Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus

# Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in their blood. It can’t be spread directly from one person to another person.

# Symptoms, which usually begin four to six days after infection and last for up to 10 days, may include:

Sudden high fever,
Severe headaches,
Pain behind the eyes,
Severe joint and muscle pain,
Fatigue,
Nausea,
Vomiting,
Skin rash, which appears two to five days after the onset of fever,
Mild bleeding (such a nose bleed, bleeding gums, or easy bruising).

# Diagnosing Dengue Fever
Doctors can diagnose dengue infection with a blood test to check for the virus or antibodies to it. If you become sick after traveling to a tropical area, let your doctor know. This will allow your doctor to evaluate the possibility that your symptoms were caused by a dengue infection.

# Treatment for Dengue Fever
There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor. If you start to feel worse in the first 24 hours after your fever goes down, you should get to a hospital immediately to be checked for complications.
