Immune System
- Splenomegaly
Symptomatic individuals typically first experience fever, malaise, and fatigue, which is later accompanied by acute pharyngitis, tonsillitis, lymphadenopathy, and/or splenomegaly lasting up to a month. [amboss.com]
The diagnosis of IM was confirmed by the demonstration of high serum titers of antibodies against Epstein-Barr virus, IgM class (4 patients) or heterophil antibodies (1 patient), plus peripheral lymph node enlargement (3 patients), splenomegaly (4 patients [repositorio.uchile.cl]
The diagnosis is suggested by the presence of a lymphocytosis and/or splenomegaly. The majority of patients do not have infectious mononucleosis. [scienceopen.com]

EBV is rather uncommonly confirmed as an etiologic agent of acute hepatitis in adults. [ncbi.nlm.nih.gov]
IMPORTANT POINTS The etiologic agent for infectious mononucleosis is Epstein-Barr virus, although a mononucleosis-like syndrome can be caused by other viral agents, most notably cytomegalovirus. [pedsinreview.aappublications.org]

Can You Prevent It? There’s no vaccine to prevent mono. EBV can stay in your saliva for months after you’re infected, so even if you don’t have symptoms or feel sick, you may be able to spread it. This makes it hard to prevent the spread of mono. [webmd.com]
Is it possible to prevent mono? Since mono is spread from person to person, avoiding close personal contact with infected individuals and practicing excellent hygienic practices can help prevent transmission of the virus. [medicinenet.com]
