Mononucleosis

Mononucleosis

Mononucleosis, or 'mono', is a common viral infection in college students. Epstein-Barr virus (EBV) is the most common cause of mononucleosis. Most people will be infected with EBV at some time in their lives. Mono frequently affects adolescents and young adults, especially when residing, studying, and socializing in crowded settings, such as a university. Mono can be spread through contact with saliva, including eating or drinking after an infected person, or through kissing a contagious person. In the past, mono was called “the kissing disease”, but kissing is only one way mono is spread. It is difficult to accurately determine when or from whom a person caught mono. It generally takes 4–8 weeks for the first symptoms to appear. Once someone has mono, they are likely to remain contagious for many weeks and may continue to be contagious intermittently for decades. Infection in early childhood is often asymptomatic or have only mild symptoms, which may go unnoticed at that age.
