Het gaat blijkbaar om een nieuwe variant van het virus. Dat niet wordt verspreid via muggen - zoals eerder gemeld - maar vermoedelijk via knutten: kleine mugjes.
Knutten kunnen ook de drager zijn van o.a. het blauwtongvirus en van Afrikaanse Paardenpest.

New Orthobunyavirus detected in cattle in Germany
Er blijven nog veel vragen open, nader onderzoek is nodig.
O.a. de relatie tussen het gevonden virus en de ziekteverschijnselen bij koeien moet nog definitief worden aangetoond.
Ook wil men uitzoeken of het gaat om een virus dat nieuw geïntroduceerd is in Europa of dat het er al was, maar nog niet eerder gevonden.
In Nederland is het virus niet gevonden.

New Orthobunyavirus detected in cattle in Germany
Information of the Friedrich-Loeffler-Institut
last updated November 2011
The Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health (FLI), has first detected a virus of the genus Orthobunyavirus in cattle in Germany. Comparative analyses of the genetic material lead to the assumption that the virus belongs to the group of Akabane-like viruses. Based on the geographic origin of the sample, the virus was provisionally named „Schmallenberg virus“. Further investigations for characterization of the virus and epidemiological investigations will follow.
Orthobunyaviruses of cattle are widely distributed in Oceania, Australia and Africa and, as a rule, initially cause very mild clinical symptoms. If pregnant animals are infected, however, temporarily delayed, sometimes considerable congenital damages, premature births and reproductive disorders may occur. Akabane-like viruses are mainly transmitted by biting midges.
At present, it is not possible to confirm or exclude any causal relationship between the detection of „Schmallenberg virus“ and the observed clinical picture. Furthermore, it is unclear whether this exotic virus has been newly introduced or whether orthobunyaviruses have already been present in cattle in Europe for some time. To assess the significance of the detection of this virus, extensive additional investigations are required.
