Sudden High Fever

A rapid spike in body temperature (104°F or more) is usually the first symptom of dengue fever. If the fever lasts more than 2 days, it's time to get tested.

Severe Headache and Eye Pain

Dengue often causes intense headaches, especially pain behind the eyes. This discomfort may increase with eye movement or bright light.

Muscle & Joint Pain (Breakbone Fever)

The virus causes deep muscle pain and joint aches, giving dengue the nickname "breakbone fever." This symptom is often disabling.

Skin Rash

A red, itchy skin rash appears a few days after fever onset. It may spread over the body and can resemble measles in some cases.

Low Platelet Count

One of the most dangerous effects of dengue is a drop in platelet levels, which can lead to internal bleeding. A CBC test is essential.
