Systematic review estimates pooled prevalence of BoHV-1 in dairy cattle, indicating a rising trend and economic impacts.

To estimate the pooled prevalence of bovine herpesvirus 1 (BoHV-1) infection in dairy cattle in Ethiopia.
Conducted systematic literature searches in multiple databases including PubMed and ScienceDirect.
Analyzed nine studies that tested 5078 dairy cattle using c-ELISA and b-ELISA methods.
Used a random-effect meta-analysis model to generate pooled prevalence estimates.
Estimated overall pooled prevalence of BoHV-1 at 46.02% (95% CI: 33.36 to 58.68).
Higher prevalence observed with c-ELISA at 54.17% (95% CI: 31.62 to 76.71) compared to b-ELISA at 39.56% (95% CI: 26.08 to 53.04).
Temporal analysis revealed prevalence rates of 36.93% from 2018-2021 and 56.63% from 2022-2025.
Highest prevalence recorded in studies with sample sizes between 413-563 at 51.79% (95% CI: 41.37 to 62.21).
Trend analysis suggests a rising incidence of BoHV-1 infection in dairy cattle.
