Getah virus (GETV) is an emerging zoonotic virus that can infect humans and many mammals through mosquitoes. In this study, a novel pathogenic GETV strain, GDQY2022, was isolated from a pig farm in Guangdong Province, China. Sequence comparisons and phylogenetic analysis showed that GDQY2022 belongs to group III (GIII) and was most closely related to strain HeN202009-2, with 99.

PRRSV remains one of the most prevalent pathogens affecting the pig industry, because of its complex infection profile and highly heterogeneous genetic and recombination characteristics. Therefore, a rapid and effective PRRSV detection method is important for the prevention and control of PRRS.

- Group A rotaviruses are significant causes of diarrhea in piglets and humans, with the newly identified GDJM1 strain causing high morbidity (60%) and mortality (21%) in piglets in China in 2022.
- Genetic analysis of GDJM1 revealed it has a mixed genome with genes closely related to both porcine and human rotavirus strains, indicating it may have originated from genetic reassortment between the two species.
- This finding signifies the first report of a human-porcine reassortment rotavirus strain in mainland China, highlighting its potential for cross-species transmission and the need for monitoring.
