Monsoons offer a much-needed relief after long, hot summer days, however, they bring along an upsurge in mosquito-borne diseases such as dengue fever. Each year, a significant number of people show symptoms of a dengue infection and while most people recover with appropriate care, some may develop severe dengue, which can be life-threatening and requires prompt medical attention.
What is Dengue Fever?
Dengue fever is a viral illness transmitted by an infected female Aedes aegypti mosquito. These mosquitoes generally bite during the day time, and breed in containers and other sites that collect stagnant water around homes, offices and construction areas.
The majority of people get better within one or two weeks, but some get very sick with severe dengue, which can be life-threatening and requires urgent hospital care.
7 Dengue Symptoms and Warning Signs You Should Never Ignore
1. Sudden High Fever
An abrupt onset of high fever is one of the earliest symptoms of dengue fever, with temperatures reaching 39–40°C (102–104°F). The fever comes on suddenly and can last from 2 to 7 days.
2. Severe Headache and Pain Behind the Eyes
Dengue commonly causes a severe headache accompanied by pain or pressure behind the eyes (retro-orbital pain). The eye pain may become more noticeable when moving the eyes.
3. Extreme Muscle and Joint Pain
Dengue is popularly known as breakbone fever due to the intense pain it inflicts in the bones and muscles.
4. Skin Rash
A reddish skin rash may appear after the 3rd-4th day of fever and occurs over the face, neck, chest and abdomen. It usually fades away as the fever progresses.
While these symptoms are common in dengue, certain warning signs require prompt medical evaluation as they may indicate worsening illness or progression to severe dengue -
5. Persistent Vomiting or Severe Abdominal Pain
Ongoing vomiting or severe abdominal pain should never be ignored.
Persistent vomiting and severe abdominal pain or tenderness are important warning signs that require prompt medical assessment.
6. Bleeding from the Gums, Nose, or Easy Bruising
Bleeding from the nose or gums, blood in vomit or stool, or unusual bruising requires prompt medical assessment.
7. Extreme Weakness, Restlessness, or Breathing Difficulty
Marked weakness, restlessness, fainting or difficulty breathing can indicate worsening illness and require urgent medical assessment.”
Other Dengue Infection Symptoms
Apart from the symptoms mentioned above, dengue may cause fatigue, loss of appetite, nausea, vomiting, chills and mild bleeding or bruising.
How to Identify Dengue
Doctors evaluate:
- Clinical symptoms
- Recent mosquito exposure
- Duration of fever
- Physical examination
- Laboratory investigations
Laboratory testing can help confirm dengue infection, depending on the day of illness and the test being used.
Dengue Test: When Should You Get Tested?
If you have a fever and a number of dengue symptoms, see your doctor immediately.
Depending on the duration of illness, your doctor may recommend:
- NS1 antigen or molecular testing, particularly during the first 3-5 days of illness.
- Dengue IgM antibody testing, which becomes useful from around day 4–5 onward
- Complete Blood Count
These tests help diagnose dengue and monitor blood counts and disease progression.
Why Does Dengue Platelet Count Matters?
A lot of attention is given to the dengue platelet count alone, but the Platelet count alone does not reliably indicate the severity of dengue.
Doctors monitor:
- Platelet count
- Haematocrit levels
- Bleeding Symptoms
- Vital signs, hydration status, urine output
A falling dengue platelet count should always be interpreted along with other clinical findings rather than in isolation.
Dengue Treatment
There is no specific antiviral medicine for dengue at present. Dengue treatment mainly focuses on supportive care and preventing complications.
Treatment may include:
- Adequate hydration ( ORS etc), guided by the patient's clinical condition
- Fever and pain management with paracetamol, when appropriate
- Regular monitoring of platelet counts and blood tests
- Hospital admission in severe cases
Avoid aspirin and NSAIDs such as ibuprofen and diclofenac unless specifically advised by a doctor, as they may increase the risk of bleeding.
Dengue Prevention Tips
Preventing mosquito bites remains the most effective way to reduce dengue risk.
Following are a few simple measures for preventing dengue:
- Eliminate stagnant water around your home.
- Wear full-sleeved clothing, especially in the daytime.
- Apply mosquito repellents.
- Install screens on windows and doors.
- Sleep under mosquito nets where needed.
- Cover water storage containers.
- Regularly empty, clean or cover coolers, flower pots, buckets and other containers that can collect water.
Community participation plays a major role in dengue prevention, particularly during the monsoon season.
When Should you Visit a Hospital?
Seek immediate medical care if you experience:
- Severe abdominal pain or tenderness
- Persistent vomiting
- Bleeding from the nose, gums, vomit or stool
- Extreme weakness, restlessness or drowsiness
- Difficulty breathing
- Reduced urine output
- Cold/clammy extremities or fainting
- Confusion or altered consciousness
Early recognition and treatment with appropriate medical care leads to better recovery and less complications.
Conclusion
Identifying the dengue warning signs can be a vital step towards preventing severe dengue illness. Although the majority of patients fully recover with appropriate supportive care, ignoring early signs of dengue or delaying treatment may increase the risk of complications.
If you notice persistent fever and symptoms of dengue such as severe body pain, rash, bleeding, pain in the abdomen, or dizziness, seek medical attention at once. Early medical evaluation, appropriate supportive care and regular follow-up can help reduce the risk of complications.
