Frequently Asked Questions
Common questions about this quiz, what it covers, and what your results mean.
This quiz is for health education only and does not diagnose mononucleosis or any other condition. Seek medical care promptly for severe symptoms, worsening illness, trouble breathing or swallowing, dizziness, or sharp upper-left abdominal pain.
Mononucleosis, often called mono, is a viral infection that can cause extreme fatigue, fever, sore throat, and swollen glands. The Epstein-Barr virus causes most cases, but other viruses can cause similar illness.
Mono is called the kissing disease because it often spreads through saliva during kissing. It can also spread by sharing drinks, utensils, toothbrushes, or close contact with coughs and sneezes.
Most mono cases are caused by the Epstein-Barr virus. Cytomegalovirus and other viruses can also cause mono-like symptoms. These viruses spread through saliva and other bodily fluids.
Teens and young adults are most likely to have noticeable mono symptoms. Young children can get infected too, but their symptoms are often mild or mistaken for a cold.
Recognizing possible mono symptoms matters because recovery can take weeks, fatigue can linger, and the spleen may become enlarged. Knowing when to seek care can help reduce complications and avoid unsafe activity.
Common symptoms include extreme tiredness, fever, very sore throat, swollen lymph nodes, swollen tonsils, headache, body aches, loss of appetite, rash, and night sweats. Some people also have upper-left belly discomfort from an enlarged spleen.
A healthcare professional may diagnose mono based on symptoms, a physical exam, and blood tests. They may check for swollen lymph nodes, throat inflammation, and signs of an enlarged spleen.
Tests may include a monospot screening test, Epstein-Barr virus antibody tests, cytomegalovirus antibody tests, immunoglobulin M testing, and a complete blood count. A complete blood count can show changes in white blood cells that may support further evaluation.
Mono is caused by a virus, while strep throat is caused by bacteria. Both can cause a severe sore throat, but strep may improve with antibiotics when prescribed, while antibiotics do not treat viral mono. Testing can help tell them apart.
Consider seeing a doctor if you have severe sore throat, swollen glands, fever, and extreme fatigue lasting more than a week. Seek urgent care right away for sharp upper-left abdominal pain, trouble breathing or swallowing, dizziness, or fainting.
Many people start feeling better within two to four weeks after symptoms begin. Extreme fatigue can last for several months in some cases, so returning to normal activity may need to be gradual.
Getting classic mono more than once is uncommon. After infection, the virus stays in the body and usually becomes dormant. Reactivation can happen, especially in people with weakened immune systems, but it often causes milder symptoms.
Yes, mono can spread through saliva and other bodily fluids. People are often most contagious while they have symptoms, but some can spread the virus for months after recovery.
Most people recover without lasting problems, but complications can happen. These may include an enlarged or ruptured spleen, liver inflammation, anemia, heart inflammation, breathing problems, or rare nervous system issues.
Soft foods such as smoothies, yogurt, soups, and mashed potatoes may be easier to swallow when your throat hurts. As appetite returns, fruits, vegetables, whole grains, and lean proteins can support recovery. Avoid alcohol during recovery to help protect the liver.
