There are many types of birth defects and this day recognizes our collective voice in raising awareness for all birth defects. 

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. WHO is one of several collaborating global organizations to raise awareness of this serious global problem and advocate for more birth defects prevention, surveillance, care, and research.
