When should you isolate a child?

A child should be isolated if they exhibit symptoms of a contagious illness, such as fever, cough, or rash, to prevent the spread of infection to others. Additionally, if a child has tested positive for a contagious disease, they should remain isolated according to public health guidelines until they are no longer contagious. It's important to monitor the child's health and consult a healthcare professional for specific recommendations. Always follow local health regulations and school policies regarding isolation and return to activities.
