Detection of a Transient R292K Mutation in Influenza A/H3N2 Viruses Shed for Several Weeks by an Immunocompromised Patient: TABLE 1

Abstract

We describe the case of an immunocompromised patient, positive for influenza A virus (H3N2), in whom the neuraminidase R292K mutation was transiently detected during oseltamivir treatment. The R292K mutation was identified by direct testing in 3 of 11 respiratory specimens collected throughout the patient's illness but in none of the cultures from those specimens.
