A fever in a neonate younger than 28 days requires which initial management?

Fever in a neonate under 28 days signals a high risk of serious bacterial infection because newborns have immature immune defenses and infections can progress rapidly with minimal or non-specific symptoms. This makes urgent evaluation essential rather than waiting for symptoms to resolve on their own. The best initial management is an emergent sepsis workup that includes obtaining blood and urine cultures and starting empiric intravenous antibiotics if there is any risk for bacteremia or meningitis, followed by hospitalization for close monitoring. Cultures help identify the offending organism and guide targeted therapy, while starting IV antibiotics promptly helps control infection and prevent deterioration even before results are back. Hospital observation ensures the infant can be monitored for signs of clinical worsening and can receive ongoing IV therapy as needed. In addition to blood and urine cultures, the workup may include a complete blood count and possibly a lumbar puncture to assess for meningitis, depending on the clinical assessment and local guidelines. The key point is that this age group cannot be managed safely with discharge, reassurance, or outpatient oral antibiotics alone, because of the high risk and potential for rapid progression of serious infection.
