Advice for travellers
Most human WNV infections (70-80%) are mild, subclinical or asymptomatic, but around 1-in-150 cases involve potentially severe neuroinvasive disease. The virus is transmitted by Culex mosquitoes, which feed mainly around dawn and dusk. While the risk of infection for most travellers is generally low, those visiting regions reporting human cases, particularly the peak transmission season, should take measures to avoid mosquito bites.
