Step-by-step explanation:
Epstein-Barr Virus (EBV) causes a disease called mononucleosis. It is also called a 'kissing disease' because the virus is most commonly passed through saliva.
It is the most known human herpes virus. Once infected, a person develops symptoms like of a mild cold, with a slight fever, fatigue, rash and the swelling of glands in the neck.
The virus is found in saliva, blood and semen. It can stay active in the body for months or even years without presenting any visible symptoms.
