A majority of the population is infected with EBV at sometime during their lives with an estimated 90%-95% of adults demonstrating seropositivity by 21 years of age. Therefore, even individuals exposed to infected contacts have shown to be previously infected with EBV and hence are not at risk for the manifestation of<unk> . However, once infected, the patient carries the virus for the rest of their life with the virus typically residing dormantly in the B lymphocytes. Independent infections of<unk>  may be contracted multiple times, regardless of whether the patient is already carrying the virus dormantly. Periodic reactivation of the virus may occur, during which time the patient is again infectious, but usually without any symptoms of illness. Therefore, in susceptible hosts under the appropriate environmental stressors, reactivation of the virus occurs to cause vague subclinical symptoms or remain mostly asymptomatic and diagnosed only by a positive serologic response. However, its imperative to note that during this phase the virus can spread to others.
