The U.S. reported double-digit increases in both COVID-19 cases and hospitalizations last week, according to the CDC's COVID-19 data tracker weekly review published April 29.
Nine findings:
Cases
1. As of April 27, the nation's seven-day case average was 53,133, a 25.2 percent increase from the previous week's average.
Hospitalizations
2. The seven-day hospitalization average for April 20-26 was 1,889, an 18.5 percent increase from the previous week's average. This marks the third consecutive week hospitalizations have increased.
Deaths
3. The current seven-day death average is 334, down 5.3 percent from the previous week's average. Some historical deaths have been excluded from these counts, the CDC said.

4. The seven-day average number of vaccines administered daily was 535,362 as of April 27, a 13.7 percent increase from the previous week.
5. As of April 27, about 257.4 million people — 77.5 percent of the U.S. population — have received at least one dose of the COVID-19 vaccine, and more than 219.5 million people, or 66.1 percent of the population, have received both doses.
6. About 100.3 million additional or booster doses in fully vaccinated people have been reported. However, 49.5 percent of people eligible for a booster dose have not yet gotten one, the CDC said.
