Introduction
Premature infants usually require more than three days to overcome the risk of infection. The duration of infection in preterm infants often depends on the site of infection. If the infection is at the umbilical site, it generally takes about three days to control the umbilical infection. However, if the infant develops a lung infection after birth, it typically requires a relatively longer period for the infection symptoms to gradually subside.

The duration of infection in preterm infants often depends on the site of infection. If the infection occurs at the umbilical area, it generally takes about three days to control the umbilical infection. However, if the infant develops a lung infection after birth, it may take a relatively longer time—approximately 15 to 30 days—for the infection symptoms to gradually subside. Therefore, the specific duration of infection can vary significantly among preterm infants.
After birth, proper cleaning and hygiene of the umbilical area should be maintained to prevent infection and inflammation of the umbilical wound. As the area heals gradually, the umbilical cord typically forms a scab and falls off naturally within 7 to 15 days. It is recommended to wipe the umbilical area with iodine solution under medical guidance, which helps prevent inflammation.
It is also advised to disinfect diapers and clothing promptly after the preterm infant's birth to avoid bodily infections. Additionally, since preterm infants have relatively weak immune systems, adequate warmth should be maintained to prevent colds and chills.
