Mononucleosis (mono) is an infection. It's usually caused by the Epstein-Barr virus. People get it through contact with saliva and with mucus from the nose and throat. A child can get mono from kissing an infected person. Or a child may get it after sharing a glass, fork, or spoon with someone who has mono.
Symptoms include a fever and a very sore throat. Your child may also have swollen glands and tonsils and feel weak and tired.
Sometimes the virus causes the spleen to swell. The spleen is an organ in the upper left side of the belly. If it ruptures, it's an emergency. So it's important for your child to avoid rough sports or challenging activities while your child has mono. These can put extra pressure on the spleen.
It takes time to recover from mono. The lymph nodes in your child's neck may be larger than normal for a while. Most children get better after 2 to 4 weeks. But it could take several more weeks before your child's normal energy is back. Lots of rest will help your child feel better.
Mononucleosis, or "mono," is a common illness caused by a virus. It's often seen in teens and young adults. It can cause a bad sore throat, swollen neck glands, and fever. Some people feel tired and weak for weeks or months after getting sick.
Mono usually goes away on its own, but rest and good self-care can help you feel better. Mono is nicknamed "the kissing disease" because that's one way the virus is spread. If you have mono, don't kiss anyone or share things like drinking glasses, eating utensils, or toothbrushes.
The most common symptoms of mono include fever, sore throat, swollen lymph nodes, and feeling tired and weak. Mono can also cause pain in the upper left part of your belly, which may mean that the spleen is enlarged. Symptoms usually start 4 to 6 weeks after you're exposed to the virus.
Treatment for mono usually involves self-care measures like rest and over-the counter medicines to reduce pain and fever. In severe cases, corticosteroids may be used to reduce swelling of the throat, tonsils, or spleen.
Your doctor will ask you questions about your symptoms and will examine you. You may also need blood tests to check for mono and signs of mono. Blood tests can also help rule out other causes of your symptoms.
The virus that usually causes mono—the Epstein-Barr virus (EBV)—can be spread through:
EBV isn't spread by casual contact. You can live in the same house with a person who has mono and never be infected with the virus. But a person who has a weakened immune system may be at higher risk for mono.
You can pass EBV to others for several weeks or months during and after the time you are first infected with EBV. The virus can also become active and spread to others from time to time throughout your life.
Mononucleosis (mono) is a common illness caused by a virus. It can start with a sore throat and swollen glands. And then it can leave you feeling tired and weak for weeks or months. Mono goes away on its own, but rest and good self-care can help you feel better.
Mono usually is caused by the Epstein-Barr virus (EBV). It's most often seen in teens and young adults. Children can get the virus, but it often goes unnoticed because their symptoms are mild. Older adults usually don't get mono. That's because they have immunity to the virus.
