Background: Human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) are genetically related viruses and major causes of medically attended acute respiratory illness in children. Research comparing the severity of illnesses resulting from these infections lacks consensus.
Methods: Children younger than 18 years with acute respiratory illness were enrolled through active, prospective surveillance from 2016 to 2020 at 7 US pediatric hospitals and emergency departments (EDs).
Objective: To characterize the incidence of adverse events (AEs) associated with antibiotics used to treat acute otitis media in children.
Study Design: We searched MEDLINE for studies conducted between January 1, 1966, and August 25, 2018. Two authors independently assessed potential studies and extracted the data.
