What the new AAP congenital CMV report means for parents this week

Editorial context for parents, not medical advice.

## What changed
On 21 September 2026 the American Academy of Pediatrics published Care of the Infant With Congenital Cytomegalovirus Infection in Pediatrics. Congenital CMV is a leading infectious cause of childhood hearing loss. Many babies look well at birth; hearing can still change later.

## Background
CMV is common. Infection before birth is congenital CMV. Effects range from none to hearing loss, vision issues, or developmental delay. Hearing change can be the only early clue. Hospitals have used different testing rules.

## What the report recommends
Hearing-targeted plus expanded testing: test newborns who do not pass hearing screening, and test babies with physical findings linked to cCMV. Diagnosis can allow timely treatment when indicated and closer follow-up. Access is treated as an equity issue.

## Competing viewpoints
Targeted testers worry universal screening finds many babies who never need treatment. Universal-screening advocates say targeted programs miss babies who pass the first hearing test and lose hearing later. The AAP path sits in the middle.

## Nearby stories
Vitamin K refusals at birth have risen in U.S. hospital data this year. Without the shot, rare but severe bleeding is much more likely in the first months. AAP also issued clinician FAQs on congenital measles as U.S. cases rose. On 19 September a San Francisco family delivered baby Cielle Ray in Golden Gate Park after traffic blocked the hospital run; mother and baby were reported well.

## What to watch next
Ask whether your hospital tests for cCMV after a failed hearing screen, who owns follow-up if a test is positive, and whether you leave with written discharge instructions.
