When you may have a respiratory virus... Stay home and away from others (including people you live with who are not sick) if you have respiratory virus symptoms that aren't better explained by another cause. These symptoms can include fever, chills, fatigue, cough, runny nose, and headache, among others.* You can go back to your normal activities when, for at least 24 hours, both are true: Your symptoms are getting better overall, and You have not had a fever (and are not using fever-reducing medication).
