Out of 2456 examined live births, congenital malformations were observed in 66 cases. The prevalence of congenital malformation was 66 (2.6%) at 95% confidence interval (4.19-1.98) of total live births. The genitourinary system was the most common system involved with congenital malformations being 16 (24.2%), followed by musculoskeletal system 14 (21.2%), and cardiovascular system 12 (18.2%).
