Summary

When planning activities for a surveillance programme, it’s important to consider the scope of the programme. Which congenital anomalies might a programme plan to monitor? This chapter presents a list of congenital anomalies to consider in the initial phase of monitoring. They were chosen because they are relatively easy to identify at birth, have a significant public health impact, and some of them have the potential to be prevented through public health interventions.

Chapter 4 provides:
  • Clinical information about four major types of congenital anomalies
  • Relevant ICD-10 and other codes
  • Access to photographs that exhibit clinical characteristics of featured diagnoses.
Highlights
  • Use the Photo Atlas to view photographs and relevant classification codes of birth defects. 
  • The Atlas can assist program staff in diagnosing and coding birth defects.
