Abstract

In year 2006, unusual clustering of cases caused by calicivirus was reported from several EU member states (Germany, Netherlands, Denmark, Ireland, Finland, Norway). Various foods (raw vegetables, fruits, cultivated shells, etc.) may be contaminated at the location of cultivation; this is called primary contamination. Secondary contamination is when infected persons transmit the virus to the foods (e.g. bakery products) with contaminated hands.In Hungary the year 2006 was definitely the year of calicivirus outbreaks, the majority of which were detected in hospitals, elderly homes and children communities. The number and prevalence of outbreaks showed relatively high difference by counties. The outbreaks confirmed our conviction that without suitable and available laboratory methodology the agent could remain unknown. Furthermore, a general and controlled surveillance system is needed, which enables the rapid detection and elimination of gastrointestinal outbreaks of viral origin in collaboration with adequate laboratories.
