  • Background: HCoV causes illness ranging from the common cold to life-threatening pneumonia. Little is known about the burden of HCoV infection in hospitalized children.

    Methods: We conducted a retrospective cohort study of hospitalized children <18 years with HCoV infection from 5/2012-4/2013 at Primary Children’s Medical Center. Demographic, clinical, and financial data were obtained from Intermountain Healthcare’s Enterprise Data Warehouse. Multiplex PCR for 17 respiratory viruses including 4 HCoV subtypes was performed for children admitted with respiratory illness.

    Results: Of 1,247 hospitalized children tested, 105 (8.4%) were positive for HCoV. HCoV subtypes included HKU1 (55%), OC43 (38%), NL63 (7%) and 229E (4%). Thirty-three children (31%) had a chronic medical condition, 28 (27%) were admitted to the ICU, 9 (9%) required mechanical ventilation and 1 (1%) died (Table). One child had bacteremia (H. influenzae type B) and 2 had UTI (E. coli). The median hospital length of stay was 2 days (IQR: 2-4) and did not vary by age. The median cost per hospitalization was $5,387 (IQR: $3,390-9,385) and was similar across age groups. A second virus, most commonly RSV, was detected in 50% of cases. Children co-infected with RSV were younger than children infected with HCoV alone (P<0.01). ICU admission, hospital cost and length of stay were similar among children with HCoV alone and those co-infected with RSV.

    Conclusion: HCoV was frequently detected in children hospitalized for respiratory illness. Viral co-detection was common, making it difficult to establish the independent impact of HCoV. However, the similar outcomes in children with HCoV alone compared with those with HCoV and RSV detected suggests that HCoV detection is associated with a substantial clinical and economic burden.
