When a child is unwell, they show many visible signs of sickness, such as whining more, playing less, and lethargy. Children also exhibit symptoms indicative of an illness, including runny nose, coughing, low-grade fever, sneezing and gastrointestinal upset (vomiting or diarrhea). Fortunately, common childhood illnesses typically clear up on their own with rest, at-home care and over-the-counter medicines. It is normal for a child who is feeling unwell to exhibit the following symptoms: • Fever • Headache • Malaise (tired) • Diarrhea • Nausea and vomiting • Rash • Sore throat • Cough • Swollen lymph glands • Excessive drooling (in young children) • Abdominal pain   However, some symptoms are indicators of a more concerning condition or complication, especially if the child has a suppressed immune system, diabetes, asthma, or other chronic illness. Symptoms that require medical attention include: • Difficulty breathing • High fever (over 104ºF) • Dehydration
