A BREECH IN BIOSECURITY PROTOCOL FINGERED FOR SPREAD OF BOVINE VIRAL DIARRHEA.

Bovine viral diarrhea that affected about 5,000 cattle of which 500 were destroyed in Germany,indicates a breech of bio security protocol as the cause of high incidence. Bovine Viral Diarrhea (BVD) leads to severe disease and significant economic losses Caused by the Bovine Viral Diarrhea Virus (BVDV). Bovine Viral Diarrhea suppresses the immune system and causes a variety of symptoms, including respiratory problems, infertility, and abortion. "A dairy farmer first noticed a reduction in milk yield, respiratory symptoms, nasal discharge, fever, sporadic diarrhea and sudden deaths -- these symptoms were also noted on other farms as the infection spread, but did not immediately indicate BVD as the cause," said Dr. Jörn Gethmann, lead author of the study from Friedrich-Loeffler-Institute. "We were surprised by the high morbidity and mortality an induced by a BVDV strain in this outbreak." The researchers supported the competent local authorities in tracing the spread of the virus. They visited eight farms and obtained data on a further 13 farms. They discovered that the virus was not transmitted directly by infected cattle, but mostly by people such as vets and traders who were moving between farms. "We were surprised to see the effective transmission to other farms without persistently infected animals involved," commented Dr. Gethmann. Bio security is very important at all levels of production; a simple hand washing ,wearing protective clothing,tyre dips,foot baths and use of protective gloves will prevent spread of infectious agents.
