A novel coronavirus infection [coronavirus disease 2019 (COVID-19)] became a global epidemic just months after the first case of infection was reported in Wuhan, China in December 2019. Its spread has severely affected social systems and people's lives. In the academic world, this led to an increase in the number of papers submitted to this journal. While the number of articles submitted to the journal reached a record high in 2020, the number of articles submitted last year returned to prepandemic levels. In this article, we report on the current submission conditions, including the number of submissions and acceptance rate, as well as the citation trends of highly cited articles and those published by the journal in 2022.
