Dhaka's dengue season now stretches from May well into November. The mosquito bites during daylight, so night-time protection alone leaves most of the risk untouched.
01
Clear standing water twice a week
The larval cycle takes about seven days, so a twice-weekly sweep breaks it completely.
- Flower pot trays and vases
- Air-cooler and refrigerator drip trays
- Roof drains, buckets and unused tyres
- Construction debris on balconies
02
Protect during the day
Use repellent on exposed skin, wear long sleeves in the early morning and late afternoon, and keep a net over anyone resting during the day.
03
Warning signs after fever settles
The dangerous phase often begins as the temperature falls. Severe abdominal pain, persistent vomiting, bleeding gums, black stools or sudden lethargy need emergency assessment immediately.
Key takeaways
- Empty still water every three to four days
- Aedes bites in daylight — protect accordingly
- Deterioration usually comes as fever drops
