The answer is: D
Isolation of virus from blood or demonstration of a fourfold or greater rise in antibody is the most reliable means of diagnosis of an acute infection of CMV. Excretion of CMV in the urine or the saliva can persist for months. Clinical findings alone are insufficient to differentiate CMV infection from other acute virus infections.
