Infección por citomegalovirus como causa de diarrea grave rebelde en un lactante inmunocompetente

Cytomegalovirus infection is a frequent cause of complications in immunodeficient patients. In healthy hosts, cytomegalovirus infection is usually asymptomatic. We describe a case of a 3 month old immunocompetent boy who suffered from protracted diarrhoea that required parenteral nutrition. After treatment with ganciclovir he recovered without any after effects.
