Symptoms of Dengue

Reading time: 1 min

The incubation period of the disease is 3-14 days.

Between 40% and 80% of infections are asymptomatic, which means they can go unnoticed.

In cases where there are symptoms, there tends to be a flu-like clinical picture, which includes:

High fever.

Headache (particularly behind the eyes).

Muscular or joint pain.

Nausea or vomiting.

Fatigue.

Diarrhoea.

Skin rash.

These symptoms don’t tend to last for more than ten days, although the convalescence period may be much longer.

In a small number of cases, the patient may develop symptoms of severe dengue. The warning signs may include:

Intense abdominal pain.

Persistent vomiting.

Bleeding nose or gums.

Liquid retention.

Accelerated breathing.

Neurological alterations, lethargy or restlessness.
