Children with mono may have any combination of symptoms or very few symptoms, according to KidsHealth. Although symptoms typically go away in two to four weeks, in older teens, fatigue and weakness can carry on for months after the initial illness. Blood tests are typically used to confirm the diagnosis of mono, as well as examination in which swollen tonsils and an enlarged liver and spleen can also indicate the illness.

Children involved in sports are typically recommended to avoid exercise for one month following the illness to decrease the chances of complications from an enlarged spleen, according to KidsHealth. Kids typically recover on their own without complication. However, in some cases, complications such as anemia, meningitis or inflammation of the heart can occur. Washing hands often and avoiding sharing drinks and utensils with others are the only ways to prevent the spread of mono to others.
