Coronavirus cases and deaths in the U.S. are continuing to fall to record-low levels even as the Indian 'Delta' variant spreads throughout the country.
On Sunday, the U.S. reported 3,892 infections of COVID-19, the lowest number since March 19, according to a DailyMail.com analysis of Johns Hopkins data.
What's more, the seven-day rolling average currently sits at 11,020, a 45 percent drop from the seven-day average reported three weeks ago.
COVID-19 deaths are also declining with 85 recorded on Sunday, the first time since the start of the pandemic that fewer than 100 fatalities have been reported in a single day.
The seven-day rolling average currently stands at 216, the lowest since since March 28 and a 66 percent drop the from the average three weeks prior.
Health experts say the improving numbers are because of COVID-19 vaccinations, with 65.4 percent of American adults receiving at least one dose and 55.8 percent fully vaccinated.
However, the Delta variant is spreading at rapid rates throughout Midwestern states including Iowa, Kansas, Missouri and Nebraska, which experts say could threaten to undo the progress the U.S. has made at reigning in the pandemic.

Experts are seeing an uptick in infections linked to the Indian 'Delta' coronavirus variant, B.1.617.2, and particularly in Midwestern states
As of Monday, the Delta variant makes up 10 percent of all cases in America - but it only made up six percent last week, meaning the prevalence almost doubled in just seven days.
Known as B.1.617.2, it has been labeled as a 'double mutant' by India's Health Ministry because it carries two mutations: L452R and E484Q.
L452R is the same mutation seen with the California homegrown variant and E484Q is similar to the mutation seen in the Brazilian and South African variants.
Both of the mutations occur on key parts of the virus that allows it to enter and infect human cells.
On Wednesday, the Missouri Department of Health and Senior Services released an advisory that the state 'is experiencing a rise in individuals contracting the Delta variant' and that it 'has become prevalent' throughout Missouri.
Missouri has the highest prevalence of the variant which makes up 6.8 percent of cases in the state as of May 22, CDC data show.
Current estimates suggest the prevalence could be as high as 23 percent.
In Greene County - 150 miles south of Kansas City- 90 percent of cases are linked to the Delta variant, an increase from 70 percent in mid-May.
'It shows us that what we've got in the community is a much more infectious variant that we are having to deal with, which shows why we have such an explosion of cases..in
