Review: Temperature, humidity, and latitude analysis to estimate potential spread and seasonality of coronavirus disease 2019 (COVID-19)
The cohort study modeled data from 50 different cities and found that SARS-CoV-2 appears to behave like a seasonal respiratory virus.
- 8 cities w/ substantial spread of COVID-19 were compared with 42 cities that have not been affected or did not have substantial community spread.
- Data were collected from January to March 10, 2020.
- The main outcomes was substantial community transmission was defined as at least 10 reported deaths in a country as of March 10, 2020.
- The 8 cities with substantial community spread (as of the end of data collection period), were located roughly on the 30° N to 50° N corridor. They had consistently similar weather patterns, consisting of mean temperatures of between 5 and 11 °C, combined with low humidity.
- The distribution of substantial community outbreaks of COVID-19 along restricted latitude, temperature, and humidity measurements was consistent with the behavior of a seasonal respiratory virus.
