Coronavirus latest: 'Largest mass fatality incident' in New York City: Report

Week-over-week comparisons show the number of new COVID-19 cases and the number of new deaths are both increasing in the United States, according to an internal memo from the Federal Emergency Management Agency obtained by ABC News on Thursday night.

Eleven U.S. states and territories are in an upward trajectory of new cases, while 12 jurisdictions are at a plateau and 32 others are going down, the memo said.

There were 269,769 new cases confirmed across the nation during the period of Sept 10-16, a 5.3% jump from the previous week. Meanwhile, 6,015 coronavirus-related deaths were recorded during that same period, a 16.3% increase compared with the seven days prior, according to the memo.

The national positivity rate for COVID-19 tests ticked downward slightly to 4.5%, compared with 5.1% for the previous week, the memo said.

FEMA maps and charts also show a number of emerging COVID-19 hotspots in Wisconsin, which reported a record-breaking 2,034 new cases on Thursday.

Meanwhile, in Arkansas, 12.9% of new cases on Sept. 11 were attributed to colleges and universities. Half of all cases in the state are individuals aged 18 to 44, according to the memo.

In Florida, data released by the state health department shows that cases among children younger than 18 have increased by 26% since schools reopened for in-person instruction a month ago. The northern city of Gainesville reported a 91% relative increase in new cases during the period of Sept. 7-13, compared to the seven days prior. The spike was linked to outbreaks among sports teams and other students at the University of Florida, where the COVID-19 test positivity rate stands at 27.1%, the memo said.

In Indiana's Monroe County, new cases increased by a relative rate of 61.9% during the period of Sept. 7-13, compared to the previous week. The surge continues to be driven by Indiana University's campus in Bloomington, where fraternity and sorority housing had a COVID-19 test positivity rate of 24.56% for the week ending Sept. 11, according to the memo.

There were 44,360 new cases of COVID-19 identified in the United States on Thursday, according to a real-time count kept by Johns Hopkins University.

Thursday's tally is well below the country’s record set on July 16, when there were 77,255 new cases in a 24-hour-reporting period.

An additional 870 coronavirus-related fatalities were also recorded Thursday, down from a peak of 2,666 new fatalities reported on April 17.

A total of 6,675,564 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 197,643 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C. and other U.S. territories as well as repatriated citizens.

By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 70,000 for the first time in mid-July. The daily tally of new cases has gradually come down since then.

India confirmed another 96,424 COVID-19 cases and 1,174 more fatalities in the past 24 hours.

The daily case count is just under the world record that India had set the previous day of 97,894 COVID-19 cases confirmed within a 24-hour reporting period. The country's cumulative total now stands at more than 5.21 million cases with 84,372 deaths, according to the latest data from the Indian Ministry of Health and Family Welfare.

India has the second-highest tally of COVID-19 cases in the world and the third-highest death toll in the coronavirus pandemic, according to a count kept by Johns Hopkins University. However, based on the current rate of infection, India is expected within weeks to become the pandemic's worst-hit nation, surpassing the United States, where more than 6.6 million people have been diagnosed with COVID-19.

India has reported more than 1 million cases this month alone, which the health ministry has attributed to increased testing. The vast country of 1.3 billion people is conducting more than 1 million COVID-19 tests per day.
