  Fig. 1 Change in age-group composition of varicella cases in Korea during 2010-2019 with a significant reduction in the annual total number of varicella cases. Three-year (2010, 2014, and 2019) data from the Korea National Health Insurance Service were used. The proportion of the 25+ years old group in each year was very small (≤ 0.5%) and not presented here for simplicity.
