Understanding Dengue Fever Signs and Symptoms

High Fever

One of the hallmark symptoms of dengue fever is a sudden onset of high fever. This fever can reach temperatures as high as 104°F (40°C) and typically lasts for several days. It’s essential to monitor your body temperature if you suspect dengue.

Severe Headache

Intense headaches are a common symptom of dengue. The pain is often described as severe and is usually concentrated around the forehead and behind the eyes. These headaches can be debilitating and are often accompanied by sensitivity to light.

Joint and Muscle Pain

Dengue fever is often referred to as “breakbone fever” due to the severe joint and muscle pain it causes. This pain can be excruciating, making even simple movements uncomfortable. It may feel as if your bones and muscles are aching.


A rash can develop a few days after the onset of fever. This rash is typically maculopapular, which means it consists of small, red, raised spots. It usually appears on the arms, legs, and chest. The rash may be itchy and is a key indicator of dengue.

Bleeding and Bruising

In some cases, dengue fever can lead to bleeding and bruising. This may manifest as nosebleeds, gum bleeding, or easy bruising. If you notice any unusual bleeding, it’s essential to seek medical attention promptly.

Nausea and Vomiting

Nausea and vomiting are common gastrointestinal symptoms of dengue. These symptoms can contribute to dehydration, which is a concern in dengue cases. Maintaining hydration is crucial during the illness.


Dengue fever can cause extreme fatigue and weakness, which may persist for several weeks even after the acute phase of the illness has passed. It’s essential to get plenty of rest to aid in recovery.

Mild to Severe Symptoms

It’s important to note that dengue symptoms can range from mild to severe. In some cases, the disease can progress to severe dengue, which can be life-threatening. Warning signs of severe dengue include severe abdominal pain, persistent vomiting, rapid breathing, and bleeding.
