The increased uncertainty caused by a sudden epidemic disease has had an impact on the global financial market. We aimed to assess the primary healthcare system of universal health coverage (UHC) during the coronavirus disease (COVID-19) pandemic and its relationship with the financial market. To this end, we employed the abnormal returns of 68 countries from January 2, 2019, to December 31, 2020, to test the impact of the COVID-19 outbreak on abnormal returns in the stock market and determine how a country's UHC changes the impact of a sudden pandemic on abnormal returns. Our findings show that the sudden onset of an epidemic disease results in unevenly distributed medical system resources, consequently diminishing the impact of UHC on abnormal returns.
突发传染病引起的不确定性增加对全球金融市场产生了影响。我们旨在评估在冠状病毒病（COVID-19）大流行期间全民医保（UHC）的初级卫生保健系统及其与金融市场的关系。为此，我们采用了 2019 年 1 月 2 日至 2020 年 12 月 31 日期间 68 个国家的异常收益率，以检验 COVID-19 爆发对股票市场异常收益率的影响，并确定一个国家的 UHC 如何改变突发大流行对异常收益率的影响。我们的研究结果表明，传染病的突然爆发导致医疗系统资源分配不均，从而降低了 UHC 对异常收益率的影响。
