Travellers should be advised to:

• Avoid skin contact with fresh water in endemic areas e.g. ponds, lakes and rivers - this includes all water sports (diving, rafting, windsurfing, sailing.
• Swim only in protected swimming pools or safe seawater.
• Avoid drinking infected water.
• Wear protective footwear when walking in soil, especially if it is damp or water logged.
• Attend for screening on return if exposure has occurred, even if asymptomatic.
