It's treated as a common cold now. You can follow the government health guidelines for covid. They are telling people to stay home and if you go out wear a mask. Please wear it correctly. Even well after covid years people still disrespectfully improperly wear them or do other disrespectful things like lower it when they cough or think their nose hanging out of it protects them. If you are affected badly by colds you can get a dr note disabling you for a week. You don't have to wear a mask while sick but please, please do.
