Using an influenza epidemic threshold different from those in the United States and Europe caused longer epidemic periods in Korea during the 2018–2019, 2019–2020, and 2022–2023 seasons: a comparative study

Dataset 1. Research data used to draw Fig. 1, which shows seasonal influenza activity during the 2018−2019 season in Korea according to different influenza epidemic thresholds in Korea, the United States, and Europe. Dataset 2. Research data used to draw Fig. 2, which shows seasonal influenza activity during the 2019−2020 season in Korea according to different influenza epidemic thresholds in Korea, the United States, and Europe. Dataset 3. Research data used to draw Fig. 3, which shows seasonal influenza activity during the 2022−2023 season in Korea according to different influenza epidemic thresholds in Korea, the United States, and Europe.数据集1：用于绘制图1的研究数据，该图展示了2018—2019流感季韩国的季节性流感活动水平，其绘制依据为韩国、美国及欧洲三地不同的流感流行阈值（influenza epidemic thresholds）。数据集2：用于绘制图2的研究数据，该图展示了2019—2020流感季韩国的季节性流感活动水平，其绘制依据为韩国、美国及欧洲三地不同的流感流行阈值。数据集3：用于绘制图3的研究数据，该图展示了2022—2023流感季韩国的季节性流感活动水平，其绘制依据为韩国、美国及欧洲三地不同的流感流行阈值。
