Prevent mosquito-borne diseases
Practical dengue-prevention steps based on current WHO and Philippine Department of Health guidance.
No single coil, spray or repellent replaces source reduction and early medical consultation. The Philippine Department of Health describes a 4S strategy for dengue prevention and control.
Use the 4S framework
- Search and destroy breeding places: cover water containers and regularly empty, clean or dispose of items that can hold water.
- Self-protection: reduce exposed skin, use suitable repellents as directed and improve barriers such as screens.
- Seek early consultation: contact an appropriate healthcare provider when dengue symptoms or warning signs are suspected.
- Support targeted fogging or spraying: follow local health-authority advice for hotspot or outbreak response.
Check weekly
Walk around the home and workplace after rain. Look at buckets, plant saucers, gutters, discarded containers, roof drains and water storage. Small amounts of standing water can support mosquito development.
