About 24% of inpatients in U.S. hospitals have the coronavirus, matching the peak set in April, according to an internal memo from the U.S. Department of Health and Human Services that was obtained by ABC News.

About 29% of hospitals across the country have more than 80% of their ICU beds filled, according to the memo.

HHS said 34% of ventilators in use are occupied by COVID-19 patients. The peak in April was 45%, according to the agency.

The memo also reported increasing trends with cases and deaths across the country between Dec. 16 and Dec. 22.

During that seven-day period, 1,656,411 new cases were confirmed, according to HHS. This was a 10.8% increase from the previous seven-day period.

There were 18,537 deaths recorded between Dec. 16 and Dec. 22, which was a 7.5% jump from the same period last week.
