Infectious Mononucleosis

Infectious Mononucleosis also known as the triad of fever, tonsillar pharyngitis (sore throat), and lymphadenopathy (enlarged lymph nodes)


Acute illness due to epstein barr virus (EBV), usually occurring in young adults and adolescents


Symptoms include fever, lymphadenopathy (swollen lymph nodes, splenomegaly (enlarged spleen), palatal petechiae (red spots in the mouth) rash, URI (fatigue, sore throat, cough, sneeze, headache), decreased appetite, and subclinical hepatitis.


Complications may include splenic rupture and airway obstruction


Labs in someone with infectious mononucleosis may indicate elevated white blood cell count, atypical lymphocytes, elevated liver function. CBC should be done along with a heterophile test (monospot test). EBV-specific antibodies can also be tested for a more definitive test


The treatment is based on symptoms. Pain relievers or anti-inflammatories may be helpful for symptoms if impending airway obstruction→ er and steroids avoid contact sports for 4 weeks after symptom onset


If diagnoses you should avoid person to person contact, sexual contact or breastfeeding to prevent spread. Kissing is the most common route of spread in the adolescent and young adult population
