Abstract Objective To investigate the characteristics of influenza A virus (FluA), influenza B virus (FluB), human rhinovirus (HRV), respiratory syncytial virus (RSV), human adenovirus (ADV) and Mycoplasma pneumoniae (MP) among acute respiratory infection (ARI) cases in the First People's Hospital of Huzhou, so as to provide the basis for formulating prevention and treatment measures for ARI. Methods Gender, age, testing time, and pathogen testing data of ARI cases in the First People's Hospital of Huzhou from April 2023 to March 2024 were collected. The detection rates of FluA, FluB, HRV, RSV, ADV and MP were analyzed across different genders, age groups and seasons. Results A total of 15 788 ARI cases were included, and 8 617 cases were tested positive for at least one pathogen, with a detection rate of 54.58%. Single-pathogen detection was found in 7 913 cases (50.12%), with the detection rates of 14.61% for FluA, 11.86% for MP, 8.46% for FluB, 8.41% for RSV, 4.35% for HRV, and 2.44% for ADV. Mixed-pathogen detection was found in 704 cases (4.46%). MP mixed with other pathogens was the most common, with 335 cases accounting for 47.59% of mixed detections. The single-pathogen detection rate for RSV was higher in males than in females (9.13% vs. 7.64%, P<0.05). The detection rate was higher in the cases aged 5 to <18 years (67.32%) than in the other age groups (all P<0.008). The detection rates were higher in autumn and winter, with 56.99% and 61.59%, respectively (all P<0.008). Conclusions The pathogen detection rate among ARI cases in the First People's Hospital of Huzhou from 2023 to 2024 was relatively high, with FluA and MP being the predominant pathogens. Children and adolescents aged 5 to <18 years were the susceptible population, and autumn and winter were the peak seasons for infection.
