Abstract
To the Editor: After unexpected emergence of bluetongue virus serotype 8 in northern Europe in 2006 (1), another arbovirus, Schmallenberg virus (SBV), which is transmitted by Culicoides spp. biting midges, emerged in Europe in 2011 and caused disease outbreaks among ruminants (2). Nonspecific clinical signs such as fever, decreased milk production, and diarrhea were associated with acute infection in cattle, and late abortions and birth defects in newborns were associated with infection of pregnant cows, ewes, and goats (2,3).

France has been the country most affected: it had 2,650 Schmallenberg virus (SBV)-infected farms [5]
Summary
HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. As of August 1, 2012, a total of 5,701 infected farms were reported in Europe (2,498 sheep farms, 3,124 cattle farms, and 79 goats farms) (www.survepi.org/cerepi/). France has been the country most affected: it had 2,650 SBV-infected farms [5], (i.e., in which >1 malformed offspring was positive for SBV by real-time reverse transcription PCR [RT-PCR] on 1,128 sheep farms, 1,505 cattle farms, and 17 goat farms).
