“…In this study, we examined 17,850 samples collected between November 2018 and May 2023 to detect IgM antibodies for 11 respiratory pathogens, namely, RSV, AdV, IAV, IBV, PIV, CVA, CVB, ECHO, MP, CP, and LP. Although previous studies have analyzed the prevalence and genotype of RSV in Guizhou Province, 17 there are few epidemiological investigations of other respiratory pathogens in this region. Therefore, we aimed to help improve understanding of the transmission characteristics of multiple respiratory pathogens in Guizhou Province and their impact on the epidemic dynamics before and after the outbreak of SARS-CoV-2.…”
