CMV infections in non-immunocompromised critically ill patients

This subject has been getting lot of press. Here's the latest paper from Critical Care Medicine:

Conclusions: Active cytomegalovirus infection occurs frequently in nonimmunosuppressed patients in intensive care, especially in those with positive cytomegalovirus serology, intensive care unit stay ≥5 days, severe sepsis, and high disease severity, in whom the rate of cytomegalovirus infection is up to 36%. Mortality rate is significantly doubled with cytomegalovirus, but a cause-effect relationship cannot be established yet.
