What condition is caused by the Epstein-Barr virus?

The condition caused by the Epstein-Barr virus is infectious mononucleosis. This virus, part of the herpesvirus family, is known for its role in causing this illness, which often presents with symptoms such as fatigue, fever, sore throat, and swollen lymph nodes. The virus is commonly transmitted through saliva, which is why it is often referred to as the "kissing disease."

Infectious mononucleosis specifically involves the activation of the immune response and a significant increase in lymphocytes, which can lead to the characteristic symptoms. Other diseases mentioned, such as chickenpox, shingles, and measles, are caused by different viruses altogether and do not involve the Epstein-Barr virus. Understanding these viral infections and their causative agents is essential for identifying and managing the corresponding diseases effectively.
