Dengue Fever: Causes, Symptoms, Treatment, and Prevention
Introduction
Dengue fever is a mosquito-borne viral disease that affects millions of people every year, especially in tropical and subtropical regions. It is spread by the bite of an infected Aedes aegypti mosquito. In recent years, dengue has become a growing global health concern due to climate change and urbanization.
Understanding dengue fever is very important because early detection and proper care can save lives.

What Causes Dengue Fever?
Dengue fever is caused by the dengue virus, which has four different types (DENV-1, DENV-2, DENV-3, and DENV-4). A person becomes infected when bitten by an infected mosquito.
Important facts:
• It is not spread from person to person directly
• Mosquitoes breed in clean, stagnant water
• Infection can occur multiple times with different virus types

Symptoms of Dengue Fever
Symptoms usually appear 4–10 days after being bitten by an infected mosquito.
Common symptoms include:
• High fever (up to 40°C / 104°F)
• Severe headache
• Pain behind the eyes
• Muscle and joint pain
• Nausea and vomiting
• Skin rash
• Fatigue and weakness
In severe cases, dengue can develop into dengue hemorrhagic fever, which can be life-threatening.

Warning Signs of Severe Dengue
Seek medical help immediately if you notice:
• Severe abdominal pain
• Continuous vomiting
• Bleeding (nose, gums, or under the skin)
• Difficulty breathing
• Extreme weakness or restlessness
Early treatment is very important in preventing complications.

───

Treatment of Dengue Fever
There is currently no specific antiviral cure for dengue. Treatment mainly focuses on relieving symptoms.
Recommended care:
• Drink plenty of fluids (water, oral rehydration solution)
• Get enough rest
• Use paracetamol (acetaminophen) for fever
• Avoid aspirin and ibuprofen (they may increase bleeding risk)
Most patients recover within 1–2 weeks with proper care.

───

Prevention of Dengue Fever
Prevention is the most effective way to control dengue.
Here are key prevention methods:
• Remove stagnant water around homes
• Use mosquito nets and repellents
• Wear long-sleeved clothing
• Install window screens
• Keep surroundings clean
Community efforts are also important in controlling mosquito breeding sites.

Conclusion
Dengue fever is a serious but preventable disease. Awareness, early detection, and proper mosquito control can significantly reduce the risk of infection. By taking simple preventive measures, individuals and communities can protect themselves and reduce the spread of the disease.
