Schmallenberg virus among female lambs, Belgium, 2012

Emerg Infect Dis. 2013 Jul;19(7):1115-7. doi: 10.3201/eid1907.121768.

Abstract

Reemergence of Schmallenberg virus (SBV) occurred among lambs (n = 50) in a sheep flock in Belgium between mid-July and mid-October 2012. Bimonthly assessment by quantitative reverse transcription PCR and seroneutralization demonstrated that 100% of lambs were infected. Viremia duration may be longer in naturally infected than in experimentally infected animals.
