AB  - BACKGROUND: Porcine reproductive and respiratory syndrome is a highly infectious 
      disease of swine caused by PRRS virus (PRRSV). OBJECTIVES: To evaluate the 
      prevalence of PRRSV antibodies in the four districts of hilly and terai regions 
      of Nepal. Toassess the farm characteristics through a questionnaire interview of 
      farmersregarding management practices and PRRS. METHODS: A cross-sectional study 
      was conducted from July 2020 to June 2021 to determine the sero-prevalence of 
      PRRSV in pigs. A total of 180 porcine serum samples were collected from 23 pig 
      farms and tested for PRRSV antibodies by ELISA. Alongside, farm characteristics 
      were also assessed through questionnaire to determine the level of biosecurity 
      measures in the farm, knowledge of the disease and possible control mechanisms. 
      RESULTS: Out of 180 samples, 37 were tested positive resulting the overall 
      sero-prevalence of 20.5%. There was significant association between different 
      districts (p < 0.05) and PRRS prevalence. Prevalence of PRRSV antibody was found 
      higher in Kaski district (10.5%) followed by Sunsari (8.8%) district. Based on 
      age groups, highest prevalence was found in age groups of above 18 months (9.4%), 
      followed by 13-18 months age groups (7.7%). Regarding the knowledge level of the 
      disease, 43% of the farmers responded that they have heard about the disease. 
      Biosecurity practices in the farm was found very poor where only 40% of the farms 
      had disinfectant at the entrance of the farm and 25% pig farmers were found using 
      separate boots while dealing with pigs. CONCLUSIONS: The findings of this study 
      reveal the presence of PRRSV antibodies in pigs of Nepal. In addition poor 
      biosecurity measures, management practices and poor knowledge level about the 
      disease among farmers highly affect in the control and prevention of disease 
      thereby affecting the pig production and productivity. Therefore, government 
      should develop and implement effective control measures and biosecurity programs.
