摘要

In border regions where small ruminants are lifelines, peste des petits ruminants (PPR) remains a silent killer for the small ruminants, undermining food security and rural economies. A cross-sectional survey was conducted between June 2023 and February 2025 in Comilla, Kushtia, Meherpur and Panchagarh districts of Bangladesh. A total of 389 goat blood samples were collected and performed competitive ELISA for peste des petits ruminants virus (PPRV) antibody detection. Among the unvaccinated goats 39.34% (120/305) were found to be seropositive, whereas 48.8% (41/84) was observed in the vaccinated group. Multivariable logistic regression identified several significant risk factors. Goats in Meherpur were significantly more likely to be seropositive (OR = 6.3; 95% CI: 2.74–15.44; p < 0.001) compared to Comilla. Female goats had increased odds of seropositivity (OR = 2.9; 95% CI: 1.67–5.42; p < 0.001) compared to males. Jamunapari goats showed higher odds of infection compared to crossbred goats (OR = 6.6; 95% CI: 1.94–27.64; p = 0.004). Additionally, the extensive rearing system was associated with greater risk (OR = 3.7; 95% CI: 1.89–7.46; p < 0.001). These findings underscore the need for region-specific vaccination strategies, along with strengthened surveillance in high-risk border districts, to support national PPR eradication roadmap.
