However, in the 2019– 20 season, the share of baloxavir and laninamivir was reduced to 3% and 17%, respectively, in contrast to an increase in the share of oseltamivir (66%). The total prescription of anti-influenza agents for patients decreased in the 2019– 20 season (205 patients), compared with the 2018– 19 season (509 patients).Conclusion: These results suggest significant changes such as a reduction in the prescription of anti-influenza agents, especially baloxavir, likely due to the suspected prevalence of a baloxavir-resistant strain of influenza virus and the emergence of SARS-CoV-2 in Japan.Keywords: anti-influenza agents, oseltamivir, laninamivir, zanamivir, peramivir, novel coronavirus-2019, COVID-19
