Duration of clinical symptoms in children with acute respiratory infection
Acta paediatrica (Oslo, Norway : 1992)(2023)
Abstract
Aim: To investigate duration of clinical symptoms associated with various respiratory viruses and with the co-detection of respiratory viral and bacterial pathogens.Methods: This prospective cohort study included 737 acutely ill children treated in a paediatric emergency department prior to the COVID-19 pandemic. Nasal swab samples were analysed with multiplex PCR panels for 16 viral and 7 bacterial respiratory pathogens. Parents filled in a questionnaire about the symptoms at the time of the visit and 14 days afterwards.Results: Persistent symptoms 2 weeks after the onset of acute illness were common: 32% of the patients with a coronavirus 229 E, NL63 or OC43 finding, 31% of those with human metapneumovirus and 25% of those with rhinovirus reported ongoing symptoms. At least one symptom lasting more than 4 weeks was observed in 3-4% of the children. Children with viral and bacterial co-detection had a longer duration of fever than those with only viral detection (3.3 days [SD 2.8] vs. 1.6 days [SD 2.4], p < 0.001).Conclusion: Symptoms lasting for more than 2 to 4 weeks appear to be relatively frequent in all respiratory viral infections in children. Viral and bacterial co-detection may increase the duration of illness.
