West Nile virus is spread by mosquito bites and can cause a flu-like illness and sometimes, severe disease.

Advice for Travellers

WNV is rare in travellers. There is no vaccine against WNV.

When visiting areas affected by WNV, you should:

• practice mosquito bite avoidance measures at all times
• seek medical advice if you develop a sudden onset of flu-like symptoms with a high temperature (fever) following travel to a risk area

Note for blood donors: if you have recently travelled to an area with WNV transmission, you may need to be tested for WNV before donating blood.

• see the Scottish National Blood Transfusion Service website for further details
