In infectious mononucleosis, which activity should be avoided for several weeks due to splenic risk?

• A. Swimming
• B. Running
• C. Contact sports
• D. Reading

Answer: (C)

Infectious mononucleosis often causes splenomegaly, making the spleen more vulnerable to injury from blunt trauma. Because splenic rupture is a serious complication, activities that involve direct contact or collisions should be avoided for several weeks until the spleen returns toward normal size. That’s why avoiding contact sports is emphasized. Other activities like reading pose no splenic risk, and while swimming or running might be restricted if there’s significant splenomegaly, they aren’t inherently as high-risk as contact sports for splenic injury. If you notice sudden left upper quadrant pain, referred shoulder pain, dizziness, or signs of shock, seek urgent care.
