Dengue: Causes, Symptoms, Prevention, and Treatment

Dengue is a serious mosquito-borne disease that affects millions of people worldwide. In severe cases, it can lead to dangerous complications such as internal bleeding and organ failure. Understanding how to prevent and manage dengue is crucial for protecting yourself and your loved ones.

In this article, we’ll explore what dengue is, its symptoms, prevention methods, and available treatments.


1. What Is Dengue?

Dengue is a viral infection transmitted by the Aedes aegypti mosquito. The virus has four strains (DENV-1, DENV-2, DENV-3, DENV-4), meaning a person can get dengue more than once in their lifetime.

How Dengue Spreads:

🦟 The Aedes mosquito bites an infected person and then transmits the virus to others.
🌅 The mosquito is most active early in the morning and late in the afternoon.
💧 Standing water in containers, gutters, and plants provides a breeding ground for mosquitoes.

Tip: Dengue is not transmitted from person to person—only through mosquito bites.


2. Symptoms of Dengue

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

Common Dengue Symptoms:

🤒 High fever (above 39°C or 102°F)
💥 Severe headaches and eye pain
💪 Muscle, joint, and bone pain (nicknamed “breakbone fever”)
🔴 Skin rash and red spots
🤢 Nausea, vomiting, and loss of appetite

Severe Dengue Symptoms (Dengue Hemorrhagic Fever):

Severe abdominal pain
🩸 Bleeding from the nose, gums, or under the skin
💧 Persistent vomiting with blood
😵 Dizziness or confusion (signs of shock)

Tip: If you or someone you know shows severe symptoms, seek immediate medical attention!


3. How to Prevent Dengue

Since there is no specific cure for dengue, prevention is the best defense.

Steps to Prevent Dengue:

🚫 Eliminate mosquito breeding sites by removing standing water from buckets, tires, and containers.
🦟 Use insect repellent with DEET or picaridin.
🛏 Sleep under mosquito nets, especially in high-risk areas.
👕 Wear long-sleeved clothing to reduce exposure to bites.
🏡 Install screens on windows and doors to keep mosquitoes out.

Tip: Mosquitoes lay eggs in clean, stagnant water, so check your surroundings regularly!


4. Dengue Treatment: What to Do If You Get Infected

There is no specific antiviral treatment for dengue, but symptoms can be managed with proper care.

How to Treat Dengue at Home:

💧 Drink plenty of fluids to avoid dehydration.
💊 Use acetaminophen (paracetamol) for fever and pain relief (avoid ibuprofen and aspirin, which increase bleeding risk).
🛏 Get plenty of rest to help the body recover.

When to Go to the Hospital:

🚨 If you experience severe symptoms like persistent vomiting, bleeding, or dizziness.
🏥 If dehydration occurs (dry mouth, reduced urination, extreme fatigue).

Tip: Dengue can become life-threatening, so monitoring symptoms is essential!


5. Is There a Dengue Vaccine?

Yes! Some countries offer dengue vaccines, such as Dengvaxia and Qdenga. However, these vaccines are usually recommended for people who have had dengue before to prevent severe cases.

Who Should Consider the Vaccine?

✔ People living in high-risk areas
✔ Those with a history of previous dengue infections
❌ Not recommended for people who have never had dengue before (risk of severe reactions)

Tip: Consult a doctor to see if the dengue vaccine is right for you.


6. Dengue vs. Other Mosquito-Borne Diseases

Dengue symptoms can be confused with other illnesses, such as:

DiseaseMain SymptomsKey Differences
DengueHigh fever, severe joint pain, rash, bleedingNo specific treatment, risk of severe cases
ChikungunyaJoint pain, fever, headache, swellingJoint pain lasts longer than in dengue
Zika VirusMild fever, rash, conjunctivitisDangerous for pregnant women (risk of birth defects)
MalariaCyclic fever, chills, sweatingCaused by parasites, not a virus

Tip: If you suspect dengue, get tested to rule out other mosquito-borne diseases.


Final Thoughts

Dengue is a serious but preventable disease. By eliminating mosquito breeding sites, using repellents, and recognizing symptoms early, you can protect yourself and your community from infection.

If you develop any severe symptoms, seek medical help immediately—early treatment can save lives!

Start protecting yourself today by checking your home for standing water and using mosquito protection!
