Dengue Fever in Bangladesh: A Growing Crisis
Bangladesh recorded over 300,000 dengue cases in recent years making it one of the world's worst-affected countries. Dhaka city alone accounts for the majority of cases. The Aedes aegypti mosquito that spreads dengue breeds in clean stagnant water and bites during the day.
How Mosquito Nets Prevent Dengue
Dengue mosquitoes bite mainly during early morning and late afternoon. Using a mosquito net during afternoon naps and at night significantly reduces bite exposure. Studies show insecticide-treated nets (LLIN) reduce mosquito-borne infection rates by up to 50%.
Other Dengue Prevention Methods
- Remove stagnant water from flower pots, water coolers, and blocked drains
- Wear full-sleeve clothing during morning and evening hours
- Use window screens and door screens
- Apply mosquito repellent when outdoors
- Sleep under a net even during the day for afternoon naps
Recognising Dengue Symptoms
High fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. If you have these symptoms seek medical care immediately.

What time do dengue mosquitoes bite?
Aedes mosquitoes are most active 2 hours after sunrise and 2 hours before sunset. Using a net during afternoon naps is especially important.
Which is better for dengue prevention — net or spray?
Both together are most effective. A net provides continuous protection during sleep while spray covers outdoor exposure.
