    viral infection often called "mono" spread through saliva

    Infectious mononucleosis, often referred to as "mono" or the "kissing disease," is a viral infection typically caused by the Epstein-Barr virus (EBV). It is characterized by symptoms such as fever, sore throat, swollen lymph nodes, and fatigue. The virus is primarily spread through saliva, which is why it is commonly associated with kissing, but it can also be transmitted through other forms of close contact.
