GENERAL HISTOLOGY

Detailed explanation-1: -What is infectious mononucleosis? Infectious mononucleosis is characterized by swollen lymph glands, fever, sore throat, and extreme fatigue. It’s often spread through contact with infected saliva from the mouth. Symptoms can take between 4 to 6 weeks to appear and usually do not last beyond 4 months.

Detailed explanation-2: -Infectious mononucleosis is a clinical entity characterized by pharyngitis, cervical lymph node enlargement, fatigue and fever, which results most often from a primary Epstein–Barr virus (EBV) infection.

Detailed explanation-3: -Epstein-Barr virus, or EBV, is one of the most common human viruses in the world. It spreads primarily through saliva. EBV can cause infectious mononucleosis, also called mono, and other illnesses. Most people will get infected with EBV in their lifetime and will not have any symptoms.

Detailed explanation-4: -If you have mono, you may have a high level of a type of white blood cell called a lymphocyte in your blood. Your immune system also will make certain types of antibodies (heterophile antibodies) to fight off the EBV. These antibodies will also appear in your blood if you have mono.
