Second reported infant dies after testing positive for coronavirus in U.S.

The big picture: The fatality rate for COVID-19 in the U.S. is highest among those over 85 years old, the CDC found in its initial study on patient reactions to the virus, conducted from February through mid-March.

• No ICU admissions or deaths related to COVID-19 were reported among Americans under 19 years old as of that study's publish date, and the hospitalization rate for those younger than 19 ranged from 1.6% to 2.5%.
• The infant in Connecticut "was brought unresponsive to a hospital late last week and could not be revived," Lamont said.

What they're saying: "This is a virus that attacks our most fragile without mercy. This also stresses the importance of staying home and limiting exposure to other people. Your life and the lives of others could literally depend on it. Our prayers are with the family at this difficult time," Lamont tweeted on Wednesday.

• Lamont did not say at Wednesday's press conference whether the infant's death was being investigated further.
