What is cCMV?

  • CMV or cytomegalovirus is “the most common virus most people never heard of” (Demmler-Harrison).
  •  More than half of the US population has had a CMV infection by 40 years old (CDC).
  • It is typically harmless and can cause cold-like symptoms; 90% of adults and many children show no symptoms at all.
  • When a baby is born with a CMV infection, it is called congenital CMV (cCMV).
