A cross sectional survey was conducted involving 354 farm poultry workers on 85 randomly selected commercial poultry farms in high density poultry farm areas in Pakistan to estimate the sero-prevalence of H5, H7 and H9 and to identify the potential risk factors for infection with the avian influenza virus. A haemagglutination inhibition test titre at 1:160 dilution was considered positive, based on WHO guidelines. The estimated sero-prevalence was 0% for H5, 21.2% for H7 and 47.8% for H9. Based on a generalized linear mixed model, the significant risk factors for H7 infection were area, type of farm and age of poultry worker. Risk of infection increased with the age of poultry workers. Compared with broiler farms, breeder farms presented a greater risk of infection (odds ratio [OR]=3.8, 95% confidence interval [CI]: 1.4, 10.1). Compared with the combined Khyber Pakhtunkhwa Province and Federal area, North Punjab had higher observed biosecurity measures and presented a lesser risk of infection (OR=0.3, 95% CI 0.1, 0.9). Biosecurity should therefore be enhanced (especially in breeder farms) to reduce the occupational risks in poultry farm workers and to decrease the risk of emergent human-adapted strains of AI H7 and H9 viruses.

Aim: The study was conducted to determine the seroprevalence of bovine viral diarrhea virus (BVDV) and hematological features in crossbred dairy cattle in Chittagong, Bangladesh. Materials and Methods: The antibody against BVDV in crossbred dairy cattle serum was detected by indirect enzyme-linked immunosorbent assay. The association of different categorical variables in the prevalence of BVDV has been studied. Blood samples were collected and analyzed to know the hematological variations in the study population. Results: The overall seroprevalence of BVDV in the study area was 51.1% (95% confidence interval [CI], 40.5-61.5). Among different physiological stages of animals, the highest 57.1% (95% CI, 42.2-71.2) prevalence was in case of non-pregnant animals. Aborted cows were found to be significantly (p<0.05) more seropositive 77.8% (95% CI, 52.4-93.6) than the non-aborted cows (77.8%, 95% CI, 52.4-93.6, compared to 44.7%, 95% CI, 33.3-56.6, respectively). Cows having the history of retained placenta were found more positive than without the history of retained placenta (63.2%, 95% CI, 38.4-83.7, compared to 54.7%, 95% CI, 40.4-68.4, respectively). Among the animals of different age groups, BVDV seroprevalence was higher 61.3% (95% CI, 42.2-78.2) in animals of more than 3 years up to 5 years, whereas 32% was in case of 0-1-year-old. Significant variation found in different geographical areas of the study area. Hematological analyses have shown variation between the BVDV positive and negative animals. Conclusion: Seroprevalence of BVDV found to be high in the study area is also economically important and cause significant damage to the production industry. Therefore, it is necessary to conduct effective control measures to reduce the burden of BVDV.
