Infectious mononucleosis.

EBV-induced IM is a generally self-limited infection characterized by fever, pharyngitis, and adenopathy. Management consists of basic supportive measures and treatment of streptococcal pharyngitis when present. Corticosteroids may be considered for individuals who exhibit evidence of significant upper airway obstruction. To date there is little evidence to support the use of antiviral agents in immunocompetent patients. Complications of IM may arise, which can be life-threatening, but these are relatively rare.
