Multicenter outpatient study reveals pathogen dynamics and co-infection patterns in acute respiratory infections, suggesting surveillance improvements.

Key Points

The study aims to investigate the spectrum of pathogens causing acute respiratory infections and their epidemiological features in Yunnan Province.
Collected throat swab samples from ARI patients at fever clinics of 23 hospitals biweekly.
Analyzed demographic information alongside pathogen detection using real-time PCR.
Examined seasonal variations and pathogen interactions in the population.
Identified 28 respiratory pathogens, with an overall detection rate of 33.86% for viruses and 63.16% for bacteria and fungi.
Influenza A virus and Human rhinovirus were among the most frequently detected across age groups.
Co-infection rates with other pathogens were 13.26% for IAV, 10.88% for SARS-CoV-2, and 18.88% for Mycoplasma pneumoniae.
