Pediatric diseases refer to illnesses and conditions that affect children, typically from birth to adolescence. These can range from common conditions such as asthma, ear infections, and colds to more serious and complex diseases like cancer, diabetes, and genetic disorders. Pediatric diseases may impact physical, emotional, and mental health, and often require specialized care and treatment tailored to the unique needs of children. Research in this area focuses on understanding the causes, prevention, diagnostic methods, and treatments of pediatric diseases to improve the overall health and well-being of children. It may also involve studying the long-term impact of certain diseases on a child's growth and development.
