Infectious Diseases Conditions and Diagnoses

Mono

What is infectious mono (mononucleosis)?

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 2-4 weeks, but recovery can take up to 3 months.

Symptoms to look for:

  • Fever
  • Sore throat
  • Enlarged lymph nodes

Treatment

  • Do not give your child ampicillin during his/her illness. It could cause a drug rash.
  • If your child has a fever, make sure that he/she drinks an extra 10-12 cups (2.5-3 quarts) of liquid each day while his/her temperature is above normal.
  • Your child should be on bed rest when his/her temperature is above normal. Limit your child's activity so that he/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 4-6 weeks after he/she has recovered. This will prevent injury to his/her 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 his/her shoulder to the doctor.

Preventive action

  • 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/her
