 [ Symptoms ] is my daughter is viral pharyngitis contagious  asking this for my daughter i do not want her to get anyone in our family sick especially if my daughter has to go to school she is also in choir should i write a note to her teacher letting her know if she has to rest her voice should i keep her home [ Disease ] most helpful answer viral pharyngitis is just a sore throat caused by a cold respiratory virus biologically respiratory viruses are contagious a day before you know you are sick and then for about two days later estimate exposing others would not likely cause them to have identical symptoms but they could get a cold since cold viruses are everywhere she can really go back to her usual activities school church choir when she is feeling better colds last about a week but most people feel fine by day four resting the voice when she has a sore throat is usually a good idea so use your own judgment
