Question
After 7 days of birth, the umbilical cord of a newborn has not fallen off and has developed a purple-red ulcerous surface. What could be the cause of this? How should it be treated symptomatically?
Answer
According to the description, it may be due to improper care of the umbilical area after birth, leading to infections by Staphylococcus aureus, Escherichia coli, or Streptococcus hemolyticus, among other bacteria. It is recommended to bring the child to the hospital for a detailed examination and to undergo sterilization and anti-inflammatory treatment. Wishing the baby a healthy and happy recovery.
