The Symptoms Of Dengue

Jul 11, 2018

A person infected by the dengue virus develops severe flu-like symptoms. The clinical features of dengue fever vary according to the age of the patient.

Individuals should suspect dengue when a high fever (40°C/ 104°F) is accompanied by two of the following symptoms:

Severe headache

Pain behind the eyes

Nausea, Vomiting

Swollen glands

Muscle and joint pains


Symptoms usually last for 2-7 days, after an incubation period of 4-10 days after the bite from an infected mosquito.

Severe dengue is a potentially deadly complication due to plasma leaking, fluid accumulation, respiratory distress, severe bleeding, or organ impairment. The warning signs to look out for occur 3-7 days after the first symptoms in conjunction with a decrease in temperature (below 38°C/ 100°F) include:

Severe abdominal pain

Persistent vomiting

Rapid breathing

Bleeding gums

Blood in vomit

Fatigue, restlessness
