Mononucleosis, or “mono” for short, is a viral illness that is almost always transmitted through saliva and affects mainly teenagers and young adults.

While the symptoms of mono can last for months in some cases, this viral infection isn’t usually thought of as a serious illness. Continue reading to learn more about mono from our AFC Urgent Care Hickory team.

What Is Mono?

Mono is a set of symptoms that can be caused by a variety of viruses, but the Epstein-Barr virus (EBV) is the most common culprit. According to experts, by the age of 35, about 90% of people will have had mono; however, many will simply be carriers of the virus rather than experiencing symptoms. While symptoms aren’t usually severe, they can become severe in rare cases.

Many people who contract the virus will have mono symptoms, which we’ve mentioned below.

Common Mono Symptoms

• Extreme fatigue
• Fever
• Sore throat
• Head and body aches
• Swollen lymph nodes in the neck and armpits
• Swollen liver or spleen or both
• Rash

Is Mono a Cause for Serious Concern?

Normally, no. Most mono cases get better in about a month, but there are many cases where feelings of extreme fatigue last for up to six months, or even longer.

However, if a case of mono were to turn severe, a ruptured spleen is one of the most serious complications that could occur. Mono can cause an enlarged spleen, which could burst, thus causing internal bleeding in the abdomen. If your teenage or young adult child is experiencing mono, don’t hesitate to call your doctor if he or she experiences any of the symptoms we’ve listed below.

When to Call a Doctor

• Difficulty breathing or swallowing
• Dizziness or fainting
• Extreme muscle weakness in arms or legs
• Intense body aches
• High fever that won’t go away
• Severe headaches
• Sharp pain in the upper left abdomen
