What is Dengue?

Dengue is a viral infection spread by mosquitoes. It is common in tropical and subtropical areas. According to the World Health Organization (WHO), millions of people get dengue each year. Although most cases are mild, some can become severe. Early detection and care can help prevent complications. Dengue is also known as “breakbone fever” because it can cause severe joint and muscle pain.

Common Symptoms of Dengue

Dengue symptoms usually appear four to ten days after a mosquito bite. Not everyone will have all symptoms. However, knowing the signs can help you seek care quickly. Common dengue symptoms include:

High fever, often up to 104°F (40°C)

Severe headache

Pain behind the eyes

Joint and muscle pain

Nausea or vomiting

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

Mild bleeding, such as nosebleeds or gum bleeding

Sometimes, dengue can become severe. Warning signs include severe stomach pain, repeated vomiting, bleeding, or feeling very tired. If you notice these, seek medical help right away.

Causes and Transmission of Dengue

Dengue is caused by the dengue virus. There are four types of this virus. Mosquitoes, mainly Aedes aegypti, spread the virus. These mosquitoes bite during the day, especially early morning and late afternoon. If a mosquito bites a person with dengue, it can carry the virus and infect others. Dengue does not spread directly from person to person. However, living in areas with standing water increases your risk. Mosquitoes breed in water collected in containers, tires, or flower pots.

How Dengue is Diagnosed

Doctors diagnose dengue based on symptoms and travel history. However, lab tests confirm the infection. These tests look for the virus or antibodies in your blood. Early diagnosis is important. It helps doctors manage symptoms and prevent severe illness. According to the Centers for Disease Control and Prevention (CDC), you should tell your doctor if you have traveled to areas where dengue is common.

Treatment Options for Dengue

There is no specific medicine to cure dengue. Most people recover with rest and care at home. However, some may need hospital care if symptoms are severe. Treatment focuses on relieving symptoms. Common dengue fever treatment steps include:

Resting as much as possible

Drinking plenty of fluids to prevent dehydration

Taking acetaminophen (paracetamol) for pain and fever

Do not take aspirin or ibuprofen, as these can increase bleeding risk. If you feel worse or develop warning signs, seek medical help quickly.

Prevention Tips for Dengue

Preventing mosquito bites is the best way to avoid dengue. You can lower your risk by following these tips:

Use mosquito repellents on exposed skin

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 containers, tires, and flower pots

Change water in vases and pet dishes often

In some countries, a dengue vaccine is available for people who have had dengue before. However, it is not for everyone. Ask your doctor if the vaccine is right for you.

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 can prevent serious problems. You should also seek help if you have:

Severe stomach pain

Persistent vomiting

Bleeding from the nose or gums

Blood in vomit or stool

Feeling very tired or restless

These may be signs of severe dengue, which needs urgent care.

In summary, dengue is a serious illness but can be managed with early care. Prevention is key. Consult Dr.  M. Srinivasa Reddy  if you suspect dengue or need personalized advice.
