Coronavirus (COVID-19) Collection
- Since December 2019, COVID-19 caused by SARS-CoV-2 has spread worldwide (Hayakawa et al., 2020). As of January 25th, 2022, 544 re-infected COVID-19 cases have been reported worldwide (BNO news. 2022; Inada et al., 2021).
- The COVID-19 outbreak in China at the end of 2019 had spread to Japan by early 2020. The surge in infected cases may have precipitated behavioral changes among physicians and patients, including increased unnecessary antimicrobial use (AU) that could promote antimicrobial resistance (AMR).
