Dengue symptoms

After being bitten by a dengue mosquito infected with the dengue virus, it usually takes between 3 to 14 days to start experiencing symptoms.

During this time you are able to pass the virus on to other dengue mosquitoes, so if a dengue mosquito bites you it can catch the virus and go on to infect other people. That is why it is very important to visit a doctor as soon as you feel unwell.


Dengue fever has many symptoms, and people usually experience a combination of symptoms. Common symptoms of dengue fever are:

Most symptoms last up to a week and in some cases the fever may return for another 2-3 days. Dengue fever symptoms affect everyone differently. They can range from mild, and can even go unnoticed (often in children), to very severe and potentially fatal. Most people will experience a certain amount of discomfort, regardless of their specific symptoms, and usually need to spend a few days resting at home. This is important, not only for recovery but to reduce the risk of spreading the virus.

Complications include shock (collapsing due to internal fluid loss) and hemorrhage (heavy bleeding), which is usually associated with severe dengue.
