Introduction

Neonatal infections are a major cause of morbidity and mortality in newborns, particularly within the first 28 days of life. Understanding the risk factors associated with these infections is essential for developing effective prevention strategies. Neonates are especially vulnerable due to their immature immune systems, making early identification and intervention critical to improving outcomes and reducing the incidence of infections [1].

One of the primary risk factors for neonatal infections is preterm birth. Preterm infants, those born before 37 weeks of gestation, have underdeveloped immune systems and skin barriers, making them more susceptible to infections. The earlier a baby is born, the higher the risk of infection. Preterm infants often require prolonged hospital stays and may need invasive procedures, such as mechanical ventilation or intravenous catheters, which further increase their risk of acquiring infections [2].

Another significant risk factor is the presence of maternal infections during pregnancy or delivery. Infections such as Group B Streptococcus (GBS), urinary tract infections, and sexually transmitted infections can be transmitted from the mother to the baby during childbirth. GBS, in particular, is a leading cause of early-onset neonatal infections, which occur within the first 72 hours of life. Maternal colonization with GBS can lead to the transmission of the bacteria to the newborn during delivery, potentially causing sepsis, pneumonia, or meningitis [3].

Prolonged rupture of membranes (PROM), defined as the rupture of the amniotic sac more than 18 hours before delivery, is another risk factor for neonatal infections. When the membranes rupture, the protective barrier between the sterile environment of the womb and the external world is breached, allowing bacteria to ascend from the vagina into the amniotic fluid and potentially infect the fetus. PROM is particularly concerning in preterm births, where the risk of infection is compounded by the infant's immature immune system [4].

Neonatal infections are also more likely to occur in cases of prolonged or complicated labor. Factors such as the use of intrapartum monitoring devices, frequent vaginal examinations, and the presence of meconium-stained amniotic fluid can increase the likelihood of infection. Additionally, infants born via cesarean section after labor has begun are at a higher risk of infection compared to those delivered via elective cesarean section before labor [5].

Low birth weight is another important risk factor for neonatal infections. Infants with low birth weight, often a consequence of preterm birth or intrauterine growth restriction, have less developed immune systems and are more vulnerable to infections. These infants may also face challenges with temperature regulation, feeding, and maintaining adequate blood sugar levels, all of which can further compromise their ability to fight off infections [6].

Given these risk factors, effective prevention strategies are crucial in reducing the incidence of neonatal infections. One of the most important prevention strategies is the administration of intrapartum antibiotic prophylaxis (IAP) to pregnant women who test positive for GBS or have risk factors for transmission. IAP significantly reduces the risk of early-onset GBS infection in newborns by targeting the bacteria before they can be transmitted during delivery [7].

In the neonatal intensive care unit (NICU), infection prevention measures are critical. Strict hand hygiene practices, the use of sterile techniques during invasive procedures, and minimizing the use of invasive devices whenever possible are essential strategies for reducing the risk of hospital-acquired infections [8]. The implementation of antimicrobial stewardship programs in the NICU can also help reduce the overuse of antibiotics, thereby minimizing the development of antimicrobial resistance and the subsequent risk of difficult-to-treat infections [9].

Breastfeeding is another important preventive measure. Breast milk contains antibodies and other immune-protective factors that help protect newborns from infections. Encouraging and supporting breastfeeding, especially in preterm and low birth weight infants, can provide significant protection against infections. Vaccination is also a critical component of infection prevention. Maternal vaccination during pregnancy, such as the Tdap vaccine to protect against pertussis, can provide passive immunity to the newborn. Additionally, administering routine vaccinations to newborns according to the recommended schedule helps protect them against vaccine-preventable diseases [10].

Conclusion

Understanding the risk factors associated with neonatal infections is vital for developing and implementing effective prevention strategies. By addressing these risk factors through targeted interventions such as prenatal care, intrapartum antibiotic prophylaxis, infection control practices in the NICU, and promoting breastfeeding and vaccination, we can significantly reduce the incidence of neonatal infections and improve outcomes for newborns.
