The number is back before Thanksgiving and Christmas, when the virus was blamed for spreading the virus in the US for disregarding holiday travel and safety warnings.
According to the Johns Hopkins University Epidemic Tracker, the United States on March 4 reported more than 40,000 new cases of COVID-19 in a single day for the first time in five months.
On January 8 in the country facing the epidemic, the number increased to more than half a million faults in about 300,000 new cases.
But it is now back to levels before Thanksgiving and before Christmas, when gathered in defiance of holiday travel and safety warnings blamed for spreading the virus further into the Americas.
Another encouraging sign by the United States with its vaccination campaign is that daily deaths and hospitalizations from COVID-19 are also down.
Three vaccines are currently being administered in the country and the Biden administration says the campaign to awaken 100 million people in their first 100 days in office is ahead of schedule.
The number of people vaccinated is now close to surpassing the number of cases that began a year before the global epidemic.
But amid the stream of good news, some states are lifting mandates wearing a mask such as the COVID-19 ban.
Biden described such steps as premature and dangerous.
