Currently vulnerable age groups in most countries are affected by the respiratory -coronavirus disease 2019 (COVID-19). Long-term-exposure to high levels of PM2.5 (particulate matter with aerodynamic diameter ≤ 2.5μm) is also associated positively with repository deaths. The aim of this study is to find if high PM2.5 levels affect COVID-19 caused deaths in Japan. COVID-19 caused death and tested positive cases in all prefectures during the study period from Feb. 18 up to Apr. 16, 2020 are analyzed. PM2.5 caused deaths from 2010 to 2017 are calculated based on PM2.5-relative risk (RR) of 1.04 (95% CI: 1.01 – 1.08) from the World Health Organization-Air Quality Guidelines (WHO–AQG). The findings of this study show that old people who are living in prefectures with high levels of PM2.5 are the most vulnerable to COVID-19. The estimated death cases from 2010 to 2017 are about 115,532 (95% CI: 28,883 - 231,064) cases. Thus; policy decision makers could consider PM2.5 data to support their efforts not only to minimize the spread of COVID-19, but also to improve air quality.
