Is Your Child Sick?TM


Infection Exposure Questions

  • This topic includes information about transmission of common infections. How long to stay out of school or child care is covered.
  • Incubation Period. Time it takes to start having symptoms after contact with infection.
  • Contagious Period. Time during which a sick child's disease can spread to others. Sometimes, children can return to school before this period is over.
  • Infections that cannot be spread to others. Many common bacterial infections are not spread to others. Examples are ear, sinus, bladder, or kidney infections. Pneumonia also cannot be passed to others. Sexually transmitted diseases are usually not spread to children. But, they can be spread if there is sexual contact or shared bathing.

  1. Cold sores: Less than 6 years old, contagious until cold sores are dry (4-5 days). No isolation if sores are on part of body that can be covered. More than 6 years old, no isolation necessary if beyond touching, picking stage.

  2. Diarrhea Precautions: Contagious until stools are formed. Stay home until fever is gone, diarrhea is mild, blood and mucus are gone, and toilet-trained child has control over loose stools. Shigella and E-coli 0157 require extra precautions. Consult your child care provider regarding attendance restrictions.
