<unk>  is a type of neonatal infection and specifically refers to the presence in a newborn baby of a bacterial blood stream infection (BSI) (such as meningitis, pneumonia, pyelonephritis, or gastroenteritis) in the setting of fever. Older textbooks may refer to<unk>  as<unk>  neonatorum". Criteria with regards to hemodynamic compromise or respiratory failure are not useful clinically because these symptoms often do not arise in neonates until death is imminent and unpreventable.<unk>  is divided into two categories: early-onset<unk>  (EOS) and late-onset<unk>  (LOS). EOS refers to<unk>  presenting in the first 7 days of life (although some refer to EOS as within the first 72 hours of life), with LOS referring to presentation of<unk>  after 7 days (or 72 hours, depending on the system used).<unk>  is the single most common cause of neonatal death in hospital as well as community in developing country. It is difficult to clinically exclude<unk>  in newborns less than 90 days old that have fever (defined as a temperature > 38 °C (100.4 °F). Except in the case of obvious acute viral bronchiolitis, the current practice in newborns less than 30 days old is to perform a complete workup including complete blood count with differential, blood culture, urinalysis, urine culture, and cerebrospinal fluid (CSF) studies and CSF culture, admit the newborn to the hospital, and treat empirically for serious bacterial infection for at least 48 hours until cultures are demonstrated to show no growth. Attempts have been made to see whether it is possible to risk stratify newborns in order to decide if a newborn can be safely monitored at home without treatment despite having a fever. One such attempt is the Rochester criteria.
