Understanding Dengue: Symptoms, Causes, Diagnosis, Treatment, and Prevention

What is Dengue?

Dengue is a viral infection spread by mosquitoes. It is common in many tropical and subtropical areas. In fact, the World Health Organization (WHO) reports that millions of people get dengue each year. Because dengue can cause mild to severe illness, it is important to know the facts. Early awareness helps you stay safe and healthy.

Symptoms of Dengue

Dengue symptoms often appear four to ten days after a mosquito bite. However, not everyone will feel sick. Some people may have mild symptoms, while others may feel very unwell. Watch for these signs:

High fever (often sudden)

Severe headache

Pain behind the eyes

Muscle and joint pain

Nausea or vomiting

Skin rash (may appear a few days after fever)

Mild bleeding (such as nosebleeds or gum bleeding)

Sometimes, dengue can become severe. This is called severe dengue or dengue hemorrhagic fever. In these cases, symptoms can include severe stomach pain, frequent vomiting, bleeding, or trouble breathing. If you notice these, seek help right away.

Causes and Transmission

Dengue is caused by the dengue virus. Mosquitoes, mainly the Aedes aegypti species, spread this 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. Because these mosquitoes are active during the day, you can get bitten at any time. Also, dengue does not spread directly from person to person.

Diagnosis of Dengue

Doctors use several methods for dengue diagnosis. First, they ask about your symptoms and travel history. Next, they may order blood tests. These tests check for the dengue virus or your body’s response to it. Early diagnosis helps doctors give the right care. According to the Centers for Disease Control and Prevention (CDC), timely testing is important for proper dengue fever treatment.

Treatment Options for Dengue

There is no specific medicine to cure dengue. However, most people recover with proper care. Doctors focus on easing symptoms and preventing complications. Here are common steps for dengue fever treatment:

Rest as much as possible

Drink plenty of fluids to avoid dehydration

Take acetaminophen (paracetamol) for pain and fever

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

In severe cases, hospital care may be needed. Doctors may give fluids through a vein or treat bleeding. Always follow your doctor’s advice for the best results.

Prevention Tips for Dengue

Because there is no vaccine for everyone, prevention is key. You can lower your risk by avoiding mosquito bites. Here are some simple ways to help prevent dengue:

Use mosquito repellents on skin and clothing

Wear long-sleeved shirts and long pants

Sleep under a mosquito net, especially during the day

Keep windows and doors closed or use screens

Remove standing water around your home, as mosquitoes breed there

Change water in flower pots and birdbaths often

Additionally, community efforts to control mosquitoes can make a big difference. Working together helps protect everyone.

When to Seek Medical Help

Most dengue cases are mild, but some can become serious. If you or someone you know has dengue symptoms and starts to feel worse, act quickly. Seek medical help if you notice:

Severe stomach pain

Repeated vomiting

Bleeding from nose or gums

Blood in vomit or stool

Difficulty breathing

Extreme tiredness or confusion
