May 30 - "4,000 out of 4 million"

From the Baylor College of Medicine's Winter 2008 Updates Newsletter:

"Congenital CMV infection is the most common viral congenital infection. Of the approximately 4 million babies born each year in the U.S., 1 percent, or 40,000 babies, are born with congenital CMV infection. Ninety percent of those babies born with congenital CMV disease each year will have no symptoms of congenital CMV infection at birth, yet 10 to 15 percent will have hearing loss. The remaining 10 percent or 4,000 infants, may have serious illness and long-term developmental disorders and are at risk for progressive hearing loss."
