The coexistence of hepatitis A and infectious mononucleosis.

Hepatitis A is an acute, self-limited disease that spreads predominantly by the fecal-oral route. Hepatitis A characteristically has an acute, sudden influenza-like onset with a prominence of myalgia, headache, fever and malaise. Infectious mononucleosis is an acute illness characterized clinically by sore throat, fever and lymphadenopathy. The virus usually spreads from person to person by close contact with nasopharyngeal secretions. In this case the coexistence of both diseases in the same patient is found interesting.
