Summary: This study analyzed the genetic variations and spread of the classical swine fever virus during outbreaks in Northeast Brazil. The results showed that the virus has a continuous presence in Ceara state and has spread to other states. The Brazilian Northeast virus has specific polymorphisms that differentiate it from viruses isolated in other countries.

Summary: Understanding the impact of bait vaccination in controlling infectious diseases in wildlife is essential. This study developed a model to estimate the impact of bait vaccination against classical swine fever (CSF) in Japanese wild boar. The model estimated a 12.1% increase in antibody prevalence due to vaccination in 2019 and calculated the amount of vaccine distribution required for CSF elimination. The findings highlight the importance of bait vaccination and provide insights for disease control strategies.

Summary: This study evaluated ASF transmission in two regions of France using a stochastic model, showing that the introduction of ASF dramatically impacted wild boar populations. Habitat fragmentation and landscape connectivity were identified as important factors shaping ASF propagation.

Summary: This study estimated the effective range of oral vaccination for wild boars against classical swine fever (CSF) by analyzing the geographical relationship between immune wild boars and vaccination points. The results showed that the effective spatial range of bait vaccination was within 500 meters of the vaccination point. Additionally, investigating susceptible wild boar habitats within a range of at least 1200 meters from a vaccination point before implementation was found to be important.

Summary: African swine fever has had a detrimental impact on China's hog industry, leading to a decline in hog production and significant economic and social effects. This study measures the industrial resilience of 31 Chinese provinces to the shock of African swine fever from 2018 to 2021 and explores the key factors influencing the resilience of the hog industry using Geodetector. The results show that the resistance and recovery periods of the hog industry under African swine fever shock were characterized by poor resilience and improved resilience, respectively. Different provinces exhibited varying levels of resilience based on factors such as slaughter rate, economic level, mortality rate, carcass weight, and culling rate.

Summary: Researchers found that using accelerometer sensors can detect changes in activity patterns and behavioral fingerprints of wild boars infected with African swine fever, allowing for early detection of the disease. This is crucial for timely surveillance and control of animal infections.

Summary: African swine fever (ASF) has spread to European countries since 2007, with Serbia experiencing its first case in 2019. In 2020, ASF was found in wild boars along Serbia's borders with Romania and Bulgaria. Despite biosecurity protocols, ASF was detected in an enclosed hunting ground in 2021. This study analyzes the epidemiological data of the first ASF outbreak in a wild boar population near the Serbian-Romanian border.

Summary: ASF, introduced into Georgia from Africa in 2007, continues to spread through Europe and Asia, with a high socio-economic impact. Control measures focus on removing wild boar carcasses and limiting their movements to reduce density. Some countries like the Czech Republic and Belgium have successfully eliminated ASF using these measures.

Summary: The proportion of seropositive wild boars in Gifu prefecture increased with oral vaccination, with high virus replication and low or non-immune response animals still present after vaccination. Continuous vaccination led to an increase in seroprevalence and a decrease in CSFV-positive animals among wild boars. The epidemiological analysis based on quantitative virological outcomes provides valuable information for improving control measures for CSF in Japan and neighboring countries.

Summary: African swine fever (ASF) has spread across Europe since its introduction in 2007, with the first cases detected in wild boar near the Germany-Poland border. The movement of infected wild boar represents a potential route of introduction, in addition to human activities.

Summary: Classical swine fever has spread widely among wild boars in Japan, and despite the implementation of oral vaccination, infections are still ongoing. This study investigates the landscape elements that influence the uptake of oral vaccines by wild boars. The results indicate that seasonal changes and landscape diversity can affect vaccine uptake.

Summary: This study developed an agent-based modeling approach to simulate management strategies for the effective control of African swine fever (ASF). The results showed that the higher the hunting intensity, the smaller the ASF expansion area, and an annual hunting intensity of 70% is needed to effectively control ASF.

Summary: The study assessed a hypothetical transmission path of African swine fever from Euro-Siberia to NE China, using maximum entropy algorithm for spatial modelling of infected wild boar and the Spatial Distribution Modeller in ArcGIS for plotting Least Cost Paths. The results suggest that infected wild boar could not have reached NE China on 2 August 2018 through the hypothesized overland transmission path due to high costs and long travel time.

Summary: African swine fever is a disease that affects global pork trade and food security. The transmission between wild boar and domestic pigs is not well understood, and the risk factors for transmission at the wildlife-livestock interface are still unclear.

Summary: African Swine Fever is a highly lethal viral disease that has caused significant economic losses in both wild boar populations and the pig industry. Current eradication efforts, such as hunting and carcass removal, have not been successful in completely eliminating the disease. However, a combined approach of a 30% annual hunting rate and intensive carcass removal during a 2-month period in late winter has shown the best results in eradicating ASF.

Summary: The study revealed a high frequency of BATV infections in ruminants in Eastern Germany, with antibodies confirmed in all three species even though viral RNA was not detected. The presence of Gc-derived antibodies in the sera of the animals may serve as a basis for a new serological test for BATV infections.

Summary: The study showed that the monitoring system in Estonia was unable to detect virus circulation and there was no significant accumulation of serologically positive wild boar in temporal connection to the re-emergence of ASFV. Additionally, with the decreasing wild boar population density and ongoing surveillance activities, the circulation of ASFV at a low prevalence was deemed unlikely.

Summary: On a global scale, SARS-CoV-2 poses a serious threat to human health and can also infect companion animals. A study in Germany found that 42.5% of cats and 56.8% of dogs from households with confirmed SARS-CoV-2 cases tested positive for antibodies. Risk factors for cats included the number of infected humans in the household and high contact intensity, while contact with humans outside the household was protective. For dogs, contact outside the household was a risk factor, but reduced contact after human infection was known provided significant protection. There was no significant association between clinical signs in animals and antibody status, and no spatial clustering of positive test results was found.
