This includes everyone present, including hosts and guests.  Remember, the smaller the number of people, the safer. The host should collect names of all attendees and contact information in case contact tracing is needed later. Gather Outdoors  Keep it short Gatherings should be two hours or less.  The longer the duration, the risk of transmission increases. Rules for Singing, Chanting, and Shouting at Outdoor Gatherings Singing, chanting, shouting, and physical exertion significantly increases the risk of COVID-19 transmission because these activities increase the release of respiratory droplets and fine aerosols into the air. Because of this, singing, chanting, and shouting are strongly discouraged, but if they occur, the following rules and recommendations apply: All people who are singing or chanting should wear a face covering at all times while singing or chanting, including anyone who is leading a song or chant. Because these activities pose a very high risk of COVID-19 transmission, face coverings are essential to reduce the spread of respiratory droplets and fine aerosols; People who are singing, shouting, chanting, or exercising are strongly encouraged to maintain physical distancing beyond 6 feet to further reduce risk. People who are singing or chanting are strongly encouraged to do so quietly (at or below the volume of a normal speaking voice).
