Advice for Travellers

WNV is spread by mosquitoes. All travellers should be advised to practice Mosquito Bite Avoidance, especially from dusk till dawn during peak transmission times and when epidemics are known to be occurring. No vaccine is available against WNV.

NOTE: WNV can also be passed on by blood transfusion, consequently blood donors that have visited a WNV risk area four months prior to donation may have their donation tested for WNV. The Scottish National Blood Transfusion Service have produced a leaflet which details information about blood donation after travel:
