Dengue Fever risk in Phuket

Dengue Fever is a viral illness spread by the Aedes mosquito. It causes high fever, severe headache, joint and muscle pain, and can develop into a more serious form called severe dengue. In Phuket, the risk is elevated due to its tropical climate. The rainy season (May to October) creates ideal breeding conditions. Stagnant water in coconut shells, discarded tires, and construction sites near your accommodation increases mosquito populations. Your risk score of 71/100 means you must take active steps.

Specific local risk factors include Phuket's dense tourism areas, outdoor dining, and early morning and late afternoon peak mosquito activity. Resort gardens and beachfront areas are common breeding sites.

Actionable prevention steps for your trip.

1. Apply DEET-based repellent from dawn to dusk, especially around ankles and neck. Reapply after swimming.

2. Choose accommodations with screened windows and air conditioning. Request mosquito nets if windows are open.

3. Eliminate standing water daily. Check plant pots, buckets, and bathroom drains near your room. Report any stagnant water in hotel gardens to staff.

4. Wear light-colored, long-sleeved clothing during peak hours. Treat clothing with permethrin if possible.

5. Seek immediate medical attention if fever develops with severe headache or pain behind eyes. Avoid aspirin, use paracetamol instead, and ensure adequate hydration.
