利用日本所有47个都道府县的每周流感病例数据以及1999年至2018年日本职业棒球联盟（NPB）的数据，我们研究了举办比赛对当地流感传播的影响。结果强调，在流感季节，对于在其主场球场举行的每一场NPB比赛，从那一周到下一周，每个哨点医疗机构（SMI）的病例平均增加0.18例。该效应对不同质量标准和安慰剂试验具有稳健性。这意味着在NPB和流感季节重叠期间，病例数增加了约0.1%。
Using weekly-level influenza case data from all 47 prefectures in Japan alongside data from Nippon Professional Baseball (NPB) league from 1999 to 2018, we examine the effect of hosting games on local influenza transmission. The results highlight that during the flu season, for every NPB game held at its home ballpark, there is an average increase of 0.18 cases per sentinel medical institution (SMI) between that week and the following week. The effects are robust to different specifications and placebo tests. This translates to about a 0.1% increase in the number of cases during the overlap of NPB and flu seasons.
