VIRUS, RECURRENCE, INFLUENZA
In this pooled analysis, favorable safety and effectiveness of single-dose baloxavir were observed in influenza virus-infected children across all age groups. Fever recurrence and transient increases in influenza virus titer were observed in children < 6 years. In our study, baloxavir-treated children recovered without prolongation of influenza symptoms regardless of age, transient influenza virus titer increase, PA/I38X virus detection, or co-infection.
