Summary: African swine fever (ASF) has been causing outbreaks in Africa for over a century and since 1957, sporadic outbreaks have occurred outside Africa. The current ASF pandemic, originating from a 2007 outbreak in Georgia, has been particularly devastating. This study collected ASF isolates from samples in Ghana and found that the circulating strains in 2022 were derivatives of the p72 Genotype II pandemic strain, demonstrating the emergence of Genotype II ASFV in Ghana for the first time.

Summary: Asia, with its large swine industry and significant trade connections, is at high risk of being a viral reservoir for African swine fever (ASF). Pig farms and backyard farms with low biosecurity levels are considered critical control points for disease management. Meanwhile, wild boars are a major source of transmission in some countries. Although much research has been done on ASF control in Asia, the overall picture of the epidemic is still unclear.

Summary: China's African swine fever outbreak has had a significant and lasting impact on the hog industry since 2018, and it has not been fully eradicated yet. This article examines the effects of the ASF epidemic on hog production costs and technical efficiency in China using data from the China Agricultural Product Cost-Benefit Compilation. The findings reveal that the outbreak led to a substantial increase in feed, medical, and epidemic prevention costs, as well as a significant decline in technical efficiency. Large-scale hog farms were the most affected, and there were regional variations in the impact on technical efficiency. Future policies should focus on R&D investment, technology promotion, moderate-scale farming, and regional cooperation to improve hog production efficiency.

Summary: This study analyzed the temporal and spatial distribution of African swine fever-positive wild boar carcasses in affected European countries from 2017 to January 2021. The results showed a higher number of cases in southern latitudes between January and April, with no clear temporal pattern in northern latitudes. There was evidence of clustering of ASF-positive carcasses within 2 km and 1 week. The study also identified landscape factors, land use, and wild boar abundance that were associated with the probability of finding ASF-positive wild boar carcasses.

Summary: The study compared the sequencing of the SARS-CoV-2 genome using R9 vs R10 flow cells and a Rapid Barcoding Kit (RBK) vs a Ligation Sequencing Kit (LSK). Results showed that the R9 chemistry had a lower error rate and the LSK provided longer DNA fragments, contributing to a better assembly of SARS-CoV-2 despite potential impacts on variant detection in a R10 flow cell. The study suggests that nanopore sequencing could be valuable in the epidemiological surveillance of SARS-CoV-2.
