Graphical Overview of Infectious Diseases

　※The aggregated weekly number of cases reported in the National Surveillance System of Infectious Diseases is used. The latest data for epidemiological week 47 are as of November 26, 2025, and data from previous weeks have been republished.
　※The shaded area shows the baseline range. The lower bound is the five-year average for each epidemiological week computed over a centered 7-week window, and the upper bound is the same average plus 2 SD. Both bounds were subsequently smoothed using a moving-average filter. In the COVID-19 figure, the gray trace represents the prior year.
