last July 11, 2018. In the same period in 2017, there were only about 5,800 dengue cases in the region.


Four types of dengue viruses are known to cause dengue hemorrhagic fever. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. When the infected mosquito then bites another person, the virus enters that person's bloodstream. Aedes aegypti is a mosquito that can spread dengue fever.


Dengue fever causes a high fever (400 C) and at least 2 of the following symptoms:
Muscle, bone and joint pain
Pain behind the eyes
Swollen glands

Severe dengue — a life-threatening emergency — includes:
Severe abdominal pain
Persistent vomiting
Bleeding from your gums or nose
Blood in your urine, stools or vomit
Bleeding under the skin, which might look like bruising
Difficult or rapid breathing
Cold or clammy skin (shock)
Irritability or restlessness


Drink plenty of fluids to avoid dehydration from vomiting and a high fever. Call your doctor right away if you develop any of the following:
Decreased urination
Few or no tears
Dry mouth or lips
Lethargy or confusion
Cold or clammy extremities

If you have severe dengue fever, you may need:
Supportive care in a hospital
Intravenous (IV) fluid and electrolyte replacement
Blood pressure monitoring
Transfusion to replace blood loss


Stay in air-conditioned or well-screened housing.
Wear protective clothing.
Use mosquito repellent.
Reduce mosquito habitat.

If possible, travel during times of the day when mosquitoes are less active. Mosquito control programs can also reduce the risk of infection.
