- Abstract -

The CMV infection represents the most common congenital viral infection, while fetopathy is the most frequent infection, transmitted from mother to fetus. Most cytomegalovirus infections remain undiagnosed, due to the lack of clinical signs, with tendencies of intermittent reactivation, without relevant symptoms. The infection is diagnosed with virological and serological identification methods. In practice, the serology tests must be correlated with the virology tests, both to establish a predictive diagnosis of CMV infection and to reveal the ways in which the virus is transmitted.

Key words: CMV infection, methods of diagnosis, serology tests.
