Dengue Fever: Symptoms, Warning Signs, Prevention and When to Seek Medical Care
How Can Dengue Be Prevented? The most important preventive measure is reducing exposure to infected mosquitoes.
Kailash Deepak Hospital Dengue is a mosquito-borne viral infection that remains an important health concern in tropical and subtropical regions. It is transmitted mainly through the bite of infected Aedes mosquitoes. According to the World Health Organization, dengue affects millions of people globally each year, and severe dengue can become life-threatening without timely medical care.
Understanding the symptoms of dengue and knowing which warning signs require urgent attention can help patients seek medical care at the right time.
What Are the Common Symptoms of Dengue?
Dengue symptoms usually begin around 4–10 days after infection. Some people have mild symptoms or no symptoms at all.
Common symptoms include:
- High fever
- Severe headache
- Pain behind the eyes
- Muscle and joint pain
- Nausea or vomiting
- Skin rash
- Swollen glands
- Weakness and fatigue
Most people with uncomplicated dengue recover within one to two weeks.
What Are the Warning Signs of Severe Dengue?
A person can sometimes become more seriously ill around the time the fever starts to settle. Warning signs include:
- Severe abdominal pain
- Persistent vomiting
- Bleeding from the nose or gums
- Blood in vomit or stool
- Rapid breathing
- Extreme weakness or restlessness
- Pale or cold skin
- Excessive thirst
These symptoms require immediate medical attention because severe dengue can lead to bleeding, shock, fluid accumulation and organ impairment.
How Is Dengue Diagnosed?
Doctors may use blood tests along with the patient's symptoms, examination and history. The timing of testing can influence which test is most useful.
Because dengue can resemble other infections, self-diagnosis based only on fever is not advisable.
How Can Dengue Be Prevented?
The most important preventive measure is reducing exposure to infected mosquitoes.
Helpful measures include:
- Use mosquito repellents
- Wear clothing that covers the arms and legs
- Use window screens or mosquito nets where appropriate
- Remove stagnant water around homes
- Keep water-storage containers covered
- Take extra precautions during mosquito-active periods
Community mosquito-control measures are also important because Aedes mosquitoes can breed in small collections of standing water.
Why Should Fever Not Be Ignored?
Many illnesses can cause fever, so every fever is not dengue. However, during periods when dengue is circulating, persistent high fever accompanied by severe headache, body pain, nausea, rash or weakness deserves medical evaluation.
People should also avoid taking medicines such as aspirin or ibuprofen without medical advice when dengue is suspected because they may increase bleeding risk. WHO recommends paracetamol for fever and pain in dengue and advises against aspirin and ibuprofen.
