Dengue Fever: Symptoms, Warning Signs, Treatment and Prevention
Dengue is now endemic in Bangladesh, with cases climbing every monsoon (June–September) in Dhaka and most district towns. Knowing the warning signs — and what NOT to take — saves lives.
What are the symptoms of dengue?
Symptoms usually start 4–7 days after the bite of an infected Aedes mosquito: sudden high fever (102–104°F), severe headache, pain behind the eyes, intense muscle and joint pain, nausea, and a skin rash. Most patients recover in about a week with rest and fluids.
Which warning signs mean you must go to hospital?
The dangerous phase often begins when the fever drops, around day 3–6. Go to a hospital immediately if you notice:
- Severe abdominal pain or persistent vomiting
- Bleeding from gums or nose, blood in vomit or stool
- Extreme weakness, restlessness or drowsiness
- Cold, clammy hands and feet
- Little or no urine for 6+ hours
How is dengue fever treated at home?
There is no specific antiviral for dengue — treatment is supportive:
- Paracetamol only for fever and pain (e.g., 500 mg as advised). Never take aspirin, ibuprofen, diclofenac or other NSAIDs — they increase bleeding risk.
- Drink plenty of fluids: water, ORS, daber pani (coconut water), soup. Aim for clear, light-coloured urine.
- Rest, and recheck CBC (platelets and haematocrit) as your doctor advises.
How can you prevent dengue?
- Empty standing water every 3 days — flower tubs, AC trays, fridge trays, tyres, roof tanks.
- Aedes mosquitoes bite in daytime — use repellent and mosquito nets even for daytime naps.
- Wear full-sleeve clothing during outbreak season; install window nets.
If you have fever during dengue season, get an NS1 test on day 1–3 and see a doctor early. Book a doctor's appointment on ChamberBD instead of waiting in long queues with a sick patient.
