Thus cytomegalovirus can be transmitted through oral, anal, and genital sexual contact, through kissing, through blood exchange (such [...]

Some scientists have been impressed by initial reports of this test’s success: In one recent study, researchers obtained blood from radical prostatectomy patients before they underwent surgery.
