The purpose of this study is to analyze the recent incidence rates of Behçet's disease using big data. Big data for this study was used for academic purposes in the 2019 to 2022 rare disease patient statistics from the Korea Disease Control and Prevention Agency (public domain source). A total of 3,886 newly diagnosed patients with Behçet's disease in Koreans from 2019 to 2022 were analyzed. In this study, the incidence of Behçet's disease was analyzed according to gender and age, and the incidence in the total population was also analyzed. The incidence rates of Behçet's disease from 2019 to 2022 were compared and analyzed at 1-year intervals. The incidence rate in men was in the 30% range, and in women, it was in the 60% range. The incidence of Behçet's disease in individuals over their 50s, approaching the elderly age group, was 42%. In the younger age group under 30, it was 16%. In this study, when analyzing the 4-year average incidence of Behçet's disease by age group from 2019 to 2022, it was found to be most common in people in their 40s at 24% over the past four years, followed by 50s at 22%, 30s at 17%, 60s at 14%, 20s at 12%, and 10s and 70s at 3%, showing a wide age distribution. This suggests that Behçet's disease can occur at any age.
