The percentage of calves testing positive (LP+HP) was 53.7% (95% Confidence interval (CI): 52.6%-54.8%), with 39.6% (95% CI: 38.6-40.7%) testing HP (n=3309) while 14.1% (95% CI: 13.5-15.0%) of calves tested LP (n=1188). Of 281 epi-units sampled, all calves sampled tested negative in only 2 epi-units (0.7% (95% CI: 0.1-2.5%)) and more than 25 calves tested positive in 29 epi-units (10.3% (95% CI: 7.0-14.5%))
