Congenital Measles: Frequently Asked Questions

Posted on September 11, 2026

Congenital Measles: Frequently Asked Questions is a new resource page on Red Book Online (RBO) providing guidance on congenital measles, including the definition, clinical presentation, evaluation and management, infection prevention and control considerations, long-term follow-up, and prevention. It was developed in response to ongoing measles outbreaks and the resulting increase in congenital measles cases in the United States. Find answers to questions such as:
  • What is congenital measles?
  • How do infants with congenital measles infection present?
  • How should neonates be tested for measles?
  • What additional acute and long-term clinical management should be considered?
  • What isolation precautions are recommended?
  • How can measles during pregnancy and congenital measles be prevented?
References are included where evidence is available; where evidence is limited, the guidance reflects the opinion of subject matter experts in infectious diseases, public health, infection prevention and control, and fetal and newborn medicine.
