Summary
Bavaria
Area of Science:
- Veterinary epidemiology
- Infectious disease control
- Bovine viral diarrhea virus 1 (BVDV-1) research
Context:
- Bavaria initiated a Bovine Viral Diarrhea Virus 1 (BVDV-1) eradication program in 1986, transitioning to a compulsory program in 1998.
- Eradication success rates increased from under 50% in 1986 to 87% of farms by 2002.
- Ongoing surveillance involves bulk milk and blood serology using indirect and gB ELISA tests.
Purpose:
- To review the current challenges in BHV-1 eradication efforts in Bavaria.
- To discuss potential strategies for improving the effectiveness of the BHV-1 eradication program.
- To identify key obstacles in eliminating BHV-1 from heavily infected herds.
Summary:
- The BHV-1 eradication program in Bavaria has shown progressive success, with 87% of farms achieving BHV-1-free status by 2002.
- Approximately 100,000 cattle remain infected, predominantly in heavily infected herds (5% of total herds).
- Eradicating BHV-1 from these high-prevalence herds presents the most significant challenge, while preventing new infections is more manageable.
Impact:
- Highlights the difficulties in eradicating BHV-1 from persistently infected cattle herds.
- Suggests that preventing new BHV-1 infections is a more achievable goal within the current program.
- Provides insights for refining BVDV-1 control strategies in cattle populations.
