I have had a sore throat for about a week and that has been my only symptom. I went to the doctor today and they said I had mono. But I have been around people for the past several weeks and no one has gotten sick. Also I haven't been around anyone with mono. I feel just fine other than a sore throat. I just want to know if I'm contagious really bad because I don't feel like not being able to do anything or see anybody for 2-4 weeks if I feel fine. And if I am contagious when should I not be contagious?
