When infected with CMV, most women have no symptoms and very few have a disease resembling infectious mononucleosis. It is their developing fetuses that may be at risk ...

Plus, how older adults can protect themselves. Plus, how older adults can protect themselves. ... “In adults over the age of 65, symptoms almost always include a cough, whereas with the flu ...
This treatment alone is not wholly effective, and many people still experience other symptoms such as lung disease and noninfectious inflammatory symptoms. This treatment replenishes Ig subtypes that the person lacks, is given at frequent intervals for life, and is thought to help reduce bacterial infections and boost immune function. [ 25 ]
CMV colitis may be clinically manifested with diarrhea (usually non-bloody), abdominal pain, weight loss and anorexia. The diagnosis of CMV colitis is based on serology, CMV antigen testing and colonoscopy with biopsy. Clinical suspicion should be aroused in the setting of immunocompromised patient but it is much rarer in immunocompetent patient.
