Coronavirus updates: Trump can return to 'public engagements' Saturday, doctor says

An internal memo from the Federal Emergency Management Agency obtained by ABC News on Wednesday night shows that the number of new COVID-19 cases recorded in the United States and the nationwide usage of intensive care units are both on the rise in week-over-week comparisons.

There were 306,965 new cases confirmed during the period of Sept. 30-Oct. 6, a 4.8% increase from the previous week. There were also 4,860 coronavirus-related fatalities recorded during the period of Sept. 30-Oct. 6, a 4.6% decrease compared with the week prior, according to the memo.

Meanwhile, the national positivity rate for COVID-19 tests increased from 4.5% to 5.4% in week-to-week comparisons. Currently, 23% of hospitals across the country have more than 80% of beds full in their intensive care units. That figure was 17-18% during the summertime peak, the memo said.

The memo, which is circulated to the highest levels of the federal government and is used to determine daily priorities for the agencies working on COVID-19 response, shows that 32 U.S. states and territories are in an upward trajectory of infections, while 8 jurisdictions are at a plateau and 16 others are in a downward trend.

In Florida, 75% of ICU beds statewide are occupied. The number of new COVID-19 deaths doubled in Duval County in week-to-week comparisons, while Sumter County recently reported a single-day positivity rate for COVID-19 tests of over 20%, according to the memo.

Kentucky reported its highest single-day rise in COVID-19 cases on Oct. 3. Nearly half of current cases in northern Kentucky are patients younger than 40, and approximately 40% of them are under 30. The total number of COVID-19 hospitalizations has been increasing statewide since the end of September, the memo said.

The seven-day COVID-19 hospitalization rate continues to rise in Minnesota, reaching its highest since June 1 at 9.8 per 100,000 population, according to the memo.

In Ohio, the number of new COVID-19 cases has more than doubled in Muskingum County between the weeks ending Sept. 27 and Oct. 4. Outbreaks have been discovered at four social clubs there, according to the memo.

Wisconsin's seven-day COVID-19 death rate has increased 139% from Sept. 27 to Oct. 4. The seven-day COVID-19 hospitalization rate also continues to climb, with Wisconsin reporting a peak of 16.4 per 100,000 population on Oct. 4. The state saw a record high of 782 COVID-19 hospitalizations on Oct. 5, more than double the amount a month earlier. As of Oct. 4, 84% of ICU beds statewide were in use. Local health departments in the counties of Fox Valley, Door and Manitowoc report seeing so many new cases that they are unable to conduct tests or contact tracing in a timely manner, the memo said.

There were 50,341 new cases of COVID-19 identified in the United States on Wednesday, according to a real-time count kept by Johns Hopkins University.

The latest daily tally is up by nearly 10,000 from the previous day but is still under the country’s record set on July 16, when there were 77,255 new cases in a 24-hour-reporting period.

An additional 915 coronavirus-related fatalities were also recorded Wednesday, down from a peak of 2,666 new fatalities reported on April 17.

A total of 7,550,731 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 211,834 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 but has hovered around 40,000 in recent weeks.

The Czech Republic identified 5,335 new cases of COVID-19 on Wednesday, its highest single-day rise yet.

It's the first time the central European nation has registered more than 5,000 new cases in one day. The previous record of 4,457 new cases in a 24-hour reporting period was just set the day before.

The cumulative total now stands at 95,360 confirmed cases with 829 deaths, according to the latest data from the Czech health ministry.

More than 43,000 cases were active Wednesday, including 1,563 patients who remained hospitalized for COVID-19, while over 50,000 have recovered from the disease, according to the health ministry data.

The Czech Republic has the highest rate of COVID-19 infection in Europe. Over the past two weeks, the country of 10.7 million people has reported 346.1 cases per 100,000, surpassing Spain for the first time, which has seen 305 cases per 100,000, according to data published Tuesday by the European Center for Disease Prevention and Control.

Earlier this week, the Czech government declared another state of emergency due to the rapid increase in COVID-19 infections, after having relaxed almost all restrictions over the summer. The government is expected on Friday to announce new measures to contain the outbreak.

The Czech Republic is among a handful of European countries, including France, Spain and the United Kingdom, that are grappling with an uptick in COVID-19 cases as a second wave of infections hits the region.
