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.
