Patient's question:
The baby was born not long ago and has poor appetite and pale complexion. The doctor performed a thorough examination and diagnosed it as neonatal sepsis, a critical condition. Our family is very worried. We have sought the help of many experts to treat the child. I would like to ask how neonatal sepsis is caused?Doctor's answer:
Due to the immature immune system of newborns, they are easily infected by bacteria, which can lead to sepsis. The non-specific immune function is not fully developed, with some components missing. Lymph node development is also incomplete. Barrier function is poor. Neonatal sepsis is primarily caused by bacteria entering the bloodstream, multiplying extensively in the blood, producing toxins, and triggering systemic infection. The incidence and mortality rates are high, especially for premature infants who are particularly susceptible to sepsis. Common bacteria include Staphylococcus, followed by Escherichia coli. Infection can occur in utero or during delivery. However, the main route of transmission is postpartum transmission.
