Question
If a child experiences high fever symptoms and is diagnosed with infectious mononucleosis by a doctor, does high fever necessarily indicate the presence of this condition?
Answer
Infectious mononucleosis is caused by a virus entering the bloodstream, leading to toxicosis and subsequently damaging various tissues and organs of the lymphatic system. During the acute phase, B lymphocytes are often the first to be attacked due to the presence of the EB virus receptor (CD21) on their surface. In the acute phase, one in every 100 B lymphocytes is infected with the virus, while in the recovery phase, only one in every million B lymphocytes is infected. In the control of infection, cellular immunity may play a more important role than humoral immunity. It is recommended that patients should rest more and maintain a light diet.
