The National Center for Disease Control published the recommendations for safe behavior at holiday gatherings. According to the NCDC, festive gatherings are not recommended in connection with the Covid-19 pandemic. Those who plan to visit should follow the following safety rules:
Do not use common/ceremonial wares for dinner; if other than your family members are present at the holiday gatherings, be sure to wear a facemask.
Remove the mask while eating only and keep at least a meter distance from those around.
Wash your hands before and after eating and follow the respiratory etiquette.
