claim: sunlight ultraviolet radiation dose is positively correlated with the percent positive of sars-cov-2 and four other common human coronaviruses in the u.s.
evidence_1: the weekly percent positive of sars-cov-2 during april 17, 2020 to july 10, 2020 showed a significant negative correlation with the sunlight uv radiation dose in census regions 1 and 2 of the u.s. while no statistical significance in the other regions.", "uvc can inactivate coronaviruses, including severe acute respiratory syndrome-coronavirus-2 (sars-cov-2).", "additionally, sunlight uv radiation also showed some negative effects with respect to the early sars-cov-2 transmission.", "in this study, spearman and kendall rank correlation analysis tests were used to analyze the correlation between the average percent positive of five human coronaviruses (sars-cov-2, covhku1, covnl63, covoc43, and cov229e) in the u.s. and the corresponding sunlight uv radiation dose the results indicated that the monthly average percent positive of four common coronaviruses was significantly negatively correlated with the sunlight uv radiation dose."
