Advice for Travellers
West Nile virus infection is transmitted by Culex mosquitoes which bite mainly from dusk to dawn. Reservoir hosts are usually birds. Most infections are asymptomatic and severe infection is rare. West Nile virus infection is rarely reported in travellers.
Risk is greatest in those undertaking outdoor activities. Travellers should take precautions to prevent mosquito bites especially during summer months.
