The overall incidence of omphalitis varies from 0.2% to 0.7% in industrialized countries. [29] Its incidence is higher in hospitalized preterm infants than in full-term infants. Omphalitis is usually sporadic but, rarely, epidemics occur (eg, due to S aureus or group A Streptococcus). [30, 31, 32]

Sex- and age-related demographics

No sex predilection has been reported, although males may have a worse prognosis than females.

In full-term infants, the mean age at onset is 5-9 days. In preterm infants, the mean age at onset is 3-5 days.
