What Is Kissing Disease?
5. Signs & Symptoms
Infectious mono is a slow-moving illness. It can take up to six weeks between contracting the virus and the appearance of the first signs. In addition, when the symptoms do begin, they can start slowly. They do not necessarily occur simultaneously.
Extreme fatigue, sore throat, fever and swollen lymph nodes under the arms and at the back of the neck are common symptoms of the illness. A persistent headache is not unusual. It is also possible to have swollen tonsils and spleen as well as a skin rash.
