Family outbreak of alimentary tick-borne encephalitis in Slovakia associated with a natural focus of infection

Abstract
A family outbreak of tick-borne encephalitis involving 7 people, all of them hospitalized, was observed in the district of Považská Bystrica (central Slovakia). The disease was associated with the drinking of unboiled goat milk and tick-borne encephalitis virus was recovered from Ixodes ricinus ticks collected from places where goats were grazing.
