Infectious mononucleosis presenting as postpartum fever.

Infectious Mononucleosis and pregnancy are common conditions seen by obstetricians and family physicians. However, infectious mononucleosis in the postpartum period has not been reported in the literature. A 20 year-old woman presented with a four-day history of fever of 40 degrees C, and chills at her six-week postpartum visit, which prompted an evaluation of the cause of the fever. The atypical presentation of mononucleosis in this patient delayed the eventual diagnosis. Although Infectious Mononucleosis has not been mentioned in the literature as a cause of postpartum fever, it is likely more common than realized. For that reason the evaluation of Infectious Mononucleosis and postpartum fever are discussed.
