More than 87,000 scientific articles on COVID-19 were published between the start of the pandemic and October of 2020 (https://news.osu.edu/more-than-87000-scientific-papers-on-coronavirus-since-pandemic/). More than 720,000 unique authors have contributed to COVID-19 articles as of August, 2021 (https://royalsocietypublishing.org/doi/10.1098/rsos.210389 ).
Having an article which was published in the Optimal Data Analysis journal cited by the World Health Organization (WHO), in their 2021 and 2022 COVID-19 guidelines, is a tremendous honor.
