During various surveillance programs more than 3500 cloacal swabs and organ samples from songbirds, waterbirds and poultry have been tested for avian influenza using real time RT-PCR. Switzerland carried out the first wildbird monitoring between autumn 2003 and spring 2005. 1053 samples, mostly from songbirds, were tested. LPAI-strains were found in two cases. A second intensified surveillance program started in October 2005 along with the first ban on free range poultry farming. Until the end of April 2006 2455 cloacal swabs from dead wildbirds have been analysed. By the end of february H5N1 was for the first time detected in Switzerland and by the end of march 32 waterbirds have been found positive for H5N1. 146 poultry flocks with a special permission for free range management proved to be Al negative.
