Illness in children can range from mild to severe and may include common conditions like colds, flu, and stomach viruses. Symptoms often include fever, cough, and fatigue. Young children are particularly vulnerable due to their developing immune systems, making it essential for parents to monitor their health closely. Preventive measures, such as regular handwashing and vaccinations, can help reduce the risk of illness. If a child shows persistent symptoms or difficulty breathing, it is important to seek medical attention. Early diagnosis and treatment can lead to better outcomes and a quicker recovery for young patients.
