The 7-day average of new US Covid cases continued to fall to around 24,155 infections per day on Tuesday, according to Johns Hopkins University, and the average pace of daily deaths is also falling.

The latest data from the Centers for Disease Control and Prevention shows that half of American adults are now fully vaccinated against Covid.

For those who are not vaccinated, CDC Director Dr. Rochelle Walensky to be cautious about the upcoming Memorial Day holidays, noting that those who got a shot are protected.

“If you are not vaccinated, our instructions have not changed for you,” Walensky said at a press conference at the White House on Tuesday. “You are still at risk of infection. You still need to mask and take other precautions.”

Last year, US Covid cases rose after the holiday weekend when vaccines were not available at the time.

US Covid cases

The US reports an average of 24,155 infections per day over the past week, a 23% decrease from the previous week and a sharp decrease from the last peak of more than 71,000 cases per day in mid-April.

A CNBC analysis of the Hopkins data shows that the average number of cases in 41 states and the District of Columbia has decreased by at least 5% over the past week.

US Covid deaths

According to Hopkins data, the US has recorded an average of 520 Covid deaths per day over the past week.

The total number of reported Covid deaths in the US since the pandemic began is now about 591,000.

US percentage of the vaccinated population

About 50% of the US population had at least one shot, according to the CDC, with more than 131 million Americans, or nearly 40%, fully vaccinated.

Of those over 18, around 62% have received at least one dose of vaccine, while 50% are now fully vaccinated. President Joe Biden’s goal is to bring the proportion of adults on one dose or greater to 70 percent by July 4th.

US vaccine shots administered

The 7-day average of vaccinations given in the US is 1.8 million per day over the past week, according to CDC data. That number has hovered between 1.7 and 2 million for more than a week.
