In total, 301 persons were tested for antibodies to Schmallenberg virus by virus neutralization test. All sera tested negative, whereas high levels of antibody were found in serum from an infected animal that was used as a control.

The study population consisted of 234 persons working or living on SBV-infected farms, and 67 veterinarians – all with known exposure to SBV-infected herds. Of these, 229 persons had direct exposure to newborn calves, lambs and/or birthing materials from SBV-infected herds, and 150 persons reported exposure to biting insects. We conclude that there is no evidence for zoonotic infection.
