Viral lineage composition at the SBCVIC and GISAID entries during the seventh wave, and the concurrent COVID-19 prevalence in Japan. (A) A stacked bar graph illustrates the frequency distribution of viral lineages at the SBCVIC (left) and GISAID entries (right), whereas a line graph represents the number of cases reported in NESID during the corresponding period. (B) The number of cases for each viral lineage at the SBCVIC (left) and GISAID entries (right) are shown as stacked bar graphs. Concurrently, a line graph indicates the number of cases reported in NESID during the same period. NESID, The National Epidemiological Surveillance of Infectious Diseases.
