What is Dengue?

Dengue is a viral infection spread by mosquitoes. It is common in many tropical and subtropical areas. The illness can cause mild to severe symptoms. In some cases, it can become life-threatening. Early care helps prevent serious problems. According to the World Health Organization (WHO), millions of people get Dengue each year.

Symptoms of Dengue

Dengue symptoms often appear four to ten days after a mosquito bite. Not everyone will have all symptoms. However, most people notice signs quickly. Watch for these common Dengue symptoms:

High fever, often sudden

Severe headache, especially behind the eyes

Pain in muscles, bones, or joints

Nausea or vomiting

Skin rash, which may appear a few days after fever starts

Mild bleeding, such as nosebleeds or gum bleeding

Feeling very tired or weak

Sometimes, Dengue can become severe. This is called severe Dengue or Dengue hemorrhagic fever. It can cause serious bleeding, organ failure, or shock. Seek help right away if you notice severe belly pain, trouble breathing, or bleeding that will not stop.

Causes and Transmission

Dengue is caused by the Dengue virus. There are four types of this virus. Mosquitoes, mainly Aedes aegypti, spread the virus. When a mosquito bites a person with Dengue, it picks up the virus. Then, it can pass the virus to another person through a bite. You cannot catch Dengue directly from another person.

In addition, Dengue spreads more during rainy seasons. This is because mosquitoes breed in standing water. Therefore, keeping your surroundings clean helps reduce risk.

Diagnosis of Dengue

Doctors use several ways to diagnose Dengue. If you have symptoms, your doctor will ask about your travel and health history. Next, they may order blood tests. These tests look for the Dengue virus or signs your body is fighting it. Early diagnosis is important. It helps guide the right treatment and prevents complications. If you wonder how is Dengue diagnosed, remember that only a healthcare provider can confirm it.

Treatment Options

There is no specific medicine to cure Dengue. However, most people recover with proper care. Treatment for Dengue focuses on easing symptoms and preventing problems. Your doctor may suggest:

Resting as much as possible

Drinking plenty of fluids to avoid dehydration

Taking pain relievers like acetaminophen (paracetamol)

Avoiding medicines like ibuprofen or aspirin, as they can increase bleeding risk

In severe cases, hospital care may be needed. Doctors will watch for signs of bleeding or shock. Quick treatment can save lives.

Prevention Tips

Because there is no vaccine for all types of Dengue, prevention is key. You can lower your risk with these Dengue prevention tips:

Use insect repellent on skin and clothing

Wear long-sleeved shirts and long pants

Sleep under mosquito nets, especially during the day

Keep windows and doors closed or use screens

Remove standing water from buckets, pots, and tires

Change water in flower vases often

These steps help reduce mosquito bites and stop the spread of Dengue.

When to See a Doctor

If you have a high fever and live in or have traveled to a Dengue area, see a doctor. Early care is important. You should also seek help if you notice:

Severe belly pain

Repeated vomiting

Bleeding from nose or gums

Blood in vomit or stool

Feeling very weak or confused

These signs may mean severe Dengue. Quick medical care can prevent serious problems.
