Childhood diseases, also known as pediatric diseases or childhood illnesses, are health conditions that primarily affect infants, children, and adolescents. These illnesses can vary widely in their nature, ranging from infectious diseases caused by bacteria, viruses, or parasites to genetic disorders and chronic conditions.

Preventive measures, such as vaccinations, regular check-ups, and a healthy lifestyle, play a crucial role in minimizing the impact of childhood diseases. Timely diagnosis and appropriate medical care are essential for managing these conditions and ensuring the well-being of children.
