The symptoms of infectious mononucleosis may include sore throat,fatigue of more than a few days duration, enlarged lymph nodes, fever, rash, headache, or jaundice. The disease usually also affects the spleen and liver.
Diagnosis is confirmed by blood test.
It is not very contagious, but may be transmitted by close personal contact such as kissing or by sharing eating utensils with a carrier, someone who is not sick but who harbors the causative agent. In most cases by the time active symptoms appear the disease is no longer contagious. Mono is not caused by fatigue. There is no specific medication to cure mono or shorten its course, but medication may be used to ease symptoms. The disease is self limited, usually runs its course in one to four weeks,and has no aftereffects.
