In group settings like daycare and preschool, a handful of infectious illnesses tend to circulate repeatedly among young children. Based on CDC guidance, here’s an overview of common illnesses and how to manage them at home.
Illnesses That Come Up Often
Hand, foot, and mouth disease, caused by coxsackievirus or other enteroviruses, brings mouth sores and a rash on the hands and feet, and tends to circulate in summer and fall. Ear infections often follow a cold, when fluid builds up behind the eardrum. Croup is an upper airway infection marked by a hoarse voice and a barking cough. RSV is a respiratory virus that circulates in fall and winter and can hit younger infants harder than older children.
What Helps at Home
Most of these illnesses tend to resolve with rest and plenty of fluids. Since mouth sores from hand-foot-mouth disease can make eating painful, soft, mild foods are often easier to manage, and cool or humid air can help ease a croupy cough.
When to Return to Daycare or Preschool
Waiting until your child is fever-free and feels more like themselves before returning is generally recommended. For a contagious illness like hand-foot-mouth disease, waiting until blisters have crusted over or symptoms have eased can help limit spread. It’s worth checking your specific program’s own policy as well.
When to Seek Care Right Away
Chest retractions or visible difficulty breathing, bluish lips or face, or signs of dehydration such as no fluid intake and very little urine output call for emergency care right away. Severe throat swelling that makes swallowing difficult, or a high fever paired with extreme lethargy, are also considered warning signs. This information is based on U.S. (CDC) guidance; if you live elsewhere, check with a local pediatric provider for country-specific recommendations.
