When planning a trip, you’re probably more concerned with finding cheap flights, choosing where to stay, and working out what to see and do rather than worrying about mosquito bites. But while some travel risks are easy to overlook, the West Nile virus is one worth knowing about before you go depending on where you plan to travel. Spread primarily through infected mosquitoes, Wat Nile virus has been detected across much of the world, including destinations in the United States, southern Europe, the Middle East, Africa, and parts of Asia. While the risk varies depending on where and when you travel, a few simple precautions can help reduce your chances of infection.
