Dengue Fever: Causes, Symptoms, Treatment, Prevention, and Nutrition Support


Dengue fever is a viral infection transmitted by the bite of an infected Aedes aegypti mosquito. It is a major public health problem in tropical and subtropical regions, especially in countries like India. Dengue affects people of all age groups and can range from mild fever to severe, life-threatening conditions. Early diagnosis, proper treatment, and good nutrition play an important role in recovery.


What Is Dengue Fever?
Dengue fever is caused by the dengue virus (DENV), which has four types: DENV-1, DENV-2, DENV-3, and DENV-4. Infection occurs when a mosquito carrying the virus bites a healthy person. Dengue does not spread through direct contact from person to person.


Causes of Dengue

The main cause of dengue fever is the bite of an infected female Aedes mosquito. These mosquitoes usually bite during the daytime and breed in stagnant water found in coolers, pots, tyres, and open containers.
Symptoms of Dengue Fever
Dengue symptoms usually appear 4–10 days after infection. Common signs and symptoms include:
1-High fever
2-Severe headache
3-behind the eyes
4-Muscle and joint pain
5-Nausea and vomiting
6-Skin rash
7-Extreme fatigue
These symptoms may last for several days and should not be ignored.
Warning Signs of Severe Dengue
In some cases, dengue can progress to severe dengue, which requires immediate medical attention. Warning signs include:
1-Severe abdominal pain
2-Continuous vomiting
3-Bleeding from nose or gums
4-Blood in stool or vomit
5-Rapid breathing
6-Low blood pressure
Early hospital care can prevent complications.
Diagnosis of Dengue
Dengue is diagnosed through blood tests such as:
1-NS1 antigen test
2-Dengue IgM and IgG antibody tests
3-Platelet count monitoring
4-Regular blood tests help in assessing disease severity.
Treatment of Dengue Fever
There is no specific antiviral medicine for dengue fever. Treatment focuses on symptom management:
1-Adequate rest
2-Plenty of fluids to prevent dehydration
3-Paracetamol for fever and pain
4-Avoid aspirin and ibuprofen
Hospitalization in severe cases
Prevention of Dengue Fever
Preventing mosquito bites is the most effective way to control dengue:
1-Use mosquito repellents and nets
2-Wear full-sleeve clothing
3-Eliminate stagnant water sources
4-Keep surroundings clean
5-Use window and door screens
Community awareness plays a vital role in dengue prevention.
Nutritional Support for Dengue Fever: Best Diet, Foods to Eat, and Recovery Tips
Nutritional support plays a crucial role in the management and recovery of dengue fever. Dengue is a mosquito-borne viral infection that causes high fever, weakness, dehydration, and a drop in platelet count. While there is no specific antiviral treatment for dengue, a well-planned diet helps improve immunity, maintain hydration, support platelet levels, and speed up recovery.
Importance of Nutrition During Dengue
Proper nutrition during dengue fever helps to:
1-Prevent dehydration
2-Maintain energy levels
3-Support immune function
4-Aid in recovery of platelet count
5-Reduce weakness and fatigue
A light, balanced, and easily digestible diet is recommended during illness.
Fluid Intake in Dengue Fever
Adequate hydration is the most important part of nutritional support in dengue.
Recommended Fluids:
1-Water (small, frequent sips)
2-Oral Rehydration Solution (ORS)
3-Coconut water
4-Lemon water
5-Vegetable soups and clear broths
Fluids help prevent dehydration and maintain electrolyte balance.
Best Foods to Eat During Dengue
Fruits
Fruits provide vitamins, minerals, and antioxidants that support recovery:
1-Papaya
2-Kiwi
3-Orange
4-Pomegranate
5-Apple
Protein-Rich Foods
Protein is essential for tissue repair and immunity:
1-Dal and pulses
2-Curd or yogurt
3-Paneer
4-Soft-boiled eggs
Carbohydrate-Rich Foods
Easily digestible carbohydrates provide energy:
1-Rice
2-Khichdi
3-Oats
4-Toast or plain bread
Vegetables
Vegetables supply essential micronutrients:
1-Bottle gourd
2-Pumpkin
3-Carrot
4-Spinach (well-cooked)
Foods to Avoid During Dengue
Certain foods can worsen symptoms or delay recovery:
1-Fried and oily foods
2-Spicy foods
3-Junk and processed foods
4-Carbonated drinks
5-Alcohol and caffeine

Role of Micronutrients in Dengue Recovery
Vitamin C: Supports immunity and healing
Iron: Helps manage anemia
Zinc: Strengthens immune response
Folate & Vitamin B12: Support blood health


These nutrients should ideally come from natural food sources unless advised by a healthcare professional.

Nutritional support is an essential part of dengue fever management. A diet rich in fluids, fruits, vegetables, and protein helps prevent complications, supports immunity, and speeds up recovery. Along with medical supervision and rest, proper nutrition can significantly improve outcomes in dengue patients
