Overview

Supports targeted viral surveillance in outpatient ARIs; leaves open whether testing improves outcomes in prospective cohorts.

Study Design

Type

Observational (n=426)

Multicenter

Yes

Structured PICO

P
Population
426 outpatients of all ages with acute respiratory infections evaluated at two hospitals in Huzhou, China, to determine viral etiologies.
O
Outcome
Viral etiologies and clinical characteristics of acute respiratory infections

Viruses, particularly influenza A, are major agents of acute respiratory infections among outpatients in Huzhou, China, with significant variation across age groups and seasons.

Limitations

  • Small sample size of 426 outpatients from only two local hospitals, making it difficult to estimate disease severity in detail.
  • Did not test for bacterial pathogens, limiting the comprehensiveness of etiology data and the ability to determine relationships between pathogens and disease severity.
  • Small sample size from only two local hospitals
  • Did not test for bacterial pathogens
