EBV can establish life-long latent infection in host due to the balance between EBV and host immune system. (ijbs.com)

They also argue that it enhances lytic infections because of the inflammatory suppression. (phoenixrising.me)

Primary infection of adolescents and young adults often results in infectious mononucleosis with fever, lymphadenopathy, and sore throat ( 1 ). (frontiersin.org)
Some of these patients develop fulminant infectious mononucleosis and die within days or weeks of primary infection. (frontiersin.org)

The lymph nodes and spleen may be enlarged, so CMV should be included in the differential diagnoses of infections that produce lymphadenopathy. (medscape.com)

Symptoms, when apparent, develop 9-60 days after primary infection. (medscape.com)
The diagnosis of BKPyV-associated pneumonia was confirmed by metagenomic next-generation sequencing and polymerase chain reaction after the sudden worsening of the pulmonary infection signs and symptoms concomitant with renal dysfunction and systemic immune weakening. (biomedcentral.com)
11 ) Chronic symptoms for years after an Epstein Barr infection have been known. (transcendingsquare.com)

1 ). of VCA IgG and EBNA IgG in the infections according VCA IgM and EBV is a globally prevalent virus and absence of VCA IgM is typical of past VCA IgG positivity, and the presence or over 90% of the world's population is infection. (who.int)
