Which of the following is a potential symptom of E. coli infection in neonates?

Diarrhea is a common symptom of an E. coli infection in neonates. E. coli, particularly specific strains such as Enterohemorrhagic E. coli (EHEC), can cause gastrointestinal distress resulting in diarrhea, which may be profuse and watery. In neonates, the presence of diarrhea can indicate a severe infection, as their capacity to compensate for fluid loss is limited, making it crucial to identify and manage this condition promptly.

While jaundice, rash, and dehydration can also be associated with certain infections or conditions in neonates, diarrhea specifically points to the gastrointestinal impact of E. coli. Understanding the clinical presentation is important for timely management and intervention which can include providing supportive care and monitoring for complications related to fluid loss.
