RESUMO
In October 2011, a cluster of four tick-borne encephalitis (TBE) cases was identified in Hungary. Initial investigations revealed a possible link with consumption of unpasteurised cow milk sold by a farmer without authorisation. We performed a cohort study including all regular customers of the farmer. Overall, eleven cases (seven confirmed and four suspected) were identified. Customers who had consumed the farmer's unpasteurised cow milk had more than a two-fold increased risk for being a TBE case, although not at statistically significant level.

Between 2003 and 2007, a yearly average of six cases of West Nile virus neuroinvasive infection were diagnosed in Hungary. In 2008, 14 cases have been confirmed by the end of October. In contrast with previous years the infection has now appeared also in the north-western part of the country which is endemic for tick-borne encephalitis.
