“…Additionally, before December 2019, RSV infections were more common in children aged 0 to 3 years (Figure 5a), which is in line with previous studies. 1,4,7,17 However, there was a significant increase in the RSV positivity rates among adults over 18 years of age after the outbreak of SARS-CoV-2 (i.e., after January 2020) (Figure 5a). This finding may be associated with reduced exposure risks owing to restricted mobility during the pandemic, during which time children tended to have limited opportunities to engage in outdoor activities.…”

“…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.…”

Objective Acute respiratory infections are a major global public health concern. However, there are few epidemiological studies investigating pathogens associated with respiratory tract infections in Guizhou Province, China. Methods We collected 17,850 blood samples from Guizhou Provincial People’s Hospital between November 2018 and May 2023 to investigate the epidemiological characteristics of respiratory pathogens and their spread during the SARS-CoV-2 epidemic in Guizhou Province. Results We identified influenza virus and Mycoplasma pneumoniae as the predominant pathogens involved in acute respiratory infections in the study area. Immunoglobulin M positivity for respiratory syncytial virus, influenza virus, and M. pneumoniae showed a strong correlation with the clinical diagnosis of pneumonia. Seasonal epidemic patterns were observed for influenza A and B viruses. Following the SARS-CoV-2 outbreak, there was a significant decrease in the positive rates for most respiratory pathogens, particularly influenza A and B, Legionella pneumophila, and respiratory syncytial virus. Conclusion This retrospective study contributes to the epidemiological evidence regarding respiratory pathogens in Guizhou Province, thereby enhancing the surveillance network for respiratory pathogens in China and providing valuable guidance for local hospitals.

Aim: The study aimed to analyze human respiratory syncytial virus (hRSV) strains in nasopharyngeal aspirates obtained retrospectively. Materials & methods: Clinical information of ARI patients (n = 53) was accessed and 2nd hypervariable region of G protein gene of RSV was sequenced and analyzed. Results: Cough (98.1%), fever 40 (75.4%) and shortness of breath 32 (60.3%) were the common symptom. Sequence determination (n = 45) categorized all the strains in ON1 genotype. Potential O- and N- glycosylation were observed at some sites and purifying selections were observed at 274 and 320 codon positions. Conclusion: The study reports replacement of other RSVA genotypes with ON1. The future course of studies should emphasize on clinical implications of presence of hRSVA-ON1 genotype in a given population.
