    • Abstract:
      Data on people suspected with acute respiratory infections (ARIs) from August 2022 to December 2023 in southern China were analyzed. Following the COVID-19 pandemic, the positive detection rates of respiratory pathogens increased to 56.9%. Influenza A virus (IAV) emerged as the predominant prevalence pathogen (52.1%), followed by Mycoplasma pneumoniae (Mp: 21.2%), and SARS-CoV-2 (11.6%). Mp, IAV, and Human rhinovirus (HRV) infection were the primary etiologies of ARIs patients under age 18, accounting for 49.4%, 48.6%, and 21.7%, respectively. Mp, HRV, Respiratory syncytial virus (RSV), and Adenovirus (ADV) contributed to ARIs cases in virtually every month in this group, with Mp being particularly notable for its consistent presence and high co-infection rate (31.0%). IAV was predominant in the 19 to 59 age group (88.6%), SARS-CoV-2 was responsible for most of ARIs in the elderly group (82.5%). This study provides valuable insights into the dynamic nature of respiratory pathogens post COVID-19 era.
