ABSTRACT
OBJECTIVE:
To estimate the association between weather and COVID-19 fatality rates during US stay-at-home orders.METHODS:
With a county-level longitudinal design, this study analyzed COVID-19 deaths from public health departments' daily reports and considered exposure as the 18 to 22 day-period before death. Models included state-level social distancing measures, Census Bureau demographics, daily weather information, and daily air pollution. The primary measures included minimum and maximum daily temperature, precipitation, ozone concentration, PM2.5 concentrations, and U.V. light index.RESULTS:
A 1â°F increase in the minimum temperature was associated with 1.9% (95% CI, 0.2% to 3.6%) increase in deaths 20âdays later. An ozone concentration increase of 1âppb (part per billion) decreased daily deaths by 2.0% (95% CI, 0.1% to 3.6%); ozone levels below 38âppb negatively correlated with deaths.CONCLUSIONS:
Increased mobility may drive the observed association of minimum daily temperature on COVID-19 deaths.
