During the first 1-2 weeks after experiencing symptoms of mono you are contagious. Also, during the time you feel sick -- which is typically 1-2 weeks, but for some people can be more -- you are contagious. After you have mono you continue to have the virus in your body for the rest of your life. There are only rare occasions where you actually get the symptoms again. However, contrary to popular belief, mono is not very contagious. Yes, it is known as "the kissing disease," but a peck will not spread it; it requires more of a deep, open mouth kiss to contract it; you can also contract it from sharing food and/or drinks with carriers of the virus. I thought it would be helpful, I had mono June '07 and i spread it to my boyfriend who never had it August '09. So anyone who hasn't had it is able to catch it.

Can someone with mono be contagious while on antibiotics?

The question is irrelevant: the disease of mononucleosis is caused by a virus, not a bacterium. Thus, antibiotics have absolutely no effect on the Epstein-Barr virus, which causes mononucleosis.I will ignore the last part of your question, and answer the main section, asking if mononucleosis is contagious. The short answer is yes, more or less. But there is a longer, more detailed, answer.As soon as the person is exposed to the Epstein-Barr virus, they are contagious. They remain contagious through the incubation period and the time the person shows symptoms. After the symptoms go away, the virus resides in the body harmlessly. but it is still contagious. As time passes, it becomes less contagious, and by eighteen months after symptoms disappear, it will be highly unlikely the disease will be transmitted.Sources were the web link as follows:
