Derived implications for herd testing and surveillance.

Surveillance objective	Proposed approach
Detection of BoHV-1 antibodies in a population	Concentrate test capacity on older age-cohorts
Detection of recent BoHV-1 circulation in a population	Concentrate test capacity on the youngest age-cohort without maternal immunity but with epidemiological contact with older latently infected animals
Monitor efficiency of vaccination and other control measures	Observe the annual increase in the age of the age-threshold cohort based on the seroprevalence profile
