From: A four year longitudinal sero-epidemiological study of bovine herpesvirus type-1 (BHV-1) in adult cattle in 107 unvaccinated herds in south west England

Figure 1

Unadjusted age-specific profile of the mean BHV-1 antibody seroprevalence and 95% CI by quarter year (up to 2 years old) and year (after 2 years old) for seropositive herds. Herds are dichotomised by presence of seroconversion in the period of study. All cattle greater than 10 years of age were categorised in one age group. Data came from all visits to BHV-1 unvaccinated herds (Dataset A, see methods section).
