As many people begin to plan for fall and winter holiday celebrations, the CDC offers considerations to help protect individuals and their families, friends, and communities from COVID-19. These considerations are meant to supplement—not replace—any state, local, territorial, or tribal health and safety laws, rules, and regulations with which holiday gatherings must comply. When planning to host a holiday celebration, you should assess current COVID-19 levels in your community to determine whether to postpone, cancel, or limit the number of attendees.
To see the list of considerations for before, during and after the celebration, including high, moderate and low risk activities for Halloween, go to the following website. https://www.cdc.gov/coronavirus/2019-ncov/daily-life-coping/holidays.html#halloween
