Key takeaways
Risk varies within countries
The virus is mainly transmitted by infected Ixodes ticks, with rare food-borne outbreaks linked to unpasteurised dairy products in some regions. Many infections are asymptomatic.
Plan before exposure
Consult official travel-health advice early enough to complete any recommended vaccine course. Tick prevention remains necessary because the vaccine does not prevent other tick-borne diseases.
