Mononucleosis is a viral infection caused by either the Epstein-Barr virus or cytomegalovirus. It initially attacks epithelial tissue in the salivary gland and throat and then moves on to the B-cells and lymph nodes. Symptoms include fatigue, sore throat, fever and swollen lymph nodes. In some cases there may also be a swollen liver and enlarged spleen.
In the acute stages of mononucleosis massage is contraindicated. Non-circulatory types of massage may be appropriate in the recovery state. Abdominal work should be avoided.
