Individual and Environmental Risk Factors for COVID-19 Mortality in Elderly in 7 European University Hospitals

Because the elderly account for 80% of deaths from COVID-19 and they may be more vulnerable to air pollution, in this retrospective study we aimed to explore individual and environmental risk factors for COVID-19 mortality in the geriatric departments of seven European University hospitals, between February and May 2020.Long-term exposure to air pollution was estimated through annual pollutant concentrations at the residential address over the last two years.Short-term variations in air pollutants and weather parameters *T.Bourdrel and L. Zabrocki contributed equally to this work.
