The virus is not able to travel as far in humidity. Instead of 10 feet it might be 3 feet.
Exactly. From the abstract - “ One degree Celsius increase in temperature and one percent increase in relative humidity lower R by 0.0383 and 0.0224, respectively. This result is consistent with the fact that the high temperature and high humidity significantly reduce the transmission of influenza. It indicates that the arrival of summer and rainy season in the northern hemisphere can effectively reduce the transmission of the COVID-19.”
Fomites are probably a much larger factor than the droplets.
