<unk> s are<unk> s of the neonate (newborn) acquired during prenatal development or in the first four weeks of life<unk>  period).<unk> s may be contracted by mother to child transmission, in the birth canal during childbirth, or contracted after birth. Some<unk> s are apparent soon after delivery, while others may develop in the postnatal period. Some<unk> s such as HIV, hepatitis B, and malaria do not become apparent until much later. There is a higher risk of<unk>  for preterm or low birth weight neonates. Infant respiratory distress syndrome is often a condition of preterm neonates that can have long-term negative consequences, it can also arise following an<unk> . In some instances,<unk>  respiratory tract diseases may increase the susceptibility to future respiratory<unk> s and inflammatory responses related to lung disease. Antibiotics can be effective for<unk> s, especially when the pathogen is quickly identified. Instead of relying solely on culturing techniques, pathogen identification has improved substantially with advancing technology; however, neonate mortality reduction has not kept pace and remains 20% to 50%. While preterm neonates are at a particularly high risk, all neonates can develop<unk> .<unk>  may also be associated with premature rupture of membranes (breakage of the amniotic sac) which substantially increases the risk of<unk>  sepsis by allowing passage for bacteria to enter the womb prior to the birth of the infant.<unk>  can be distressing to the family and it initiates concentrated effort to treat it by clinicians. Research to improve treatment of<unk> s and prophylactic treatment of the mother to avoid<unk> s of the infant is ongoing.
