Knowledge, attitudes, and practices regarding brucellosis in a rural population: A cross-sectional study

Abstract

Brucellosis is recognized as a significant global zoonotic infection that disproportionately affects low-income settings. A community cross-sectional survey was carried out in a rural setting of northwest Iran between February and May 2023. Rural individuals were interviewed according to a questionnaire with questions about demographic characteristics, knowledge, attitudes, and practices relating to human brucellosis. We employed descriptive statistics to study knowledge, attitudes, and practice patterns. In addition, we applied a multivariable logistic regression model to assess potential predictors of knowledge, attitudes, and practice related to brucellosis using odds ratios and 95% confidence intervals. Among 700 participants, 91.1% were aware of brucellosis, and 85.7% identified cows, sheep, and goats as primary transmission sources. 75.6% and 78.7% recognized transmission risks via unpasteurized and raw milk products. 60.5% understood the benefits of boiling milk and using gloves. Attitudinally, 64.3% perceived higher risk for livestock owners and supported practices like milk pasteurization (70.5%), protective gear (84.4%), handwashing (92.2%), and animal vaccination (71.0%). 90% expressed a need for more information. In practice, 44.8% exclusively consumed boiled and pasteurized milk, 37.8% consumed fresh cheese, and 92.2% solely consumed thoroughly cooked animal meat. Logistic regression revealed that higher education and no prior history of the disease correlated with good knowledge and attitudes, while older participants displayed inappropriate practices compared to their younger counterparts. This study highlights the reasonably high awareness of brucellosis, particularly regarding transmission sources and preventive measures. However, the gaps in knowledge, attitudes, and practices still exist, with education level emerging as a significant factor. To improve prevention practices, tailored interventions addressing age-related disparities are necessary.
