- Epidemiology and Emergence of Schmallenberg Virus Part 2: Pathogenesis and Risk of Viral SpreadPublication . Esteves, Fernando; Mesquita, João; Nóbrega, Carmen; Santos, Carla; Monteiro, António; Cruz, Rita; Helena, Vala; Coelho, Ana CláudiaSchmallenberg virus (SBV) is a novel Orthobunyavirus causing mild clinical signs in cows and malformations in aborted and neonatal ruminants in Europe. SBV belongs to the family Bunyaviridae and is transmiĴed by biting midges. This new virus was identified for the first time in blood samples of cows in the city of Schmallenberg in North-Rhine Westphalia in November 2011. Since then, the virus spread to several European countries. Here, we describe the pathogenesis and the risk of viral spread in the Portuguese territory.
