Description
Mononucleosis is a viral infection most commonly caused by the Epstein-Barr virus. It has traditionally been known as the “kissing disease,” as it is easily spread among teens and young adults through saliva and other bodily fluids. Common symptoms include fever, fatigue, swollen lymph nodes, and sore throat, usually lasting 1 to 4 weeks. To confirm infectious mononucleosis, doctors perform a blood test and look at the number and shape of the lymphocytes in the blood.
This slide shows blood cells of someone with mononucleosis. You can easily see the variable shape and size of the lymphocytes and their nuclei as you explore this slide. Stained with Wright’s stain.
