Schmallenberg is a viral disease that primarily affects livestock, particularly sheep, cattle, and goats. It was first identified in Germany in 2011 and is transmitted by biting midges, which are small flying insects. The disease can lead to symptoms such as fever, reduced milk production, and, in pregnant animals, birth defects in offspring. The Schmallenberg virus is not harmful to humans, but it poses significant economic challenges for farmers due to the impact on animal health and productivity. Vaccines have been developed to help control the spread of the virus, and ongoing research aims to better understand its effects and transmission.
