Abstract Influenza A(H1N1)pdm09 virus carrying an I38N substitution was detected in an untreated teenager in Japan . The I38N mutant virus exhibited reduced susceptibility to baloxavir but remained susceptible to neuraminidase inhibitors and showed reduced growth capability . Monitoring antiviral drug susceptibility of influenza viruses is necessary to aid public health planning and clinical recommendations.
