State and medical officials, along with parents, held a news conference in Hartford on Friday to raise awareness about CMV.

Although it's a considered a common disease, CMV has no symptoms. Most people do not experience any harmful affects.

It can be spread through saliva and tears.

One out of every 200 babies are born with cytomegalovirus, also known as CMV. Out of those 200, one out of five could have long-term health problems, such as hearing loss.

Treatment includes anti-virtual medication that needs to be taken within 21 days of a baby's birth.

Last legislation session, a bill was passed to have all babies be screened for CMV, not just those who fail a hearing test.

Connecticut is second state to require universal CMV screening for babies.

Health officials say they are working on implementing the law and providing prevention information.

"Many children before they enter kindergarten have had it. So, we know that, that highest burden of diseases in those little ones. So, we need to be able to educate people that take care of children in daycare centers and preschools and the mothers of young children," says Dr. Jody Terranova, deputy commissioner of public health.
