Cmv is a virus that is closely related to mononucleosis (or ebv).
It is commonly found in most humans. Most people actually experience the virus and never know they had it. However, some do feel the symptoms. Since it is a virus, antibiotics will not work. You will have to let it run its course.
Once you have had the disease, the virus lies dormant in your body. Most people do not suffer a recurrence, unless you have a seriously comprimised immune system.
I am assuming that you have been to the doctor. If you are showing symptoms, you may want to look into why...Stress, anemia, other ways of lowering your immune system may be to blame.
Hope this helps!
