    This research objective was to determine the Infectious Bovine Rhinotracheitis (IBR) prevalence in Latacunga, Cotopaxi province. IBR is an infectious and contagious disease caused by Bovine Herpesvirus Type 1 (BoHV-1) that significantly impacts the productivity and livestock herds reproduction. By using a cross-sectional observational design, 100 blood samples were collected from cattle owned by small-scale producers in 14 areas in Latacunga. Serological testing for antibodies against viral glycoprotein B was performed in the laboratory using an indirect ELISA assay. The results showed an overall IBR prevalence with 9%, with specific seropositivity identified in Mulaló area (60%), Pastocalle (25%), and Joseguango Bajo (12.5%), while the remaining 11 parishes reported no positive cases. Based on these details, an epidemiological map was created showing the specific active infection clusters locations within the territory. Using statistical analyses with Fisher's exact test and the chi-square test, the association between seropositivity and the sex variables, age, race, physiological status, and vaccination was evaluated, and it was determined that none of these variables showed a statistically significant association (p > 0.05), concluding that the virus distribution is uniform and those characteristics are independent. The alternative hypothesis was confirmed, thereby verifying the presence of IBR in the area. It is concluded that Latacunga keeps a low prevalence compared to regional data; however, latent viral circulation requires the immediate implementation of strategic vaccination plans, animal movement control and biosecurity reinforced measures to safeguard the livestock area's economy.
