Bluetongue is a non-contagious, vector-transmitted viral disease of ruminants, mainly sheep, less frequently other of domestic and wild ruminants. Disease symptoms are characterized by inflammation of the mucous membranes, congestion, swelling and hemorrhages. The virus is spread from one animal to another via bites from culicoides midges. There are 24 serotypes known of the Bluetongue Virus (BTV). The virus is present in a broad range of countries, particularly those located near the equator between 40°N and 35°S. In recent years, Bluetongue has spread to Northern Europe, causing substantial economic losses in affected countries. Bluetongue can spread quickly and result in serious disease outbreaks. It is an OIE (Office International des Epizooties) listed disease.
Human health risk
There are no known risks to human health from this disease.
Bluetongue can have a severe impact on the livestock economy of a country or region, mainly through trade restrictions. Direct costs associated with morbidity of sick animals include weight loss, reduced milk yield, abortion and associated veterinary costs.
Early detection of the virus is imperial to containing the spread of the disease. The Ingezim BTV MILK is used for the specific detection of antibodies to the BTV VP7 protein in milk samples. The test can be used for both tank and individual milk samples.
