Design outcomes

Primary

Measure	Time frame
- Seroprevalence of TBEV IgG-antibodies among Employees of nature management organisations in the Netherlands. Through the questionnaire, the seroprevalence will be adjusted for previous exposure to TBEV abroad and vaccinations that can cross-react in TBEV-serology. - Risk factors for exposure (e.g. location, tick bites) associated with presence of TBEV antibodies.	—

Secondary

Measure	Time frame
For this part is no funding available yet. - Seroprevalence and risk factors for exposure to other possible occupational (e.g. other tick-borne) infections. - Seroprevalence of TBEV IgG-antibodies among the general population of the Netherlands (using available sera and questionnaire data from Pienter 2 or 3).	—
