What is the most common way to get mono?

The most common way to contract mononucleosis, often referred to as "mono," is through the exchange of saliva, which is why it is sometimes called the "kissing disease." This can occur through kissing, sharing drinks, or using the same utensils as someone who is infected. The Epstein-Barr virus (EBV), which causes mono, can also be spread through other bodily fluids, but saliva is the primary route of transmission.
