COVID-19 infection spreads when people exhale droplets and particles containing the virus. They do this when speaking, coughing, exercising, sneezing and singing. These droplets and particles can hang in the air and when inhaled by others can result in infection.
But, outdoor settings make it easier and more likely to disperse the droplets and particles containing the coronavirus. This is largely due to airflow and meteorological conditions that essentially breakup the cloud of droplets and particles.
However, research indicates that it’s still possible to be transmit COVID-19 in outdoor settings—especially during times of high community spread. Masks can help lower the risk of getting COVID-19 both indoors and outdoors.
When COVID-19 spreads in a community, gathering outdoors significantly lowers the disease’s risk.
The key when gathering outdoors is to avoid prolonged, close, interpersonal contact with others (otherwise known as social distancing).
When community spread is high, even folks engaging in outdoor activities with others should consider wearing masks.
