Re-emergence of severe acute diarrhea syndrome coronavirus (SADS-CoV) in Henan, central China, 2023
Copyright © 2024 Elsevier B.V. All rights reserved..
Severe acute diarrhea syndrome coronavirus (SADS-CoV) was first detected in Guangdong province of China in 2017. And yet from May 2021 to Jun 2023, there were no SADS-CoV outbreaks. In this study, we reported the recent outbreak of SADS-CoV in China on Jun 2023. Phylogenetic analysis showed the novel strain was derived from the ongoing transmission and evolution of SADS-CoV in China, rather than a separate cross-species transmission from bats. Also, the novel strain was found to participate in a recombant event as a minor parent and a missing base in the genome was discovered indicating an novel evolutionary pathway. Through virulence assays in piglets, we further determined that novel strain (SADS-CoV/HNNY/2023) was a highly virulent SADS-CoV strain with typical clinical symptoms: acute diarrhea, vomiting, rapid weight loss. Therefore, the re-emergence of SADS-CoV strains should be brought to people's attention.
