Table 1 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 |
