Twenty-six million people in the United States -- which is 7.8% of the country's population -- have received one or more doses of COVID-19 vaccines, according to a report from the U.S. Department of Health and Human Services.

COVID-19 cases and hospital admissions are continuing to decline nationally, while adult intensive care unit occupancy rates and deaths remain high in several states.

The country's seven-day average for new COVID-19 hospital admissions has dropped from a peak of 16,485 on Jan. 9 to 11,369 -- a 31% decline, the report said.

California, Texas, Georgia, Alabama and Oklahoma are the only states where ICU occupancies are above 85%, the report said.

Dr. Anthony Fauci, chief medical adviser to U.S. President Joe Biden, said new, more contagious variants of the novel coronavirus are the top concern in the country right now and that the next six weeks will be critical.

"We're going to be doing … a full-court press on non-pharmacologic interventions [like masks] as well as getting as much vaccine out as we possibly can," Fauci, who is also the director of the National Institute of Allergy and Infectious Diseases, said at the International Aids Society conference on Tuesday.

"It's a very stressful situation ... when you have that much virus circulating, you're going to get a lot of mutations, no doubt about it," he added. "It's almost a race of trying to suppress the level of replication before we get so many accumulation of both the South African and other mutants as well as mutants of our own."

Maryland has identified two more confirmed cases of the new, more contagious B1351 variant of the novel coronavirus, which was first detected in South Africa, Gov. Larry Hogan said Tuesday.

The two patients are Montgomery County residents who recently traveled abroad, according to Hogan.

"Contact tracing is underway, and close contacts are isolating," the governor wrote on Twitter.

Maryland’s first case of the South Africa variant, in the Baltimore region, was announced on Saturday.

"The B.1.351 variant has not been shown to cause more severe illness or increased risk of death, though it is believed to be more transmissible," Hogan tweeted. "Initial evidence suggests that vaccines are still likely to be protective against the variant."

An accommodation facility for refugees in the German city of Cologne has been hit by new, more contagious variants of the novel coronavirus, city officials said.

At least 41 residents of the Herkulesstrasse facility have tested positive for COVID-19. Variants first identified in South Africa or Brazil have been detected in 31 of them so far, according to a statement from the city government on Sunday.

At least 16 staff members at the facility have also tested positive for COVID-19, with the South Africa variant detected in 11 of them so far. Variant analysis is still pending on the other five, according to the statement.

All residents of the facility have been under quarantine since Friday, while the site has been under surveillance since Sunday. Entry into the refugee accommodation center, which can house up to 600 people, is currently banned, according to the statement.

The first known COVID-19 cases were confirmed among two employees at the facility about 10 days ago, while the first case of a variant was confirmed last week, according to the statement.

Dr. Harald Rau, head of Cologne's public health department, said the detection of variants at the refugee accommodation center "is a clear alarm signal for all of us."

"I ask all people in Cologne to avoid contact even more consistently than before and to follow the distance and hygiene rules of infection protection," Rau said in a statement Sunday.
