What Is Dengue Fever?

Dengue fever is a viral infection transmitted to humans through the bite of infected mosquitoes, particularly in tropical and subtropical regions.

It is one of the most rapidly spreading mosquito-borne diseases worldwide, affecting millions of people every year.

Causes of Dengue Fever

Dengue is caused by the dengue virus (DENV), which is spread through the bite of infected mosquitoes, mainly Aedes aegypti.

Once a mosquito carrying the virus bites a person, the virus enters the bloodstream and begins to multiply.

Risk Factors:

• Living in or traveling to tropical areas
• Previous dengue infection
• Poor mosquito control environments

Symptoms of Dengue Fever

Symptoms usually appear 4–10 days after infection and can range from mild to severe.

Common Symptoms:

• High fever (up to 40°C / 104°F)
• Severe headache
• Pain behind the eyes
• Muscle and joint pain (“breakbone fever”)
• Nausea and vomiting
• Skin rash

Most people recover within a week, but some cases may worsen.

Warning Signs of Severe Dengue

Severe dengue is a medical emergency and can be life-threatening.

Seek immediate medical care if you notice:

• Severe abdominal pain
• Persistent vomiting
• Bleeding (gums, nose, or internal)
• Difficulty breathing
• Extreme fatigue

Complications of Dengue Fever

If not properly managed, dengue can lead to:

• Internal bleeding
• Organ failure
• Shock (dangerous drop in blood pressure)
• Death in severe cases

Treatment of Dengue Fever

There is no specific antiviral treatment for dengue.

Management focuses on:

• Rest and hydration
• Fever control using Paracetamol
• Avoiding medications like aspirin or ibuprofen (to reduce bleeding risk)
• Medical monitoring in severe cases

Early medical care significantly reduces the risk of complications.

Prevention of Dengue Fever

The best way to prevent dengue is to avoid mosquito bites.

Key Prevention Tips:

• Use mosquito repellents
• Wear long-sleeved clothing
• Eliminate standing water
• Use mosquito nets

Vector control remains the most effective strategy to reduce dengue transmission.

Global Impact of Dengue

Dengue affects nearly half of the world’s population, with an estimated 100–400 million infections each year.

This makes it a major public health concern in many countries.

Conclusion

Dengue fever is a widespread but preventable disease. Early recognition of symptoms, proper care, and preventive measures can significantly reduce the risk of severe complications and improve outcomes.
