Weekly COVID-19 hospitalizations have risen by more than 10% across the country, according to new data published by the Centers for Disease Control and Prevention, marking the largest percent increase in this key indicator of the virus since December.

At least 7,109 admissions of patients diagnosed with COVID-19 were reported for the week of July 15 nationwide, the CDC said late Monday, up from 6,444 during the week before. 

Another important hospital metric has also been trending up in recent weeks: an average of 0.73% of the past week's emergency room visits had COVID-19 as of July 21, up from 0.49% through June 21.
