Origin of infection: unknown or inconclusive.
After the third infected horse was euthanised on 19 May 2005, a first screening test on the horses in the centre gave negative results on 20 June 2005. This serological test marks the first step of eradication of infection. Another serological test will be performed on 21 September 2005. The results will be available at the end of September. If the results are negative, the centre will be declared free from infection and the restriction measures lifted.
All the serological tests performed in equestrian centres in neighbouring districts have given negative results. No other clinical suspicion has been reported.
