Mono is a very common infection and pretty much anyone is a risk of getting it. If you are above the age of 30, there is a good chance that your body already has antibodies against the mononucleosis virus. More than 95% of adults between the ages of 35 and 40 have been previously exposed to the virus, and have created antibodies to it. The older you are, the less chance you have of getting mono - 70 year olds have less than a 1% chance of developing the infection.

Teenagers and young adults between the ages of 15 and 25 are at the greatest risk, but children can also get mild forms of mono. You are especially at risk if you:

• Live in a dormitory or military barracks
• Share food, drinks, and utensils with others
• Frequently kiss others
• Have close contact with an infected person
