Design outcomes

Primary

Measure	Time frame
Presence of antibodies against SBV in this study population together with the absence of antibodies in the historic reference samples from farmers and veterinarians (collected between 2006 and 2010) will be used as indication of past infection among livestock farmers and veterinarians.	—

Secondary

Measure	Time frame
If seropositives are found, seropositivity is the outcome measure for the risk factor analysis. Risk factors include age, gender, individual direct exposure to infected ruminants - especially animals giving birth - use of protective clothing (gloves), risk perception, skin injuries when working with animals, consumption of raw milk or fresh dairy products, medical history, insect-bites etc.. Analysis will also include association of seropositivity with health complaints reported in the questionnaire.	—
