Temperature, Humidity, and Latitude Analysis to Estimate Potential Spread and Seasonality of Coronavirus Disease 2019 (COVID-19)

  • Sajadi et al. found that 8 cities with substantial community spread of COVID-19 were located along a restricted latitude across different continents, and had consistently similar weather patterns characterized by mean temperature between 5-11°C and low humidity, compared with 42 cities without such spread. This is consistent with the behavior of a seasonal respiratory virus, and points to weather modeling as a possible predictor of high risk of community spread in space and time.
