Severe gastroenteritis as presentation of a primary cytomegalovirus infection in an immunocompetent woman

In immunocompetent hosts, symptomatic cytomegalovirus (CMV) infection occurs in around 10% and has traditionally been considered to have a benign, self-limiting course. Active CMV infection in immunocompetent subjects is very rare. However, manifestations of CMV infection in immunocompromised hosts have been extensively reported. We present a case of a 58-year-old immunocompetent woman with a primary cytomegalovirus infection which presented as a severe gastroenteritis and hepatitis.
