How do people get mono?
Mono is not spread as easily as some other viruses, such as the common cold. The mono virus is found in saliva and mucus. It is usually passed from one person to another through kissing, which is why it is often called the kissing disease. However, mono can also be passed through exposure to a cough, sneeze or through sharing food utensils (such as drinking glasses, spoons and forks) with someone who has mono. Signs of mono usually develop 4 to 6 weeks after you're exposed to the virus. Generally, people only get mono once. It's most common among people 15 to 35 years of age.
