The term "birth defect" is a medical and general term used to describe a condition existing from birth. It is often used in healthcare, public health, and scientific discussions. * It is typically used as a countable noun (e.g., a birth defect, several birth defects). * While clinically accurate, some consider the term "defect" to have negative connotations.
