“…10 Comparatively, the HCoSV genus is categorized into six genetic groups (A−F), 12,13 consisting of over 33 genotypes. 14 SAFV and HCoSV are globally distributed, affecting countries including but not limited to: China, Thailand, Japan, Denmark, Italy, South Korea, and Kuwait. 15 Although SAFV and HCoSV are often associated with a coinfection of other gastroenteritis causing viruses such as norovirus (NoV), rotavirus (RVA), adenovirus (AdV), enterovirus (EV), or human bocavirus (HBoV), 15,16 there are previous reports of sole infection by SAFV or HCoSV resulting in gastroenteritis.…”

Saffold virus (SAFV) and human cosavirus (HCoSV) are emerging viruses of the Picornaviridae family. They have been shown to associate with gastrointestinal infection and more recently these viruses have also been demonstrated to associate with other clinical infections such as the respiratory tract, cardiovascular system, and the cerebral ventricular system. In this study, 2459 stool specimens collected from pediatric patients admitted to hospitals with acute gastroenteritis from January 2017 to December 2022, were screened for SAFV and HCoSV utilizing reverse transcription‐polymerase chain reaction. Positive samples were then characterized into genotypes via nucleotide sequencing and bioinformatic analysis. Of the 2459 samples, 21 and 39 were positive for SAFV (0.9%) and HCoSV (1.6%), respectively. Three genotypes of SAFV were identified—SAFV‐1 (38%), SAFV‐2 (24%), and SAFV‐3 (38%). Two genetic groups of HCoSV were identified—HCoSV‐C (97%) and HCoSV‐A (3%), demonstrating a large increase of HCoSV‐C as compared to those reported previously from the same geographical region in Thailand. This study provides the prevalence of SAFV and HCoSV genotypes in Chiang Mai, Thailand during a period of 6 years from 2017 to 2022.
