Incidence of Medically Attended Acute Respiratory Illnesses Due to Respiratory Viruses Across the Life Course During the 2018/19 Influenza Season

Abstract

Consistent with other studies focused on single viruses, we found that influenza and RSV were major causes of acute respiratory illness in persons of all ages. In comparison, coronaviruses and rhinovirus were also important pathogens. Prior to the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), coronaviruses were the second-most common cause of medically attended ARI during the 2018/19 influenza season.
