In South Korea, HPAI outbreaks have recurred since the first case was confirmed in December 2003, with multiple virus subtypes (H5N1, H5N8, and H5N6) affecting domestic poultry farms. Among poultry species, domestic ducks play a crucial role in viral transmission due to their heightened susceptibility and asymptomatic shedding, increasing the risk of unnoticed outbreaks and environmental contamination. To mitigate the impact of HPAI, South Korea implemented the Duck Farming Restriction Policy, limiting duck farming activities during high-risk winter months (November to March). This study evaluates the preventive effectiveness of this policy using a Bayesian time-series modeling approach based on longitudinal outbreak data from 2003 to 2024. The analysis includes key epidemiological variables such as number of confirmed cases and outbreak durations. Our findings provide the first scientific evidence supporting the effectiveness of seasonal duck farming restrictions in reducing HPAI incidence. While global HPAI prevalence has increased significantly since 2020, South Korea has maintained stable or declining outbreak trends, suggesting that proactive control strategies play a crucial role in disease mitigation. These results emphasize the importance of adaptive biosecurity policies in controlling HPAI and offer valuable insights for future pandemic preparedness in the poultry sector.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"247 ","pages":"Article 106722"},"PeriodicalIF":2.4,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145757553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In several low- and middle-income countries (LMIC), limited bTB surveillance and technologies to minimise milk-borne zoonoses put dairy consumers at high risk of bTB infection. Surprisingly, LMIC consumers are seldom investigated, which represents a significant knowledge gap that undermines existing efforts to mitigate zoonotic tuberculosis. We conducted a cross-sectional study in Bhutan where bTB control measures are lacking and raw dairy is widely consumed to assess dairy consumers’ awareness and their knowledge, attitudes, and practices (KAP) regarding bTB. We enrolled 347 participants at the eight milk outlets operating in the capital city to determine the level of awareness about bTB among this group and characterise their KAP towards bTB. Only 17.3 % of the participants had heard of bTB. Majority (90.1 %) of them knew there is treatment of tuberculosis (TB) in Bhutan and TB is curable (72.5 %). However, 70.1 % had misconception that infected people cannot appear healthy, and only 12 % knew bTB is zoonotic. Only 26 % and 24 % perceived milk and dairy products as high risk respectively compared to 56.5 % for meat and 85.8 % for consuming diseased animals.

The CVOs also discussed surprising and challenging phenomena, and what they learned. Qualitative analysis was conducted on interview transcriptions. Most CVOs had similar decision-making processes. They followed established protocols and national legislation aligned with WOAH international standards, relying on multidisciplinary teams of experts in science, economics, policy, and law, and those with knowledge of local field conditions, for guidance. Insufficient information and conflict between scientific evidence and political/economic pressure were common themes. Although stressful, most CVOs were committed to their work and felt they made valuable contributions towards both animal and human health. The findings suggest that regardless of background or specific geographical context, CVOs follow established protocols and need to have the ability to make informed subjective judgements as part of their decision making. Thus, CVO qualifications include subject matter knowledge and specific leadership qualities, which need to be considered when making CVO appointments.

Despite the importance of working donkeys for sustaining livelihoods there are no systematic classifications of these populations. The aim of this study was to classify and characterise donkey systems in Ethiopia using household-level questionnaire data which included donkey ownership, husbandry, use and local environment data, through multiple factor and hierarchical cluster analysis. Household questionnaire data from 241 donkey-owning households in three districts of Ethiopia were used. Three distinct clusters of donkey ownership were identified: ‘Domestic-Pastoral’; ‘Domestic-Agricultural’ and ‘Commercial’. Differences between systems are primarily influenced by donkey purpose, environmental (agro-ecological) factors, and husbandry practices. Constraints associated with donkey ownership varied across clusters: households in the commercial system reported higher incidence of injuries and welfare concerns, in the pastoral system the main constraints were drought and feed shortage, and domestic-agricultural households reported infectious diseases as the main challenge.

A better understanding of how infection patterns of these viral pathogens occur in growing pigs and their impact on productivity measures would help drive improved preventative and control measures for these pathogens. This study was conducted with the objectives to: (1) describe patterns of infection dynamics of PRRSV and swine enteric coronaviruses, (2) determine the impact of introductions and timing of introductions of PRRSV and SeCoV on wean-to-market mortality, average daily gain, and feed conversion, and (3) compare the economic performance of groups of growing pigs with different timing of introductions and pathogen combinations of PRRSV and SeCoV. The pathogen status and timing of the introduction of PEDV, PDCoV, and PRRSV for 75 groups of pigs that originated from negative sow farms were determined by collecting eight oral fluid samples every two weeks per group of pigs and tested by RT-PCR. The timing of introduction for those pathogens was categorized as nursery (3–10 weeks of age), early finisher (11–21 weeks of age), and late finisher (22–33 weeks of age.) Regression analyses were used to compare mortality, average daily gain (ADG), and feed conversion (FC) between pathogen combinations and time of pathogen introductions. A production and economic model was used to determine differences in net profit per pig placed using least squares means of productivity differences from the regression analysis. Wild-type PRRSV was detected in 96 % of the groups of growing pigs, and 37 % became positive for SeCoV. Groups of pigs with multiple pathogens had significantly increased mortality compared to groups with single pathogen introductions. PRRSV introduction in the nursery or early finisher phase or SeCoV introduction in the nursery phase resulted in significantly higher mortality than later introductions, and nursery introductions of SeCoV impacted ADG and FC. Compared to negative groups, the net profit of groups with pathogen introductions was decreased due to increased mortality and reduced ADG and FC, with the most significant differences resulting from pigs with a nursery introduction of SeCoV.

We collected data on 129 CM cases detected by automatic milking system (AMS) and confirmed by herdsman from three farms in Belgium (n = 2) and the Netherlands (n = 1). The CM severity was assessed in four dimensions: production (maximum relative milk loss for the inflamed and uninflamed quarters separately), somatic cell count (deviation from cow-level baseline), clinical (mild, moderate, severe clinical symptoms), and pathogen (cultures from the inflamed quarter). We explored the relations between these dimensions and examined the impact of farm, parity, and lactation stage (LS). Our findings revealed that severity dimensions were positively correlated, with correlations from 0.30 to 0.50. The strongest correlation between dimensions occurred between the production dimension in inflamed and uninflamed quarters. Severity in the somatic cell count dimension exhibited the stronger correlation with production severity for uninflamed quarters and pathogen severity compared to other dimensions, and the clinical dimension showed the strongest association with the production dimension for uninflamed quarters. Additionally, farm, parity, and LS were found to influence both the severity within certain dimensions and the interrelationships among them. These results suggest that, although CM severity scores across the four dimensions are positively correlated, clear variations exist. Combining the four scores could help to capture the full scope of CM by simultaneously assessing the severity of cases across these dimensions.
