Humidity is a consistent climatic factor contributing to SARS‐CoV‐2 transmission – Ward – – Transboundary and Emerging Diseases – Wiley Online Library

“Increased relative humidity was associated with decreased cases in both epidemic phases, and a consistent negative relationship was found between relative humidity and cases. Overall, a decrease in relative humidity of 1% was associated with an increase in cases of 7–8%. Overall, we found no relationship with between cases and temperature, rainfall or wind speed. Information generated in this study confirms humidity as a driver of SARS‐CoV‐2 transmission.”
