Tickborne encephalitis (TBE) has been notifiable in Latvia since 1955. In 1993, annual incidence quadrupled from the mean level of the previous two decades (nearly 8 cases per 100 000 population), reaching the highest levels in 1994 and 1995 at 53 cases per 100 000. Since 1999 the incidence has been significantly lower, down to 6.5 cases in 2002, but back up to 15.7 per 100 000 in 2003. About 60% of TBE cases over the last 10 years affected the meninges, about 30% were febrile and 10% had the most severe clinical course, meningoencephalitis.
