Background: Respiratory viral infections are a major cause of morbidity and hospitalization in young children. Nevertheless, the population burden of respiratory viral infections, especially asymptomatic cases, is not known due to the lack of prospective community-based cohort studies with intensive monitoring.
Methods: To address this gap, we enacted the PREVAIL cohort, a CDC-sponsored birth cohort in Cincinnati, Ohio where children were followed from birth to 2 years of age. Weekly text surveys were administered to mothers to record acute respiratory illnesses (ARIs), which were defined as the presence of cough or fever (≥38oC). Weekly mid-turbinate nasal swabs were collected and tested using the Luminex Respiratory Pathogen Panel, which detected 16 viral pathogens. Viral infection was defined as one or more positive tests from the same virus or viral subtype within 30 days of previous positive. Maternal report and medical chart abstractions identified health care utilization.
Results: From 4/2017 to 7/2020, 245 mother-infant pairs were recruited and followed. From the 13,781 nasal swabs tested, a total of 2,211 viral infections were detected, of which, 821 (37%) were symptomatic. Children experienced 9.4 respiratory viral infections/child-year; half were rhinovirus/enterovirus. Viral ARI incidence was 3.3 episodes/child-year. Emergency department visits or hospitalization occurred with only 15% of respiratory syncytial virus infections, 10% of influenza infections, and only 4% of all viral infections. Regardless of pathogen, most infections were asymptomatic or mild.
Conclusions: Respiratory viral infections are common in children 0-2 years. Most viral infections are asymptomatic or non-medically attended, underscoring the importance of community-based cohort studies.
