Air Pollution and Respiratory Infectious Diseases
研究美国空气质量指数与每周新冠和流感样病例的关系，使用大气逆温作为工具变量，发现空气污染与这两种疾病无显著关联。
Abstract Recent research suggests that short-term exposure to air pollution is associated with an elevated prevalence of respiratory infectious disease. In this paper, we examine the relationship between the air quality index and weekly cases of COVID-19 and influenza-like illnesses (ILI) in the United States. We address potential bias from omitted variables and measurement error with an instrumental variable approach using atmospheric temperature inversions. Unlike other recent studies, we find no relationship between air quality and either COVID-19 or ILI cases.
