BSE/TSE--the present epidemiologic and diagnostic situation

In 1992, 1994 and 1997, first BSE cases were diagnosed among imported cattle. The first domestic BSE case in Germany was confirmed on 26 November 2000. Altogether 192 cases (7 cases in 2000, 125 cases in 2001 and 60 cases in 2002) were reported (at the date: 7. August 2002). Comparing the BSE situation in Germany with other European countries under consideration of the surveillance schemes applied, Germany has a similar BSE incidence based on 100,000 adult cattle as France and Spain but a higher incidence than neighboring countries like The Netherlands, Austria and Denmark. At present, on average 2,3 cases per week are confirmed in Germany. With respect to the age distribution of the BSE cases, about 84% of all domestic cases confirmed originated out of the years 1995 and 1996 with a accumulation in 1996 (about 53% of all cases). Single BSE cases with the years of birth 1990, 1991 and 1993 demonstrate, that the BSE agent is circulating among the German cattle population at least since the beginning of the nineties. Between 1985 und 7 August 2002, scrapie was diagnosed in 26 sheep flocks in Germany, but alone during the year 2002 (until 7 August 2002) 11 scrapie affected sheep flocks were discovered.
