Reviewer's report:
Well written manuscript. 
I have one major query - A substantial number of patients had "undetectable" CMV load. Would these
patients still qualify as having CMV disease ? Please provide details of the PCR detection limit etc. 
Minor comments - 
In the paragraph - Of the 117 immunocompromised patients, 34 (29.1%) had HIV infection with a
median CD4 count of 19 cells/mm3 (range: 1-187), 30 (25.6%) had autoimmune diseases, 24 (20.5%)
had organ transplantations, 21 (12.1%) had cancers, and 10 (8.6%) had inflammatory bowel disease
(IBD) - If you add up the numbers it comes to 119, can you please check and correct it .
Provide details of concomitant extra - gastrointestinal CMV infections in the patients in whom it was
present.
