What Is Mono?
2. Causes
Mono is usually caused by the Epstein-Barr virus. The virus is often spread when items like cutlery and crockery are shared. It is often found in saliva, so it is sometimes contracted after kissing an infected person. This is how the disease got another name it is commonly known by: The kissing disease.
Young adults are more likely to catch the disease as they begin having intimate relationships with other people, but it can affect older adults as well. The main reason that it doesn’t usually affect older adults is that their immune systems have built strong defenses against the disease due to more exposure to it than younger people.
