Lumpy skin disease (LSD) is an infectious viral disease with major economic impacts on the animal wealth
in different countries and it became endemic in Egypt. The present study was carried out to investigate the prevalence
of LSD in El-Qalyubia governorate, Egypt, and the related risk factors. In total, 665 blood samples were collected from
diseased and apparently healthy animals to detect positive cases. The prevalence of LSD was higher in cattle (36.7%)
than in buffalo (15.2%). The animals of age 1-2 years and over 2 years showed a higher prevalence of LSD (42.2% and
34.9%, respectively) than young animals of age less than one year (26.3%). The prevalence was higher in summer and
spring (37.7% and 34.1%, respectively) than in the winter season. Also, the highest prevalence of LSD was reported at
a high THI level >80 (37.6%). Regarding the locality, Benha, Qaha, and El-Khanater El-Khayria showed the highest
prevalence of LSD (45.6%, 44.4%, and 38.4% respectively). Also, the prevalence of LSD in non-vaccinated animals
(50%) was higher than in vaccinated animals (34.3%). A univariate logistic regression model was applied to evaluate the
risk factors of LSD, followed by forward stepwise multivariate logistic regression. The final multivariate model revealed
that the seroprevalence of LSD was significantly associated with animal species and age. Cattle and animals of age 1-2
years have a higher likelihood to be infected with the LSD compared with their contemporaries (OR = 4.08 and 2.35; P =
>0.001 and |
