Cytomegalovirus is the epidemic that no one has ever heard of, said Dr. Mark Schleiss, director of the University of Minnesota Medical School’s division of pediatric infectious diseases and immunology. This virus causes birth defects in children more than any other infectious disease in the United States today.

Schleiss welcomed the study as outstanding and meticulous.

With regard to deafness, he said, the test could alert doctors to potential hearing loss in children infected, even if a hearing child does not show problems, and t tests allow doctors to give preventive medicines or provide hearing aids.
