Mononucleosis, also known as “mono,” is caused by a germ called the Epstein-Barr virus. Though best known for causing swollen glands and fatigue, mononucleosis can take many forms. Most children with mono recover without any problems. But the illness can take a long time to go away. In some cases, mono can cause problems with the liver, spleen, or heart. So it is important that mono be diagnosed and the child watched carefully.
In children, the most common symptoms include:
Tender or swollen lymph nodes in the neck or armpits
Sore muscles or stiffness
Loss of appetite, nausea
Dull pain in the stomach area
Because it is a viral infection, antibiotics won’t cure mono. The best treatment for mono is rest. A child with mono should also drink lots of fluids. To help your child feel better and recover sooner:
Make sure the child gets plenty of rest.
Keep the child warm.
Feed the child plenty of clear, room-temperature fluids, such as water or apple juice.
Do not let anyone smoke around the child.
Treat the child’s fever, sore throat, or aching muscles with children’s acetaminophen. NEVER give your child aspirin.
Symptoms usually last for a few weeks, but can sometimes last for one to two months or longer. Even after symptoms have gone away, your child may be tired or weak for some time.
While you’re caring for a child with mono:
Wash your hands with warm water and soap often, especially before and after tending to your sick child.
Monitor your own health and that of other family members
Limit a sick child’s contact with other children.
Clean dishes and eating utensils used by a sick child separately in very hot, soapy water. Or run them through the dishwasher.
