How can Epstein-Barr infections, the primary cause of mononucleosis, be prevented?
It is nearly impossible to prevent Epstein-Barr infections, because most healthy people carry the virus and can pass it on to others. After the virus enters the body, the immune system begins to produce antibodies against it. The Epstein-Barr virus remains inactive in the body throughout life, but it may become active from time to time. However, reactivation of the virus does not result in clinical symptoms in individuals who have normal immune systems.
