claim: high temperature and high humidity increase the transmission of covid-19
evidence_1: if assuming a 30 degree and 25 percent > increase in temperature and relative humidity from winter to summer in the > northern hemisphere, we expect the r values to decline about 0.89 (0.69 by > temperature and 0.20 by humidity).", "we find a similar influence of the temperature > and relative humidity on effective reproductive number (r values) of > covid-19 for both china and the u.s. before lockdown in both countries: one- > degree celsius increase in temperature reduces r value by about 0.023 (0.026 > (95% ci [-0.0395,-0.0125]) in china and 0.020 (95% ci [-0.0311, -0.0096]) in > the u.s.), and one percent relative humidity rise reduces r value by 0.0078 > (0.0076 (95% ci [-0.0108,-0.0045]) in china and 0.0080 (95% ci > [-0.0150,-0.0010]) in the u.s.)."
