“…Flock size is often found to be a risk factor for infectious disease and outbreak occurrence in farmed animals ( 37 , 38 ). However, we did not find a significant association between poultry flock size and AIV occurrence in active surveillance data.…”

Exploring the risk factors of avian influenza (AI) occurrence helps us to monitor and control the disease. Since late 2020, the number of avian influenza outbreaks in domestic and wild birds has increased in most European countries, including Denmark. This study was conducted to identify potential risk factors for wild birds and poultry during the epidemic in 2020/2021 in Denmark. Using Danish AI surveillance data of actively surveyed poultry and passively surveyed wild birds from June 2020 to May 2021, we calculated geographical attributes for bird locations and assessed the potential risk factors of AI detections using logistic regression analyses. 4% of actively surveyed poultry and 39% of passively surveyed wild birds were detected with AI circulating or ongoing at the time. Of these, 10 and 99% tested positive for the H5/H7 AI subtypes, respectively. Our analyses did not find any statistically significant risk factors for actively surveyed poultry within the dataset. For passively surveyed wild birds, bird species belonging to the Anseriformes order had a higher risk of being AI virus positive than five other taxonomic bird orders, and Galliformes were of higher risk than two other taxonomic bird orders. Besides, every 1 km increase in the distance to wetlands was associated with a 5.18% decrease in the risk of being AI positive (OR (odds ratio) 0.95, 95% CI 0.91, 0.99), when all other variables were kept constant. Overall, bird orders and distance to wetlands were associated with the occurrence of AI. The findings may provide targets for surveillance strategies using limited resources and assist in risk-based surveillance during epidemics.

“…For example, Pangilinan et al (2017) analyzed the spatial distribution of dengue in the National Capital Region and identified significant clusters in the northern cities such as Caloocan, Malabon, Navotas, and Valenzuela. On the other hand, Murao et al (2018Murao et al ( , 2019 used spatial clustering methods such as the average nearest neighbor (ANN), Moran's I, and hotspot analysis in determining the spatial distribution of rotavirus A and other enteropathogens that were detected in backyard swine production sites in Davao City. The analysis identified geographical and temporal patterns in the clustering of infections, which can be used to formulate targeted interventions in order to maximize impact while optimizing resource allocation.…”

Rabies is a neglected tropical disease that continues to be a public health threat despite the government’s intention to eliminate it by 2022. Specifically, Davao City has implemented the Intensified Rabies Control Program (IRCP), but animal rabies remains endemic, primarily due to canine transmission. Understanding the dynamics of rabies and its control is critical in formulating strategies to hasten disease eradication. This study utilized hotspot analysis on reported canine rabies cases in Davao City from 2005–2017 to determine the spatiotemporal behavior of the disease pre- and post-IRCP. Around 42% of the barangays have had at least one reported case of canine rabies, most of which were owned dogs (82.0%) and unvaccinated or non-updated vaccination (80.1%). Using the Getis-Ord statistic, five hotspot clusters were detected during pre-IRCP, which was reduced to three new clusters in post-IRCP – all of which were highly populated barangays (> 9,000 residents). The hotspot clusters shifted to neighboring areas with recurrent hotspot barangays located at the junction of this shift, suggesting spillover mediated by the hotspots. The number of rabies cases (mean per barangay of 0.797 pre-IRCP and 0.610 post-IRCP), proportion of affected barangays (33.5% pre-IRCP and 30.2% postIRCP), and rate of improper vaccination (mean per barangay of 31.8% pre-IRCP and 28.8% post-IRCP) did not significantly decrease post-IRCP, suggesting the need to boost the vaccination program and responsible pet ownership. There was no systematic geographical distribution of rabies control programs, hence prioritizing high-risk areas through hotspot analysis provides an efficient alternative to addressing the problem
