The coronavirus (COVID-19) epidemic reported for the first time in Wuhan, China at the end of 2019, which has caused 4648 deaths in China as of July 10, 2020. This study explored the temporal correlation between the case fatality rate (CFR) of COVID-19 and particulate matter (PM) in Wuhan. We conducted a time series analysis to examine the temporal day-by-day associations. We observed a higher CFR of COVID-19 with increasing concentrations of inhalable particulate matter (PM) with an aerodynamic diameter of 10 μm or less (PM) and fine PM with an aerodynamic diameter of 2.5 μm or less (PM) in the temporal scale. This association may affect patients with mild to severe disease progression and affect their prognosis.
截至 2020 年 7 月 10 日，中国报告的首例新型冠状病毒（COVID-19）疫情于 2019 年底在中国武汉爆发，已造成中国 4648 人死亡。本研究旨在探讨 COVID-19 的病死率（CFR）与武汉地区颗粒物（PM）之间的时间相关性。我们进行了时间序列分析，以检验逐日的时间关联。我们发现，随着可吸入颗粒物（PM）浓度的增加，COVID-19 的 CFR 也随之升高，PM 浓度的上限为 10μm，PM 浓度的上限为 2.5μm。这种关联可能会影响从轻症到重症的疾病进展，并影响其预后。
