Washington, Mar 7 (IANS): The United States continues to see a decline in new Covid-19 cases, deaths and hospitalizations as more than 85 million vaccine doses have been administered.
Key indicators of Covid-19 transmission in the United States have continued to fall since early January, Xinhua news agency reported on Saturday.
A total of 66,481 new cases and 1,840 new deaths were reported on Thursday, according to the data updated by the US Centers for Disease Control and Prevention (CDC) on Friday.
The seven-day average of newly reported cases declined for 43 consecutive days since January 11, CDC data show.
There has been an overall decline of 74.9 per cent of the seven-day moving average since the highest seven-day average of 249,360 on January 11.
Meanwhile, the seven-day average of new deaths has declined by 43.1 per cent since January 13, according to the CDC.
Hospital admissions of patients with confirmed Covid-19 decreased 67 per cent from the national seven-day average peak of 16,540 admissions on January 9 to a seven-day average of 5,490 admissions on March 2, CDC data show.
The average number of daily admissions fell by 14.8 per cent this week compared to the previous week.
Though key indicators have dropped recently, the baseline level of new cases remains high.
"The baseline level of coronavirus cases needs to fall further before the country can confidently resume normal activities, even as the vaccine rollout accelerates," said Anthony Fauci, the country's top infectious disease expert.
Fauci noted that in past periods of the pandemic, "when we started to pull back prematurely, we saw the rebound. We definitely don't want that to happen."
Over 114 million vaccine doses have been distributed across the United States as of Friday, and more than 85 million doses have been administered, CDC data show.
More US states have announced decisions to drop mask mandates despite emerging coronavirus variants, drawing criticism from experts.
A total of 2,753 infection cases of coronavirus variants had been reported in the United States as of Thursday, according to the CDC.
The vast majority of these cases, 2,672, were caused by the variant known as B.1.1.7, which was originally detected in Britain.
There were 68 cases of a new strain initially discovered in South Africa, called B.1.351, and 13 cases of the P.1 strain first discovered in Brazil.
Modeling data suggest that B.1.1.7 could become the predominant variant in the United States in March.
Experts are also concerned about some worrisome variants that are in places like California and New York.
The variant in California, known as B.1.427/B.1.429, spreads more easily than its predecessors and is now dominant in the state, according to scientists at the University of California, San Francisco.
Studies are underway to determine whether variants cause more severe illness or are likely to evade immunity brought on by prior illness or vaccination, according to the CDC.
