Pediatric diseases refer to medical conditions that specifically affect infants, children, and adolescents. These diseases can range from common illnesses like the common cold to more serious conditions such as asthma or diabetes. Early diagnosis and treatment are crucial, as children's bodies are still developing and may respond differently to illnesses compared to adults. Some pediatric diseases are congenital, meaning they are present at birth, while others may develop as a child grows. Vaccinations play a vital role in preventing many infectious diseases, such as measles and whooping cough. Pediatricians specialize in diagnosing and treating these conditions to ensure healthy growth and development in young patients.
