Seasonality of COVID-19: Impact on the spread and severity

15 April 2020

This rapid report synthesises the evidence base on the impact of winter on the spread of COVID-19. Research suggests there will be some influence of winter on the spread and severity of COVID-19, as lower humidity and air temperature can increase the viability and virulence of the virus and therefore its infectivity. However, human behaviour is a dominant contributor to the transmission of COVID-19 and physical distancing will have a more potent impact on controlling the spread than seasonal variability.
