Mono

Infectious mononucleosis, commonly called "mono," is an infectious disease that affects the lymph tissues. It is spread by mouth.

Your child may feel better in two to four weeks, but recovery can take up to three months.

  • Fever
  • Sore throat
  • Enlarged lymph nodes 
  • Do not give your child amoxicillin or amoxicillin clavulanate (Augmentin) during his or her illness. It could cause a drug rash.
  • If your child has a fever, make sure that he or she drinks an extra 10-12 cups (2.5-3 quarts) of liquid each day while a temperature is above normal.
  • Your child should be on bed rest when his or her temperature is above normal. Limit your child's activity so that he or she doesn't get exhausted.
  • Do not let your teenager drink alcohol. Alcohol makes the liver work harder.
  • Have your child avoid heavy lifting, contact sports and vigorous activity for four to six weeks after recovery. This will prevent injury to the spleen. The spleen may become enlarged, and injuries may cause severe bleeding.
  • Immediately report any pain in the left upper area of your child's abdomen or in the shoulder to the doctor.
  • Don't let your child kiss or share oral secretions
  • Don't share eating and drinking utensils or dishes
  • Wash eating and drinking utensils in hot, soapy water
  • Tell others who come in close contact with your child to wash their hands after being close to him or her
