Screen Positive Follow-Up

Why has a referral been made to an Infectious Diseases (ID) Clinic?

The hearing loss risk factor blood spot screen was screen positive (CMV detected).  The positive result indicates a high chance of congenital cytomegalovirus (cCMV) infection.  Infectious Diseases specialists are experts in the care of babies and children with cCMV infections.

What can be expected from the first appointment?

At the baby’s first appointment:

  • Questions will be asked about the pregnancy and health of the baby
  • The baby will have a physical examination to look for any symptoms of cCMV infection
  • The baby will have blood, urine, and/or saliva samples collected.  Ultrasound or other imaging tests will also be arranged.
  • Referrals to other specialists may be made

How often will a baby be followed by the Infectious Diseases (ID) Clinic?

The baby’s first appointment will help determine how often and for how long they need to be followed by the ID clinic.  Babies who are confirmed to have cCMV infection and are symptomatic will be followed more frequently.  Babies who are confirmed to have cCMV infection but have no symptoms may have their care transferred to a local community pediatrician for continued monitoring.  The ID doctor will discuss their recommendations with each family.

Will other health care specialists need to be involved?

There are a number of specialists who may already be or may become involved in the care of a baby with cCMV infection.  These specialists may include:
