World Birth Defects Day (WBDD), observed on March 3 each year, unites people and organizations working in the field of birth defects, also known as congenital anomalies, congenital disorders or congenital conditions. There are many types of birth defects and this day recognizes our collective voice in raising awareness for all birth defects.
