narvikk/iStockBy MORGAN WINSOR and EMILY SHAPIRO, ABC News(NEW YORK) — A pandemic of the novel coronavirus has now killed more than 968,000 people worldwide.Over 31.4 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The criteria for diagnosis — through clinical means or a lab test — has varied from country-to-country. Still, the actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.Since the first cases were detected in China in December, the virus has rapidly spread to every continent except Antarctica.The United States is the worst-affected country, with more than 6.8 million diagnosed cases and at least 200,768 deaths.California has the most cases of any U.S. state, with more than 791,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 735,000 cases and over 687,000 cases, respectively.Nearly 170 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least six of which are in crucial phase three trials.Here’s how the news developed Tuesday. All times Eastern:Sep 22, 9:00 pmCOVID-19 cases up 15%, according to FEMA New COVID-19 cases increased nationally over the last week, according to an internal FEMA memo obtained by ABC News.In the last seven days, new cases went up 15.1% compared to the previous seven days, the memo said.Cases are going up in 22 states and territories, with Colorado in particular seeing a “sharp uptick” in cases last week “primarily related to institutions of higher education,” the memo noted. Within Colorado, the counties of Denver, Adams and Boulder had the highest number of new cases over the last three weeks, according to the memo. Boulder County — home to the University of Colorado-Boulder — reported the largest number of cases last week, it said.Wisconsin is also seeing a surge in cases tied to college campuses. Over 80% of all counties in the state have moderate or high levels of community transmission, according to the memo, and a large proportion of the localities with the fastest-growing epidemics have a University of Wisconsin campus. Last week, the University of Wisconsin-Madison reported more than 700 cases, the memo said. Eighteen- to 24-year-olds have a case rate five times higher than any other age group in the state, FEMA found.Deaths due to COVID-19 were stagnant nationally, according to the memo. In the last week, there was a 0.6% decrease in recorded deaths over the previous week. Virginia had its second-worst week of reported deaths last week, with 238, including the first COVID-19 death in a child in the state, the memo said.The national test-positivity rate ticked downward slightly in the past seven days, to 4.4%, said the memo. It was 4.6% for the prior seven-day period.Sep 22, 2:52 pmNorth Carolina outdoor event venues can soon open at very limited capacityIn North Carolina, larger outdoor event venues can reopen at 7% capacity on Oct. 2., Gov. Roy Cooper said Tuesday.The state’s positive test percentage has been dropping and is now between 5 and 6%, state officials said.Meanwhile, North Carolina’s Department of Health and Human Services announced a new contact tracing app called “SlowCOVIDNC.”The app will alert people “when they may have been exposed to someone who has tested positive for COVID-19,” the Department of Health and Human Services said Tuesday. “It is completely anonymous and does not collect, store or share personal information or location data.”Sep 22, 12:30 pmWisconsin declares public health emergency due to ‘surge’ among young peopleWisconsin Gov. Tony Evers declared a public health emergency on Tuesday due to a “recent surge in cases among young people.”Eighteen to 24 year olds have a COVID-19 case rate five times higher than any other age group, according to the governor.“We are seeing an alarming increase in cases across our state, especially on campus,” Evers said in a statement. “We need folks to start taking this seriously, and young people especially—please stay home as much as you are able, skip heading to the bars, and wear a mask whenever you go out.”Wisconsin is “experiencing unprecedented, near-exponential growth of the COVID-19 pandemic,” the governor’s office said.On Aug. 31, the number of new daily cases reported in the state was at 678. On Monday, the number of daily cases reported was 1,791.Evers on Tuesday also issued a new face covering order requiring residents ages 5 and older to wear a mask indoors.Sep 22, 12:12 pmUS coronavirus death toll tops 200,000The novel coronavirus has now killed 200,000 people in the United States, just eight months after the nation’s first confirmed case.The U.S. death toll from COVID-19 currently stands at 200,005, according to a real-time count kept by Johns Hopkins University.The first case of the novel coronavirus in the United States was reported in a patient in Washington state on Jan. 20, according to the U.S. Centers for Disease Control and Prevention.Four months later, on May 27, the U.S. death toll reached 100,000.The novel coronavirus has now killed nearly twice as many Americans as the 116,516 who died in World War I, the third-deadliest conflict in the nation’s history. More than 400,000 Americans died in World War II, while an estimated 655,000 died in the Civil War.ABC News’ Marc Nathanson contributed to this report.Sep 22, 11:25 amAnalysis shows cases rising in at least 33 US statesAn ABC News analysis of COVID-19 trends across all 50 U.S. states as well as Washington, D.C. and Puerto Rico found there were increases in confirmed cases over the past two weeks in 33 states, the nation’s capital and the U.S. island territory in the Caribbean.The analysis also found increases in the daily positivity rate of COVID-19 tests in 16 states and Washington, D.C., increases in COVID-19 hospitalizations in 17 states as well as in D.C. and Puerto Rico, and increases in daily COVID-19 death tolls in 15 states as well as in Puerto Rico.The trends were all analyzed from data collected and published by the COVID Tracking Project over the past two weeks, using the linear regression trend line of the seven-day moving average.The nationwide rise in COVID-19 cases may be correlated to several factors. Although the increase may be partially related to Labor Day festivities, it may also be tied to the virus spreading to communities from outbreaks on college campuses.Moreover, the rise in new cases may be related to increasing mobility across states and communities. Several states, such as Idaho, North Dakota, South Dakota, Wisconsin and Utah, have seen a rise in mobility, according to a tracking tool created by Apple.ABC News’ Benjamin Bell, Brian Hartman, Soorin Kim and Arielle Mitropolous contributed to this report.Sep 22, 10:28 amTrump falsely claims COVID-19 ‘affects virtually nobody’As the U.S. death toll from COVID-19 approaches the 200,000 mark, President Donald Trump has falsely claimed that the novel coronavirus “affects virtually nobody.”He made the comments to a crowd of supporters Tuesday night during a campaign rally in Swanton, Ohio.“We now know the disease. We didn’t know it, now we know it. It affects elderly people — elderly people with heart problems and other problems. If they have other problems, that’s what it really affects — that’s it,” Trump claimed.“You know, in some states, [it affects] thousands of people — nobody young. Below the age of 18, like, nobody,” he continued. “They have a strong immune system, who knows. Take your hat off to the young because they have a hell of an immune system. But it affects virtually nobody. It’s an amazing thing.”Sep 22, 8:49 amUK prime minister says tough new restrictions could stay for six monthsBritish Prime Minister Boris Johnson on Tuesday unveiled a slew of tough new measures to curb the spread of COVID-19 in England, which he said may need to stay in force for six months.“I fervently want to avoid taking this step, as do the devolved administrations, but we will only be able to avoid it if our new measures work and our behavior changes,” Johnson told members of Parliament in the House of Commons. “We will spare no effort in developing vaccines, treatments, new forms of mass-testing. But unless we palpably make progress, we should assume that the restrictions that I have announced will remain in place for perhaps six months.”Johnson announced a 10 p.m. curfew for all hospitality venues in England starting Thursday. He said pubs, bars and restaurants throughout the country must also operate a table service only, except for takeaways.Meanwhile, the use of face coverings will be extended to include all users of taxis and private-hire vehicles, all staff in retail, and all employees and customers at indoor hospitality venues except when seated at a table to eat or drink. The prime minister warned that businesses could be fined if they break the new rules.Johnson also announced that, from Monday, there will be a 15-person limit on the number of attendees allowed at wedding ceremonies and receptions in England, as well as a 30-person cap for all funerals held in the country.While Johnson said that people who can work from home should again do so, he stressed that his government “will do everything in our power” to keep schools open and children in classrooms.The prime minister noted that the three other devolved governments of the United Kingdom — Northern Ireland, Scotland and Wales — would adopt similar measures.“For the time being, this virus is a fact of our lives,” he said, “and I must tell the House and the country that our fight against it will continue.”Sep 22, 7:44 amFormer acting CDC director: ‘When you lose trust you lose lives’The former acting director of the U.S. Centers for Disease Control and Prevention said Tuesday that the agency is losing the public’s trust by walking back its COVID-19 guidance.“The problem is, there have been so many instances where there’s been political fingerprints on CDC documents, and CDC hasn’t been able to be out front to explain what’s going on. It leads to an undermining of trust and when you lose trust, you lose lives,” Dr. Richard Besser, who is now the president and CEO of the Robert Wood Johnson Foundation, told ABC News chief anchor George Stephanopoulos during an interview on Good Morning America.The CDC recently issued and later removed updated guidance on its official website to address growing evidence of limited airborne transmission of the virus that causes COVID-19. The agency said Monday that posting the new information was done in error.“The CDC should be out there every day explaining what they’re learning, explaining why guidance is changing,” Besser said. “I talked to a leader at CDC and I expect very soon there will be guidance out that talks about other routes of transmission, like aerosols, and what can be done to reduce the risk of transmission as well.”As the U.S. death toll from COVID-19 edges closer to 200,000, Besser described the pandemic as the worst public health crisis in his lifetime and discussed the danger of downplaying the situation.“When you think about this loss of trust and loss of lives, you know, every community is affected but not equally. Black Americans, Latino Americans, Native Americans, low-income Americans are being hit the hardest,” he said. “So when people downplay the significance of this, there are certain groups that are really paying the price.”Besser warned that coronavirus-related restrictions may need to be rolled out again this winter as people spend more time indoors, increasing the risk of catching respiratory viruses.“Viruses do better in the winter,” he said. “That’s something people should anticipate.”Sep 22, 6:54 amUK prime minister to announce new restrictions for EnglandBritish Prime Minister Boris Johnson is expected Tuesday to announce new measures in England to curb an alarming rise in COVID-19 infections.Michael Gove, a senior member of Johnson’s cabinet, told Sky News that the clampdown will include ordering pubs and restaurants throughout England to close by 10 p.m. as well as restricting the entire hospitality sector to table service only. The government will also be encouraging people who can work from home to do so, reversing a push to get people back to the office, according to Gove.It’s unknown whether the new restrictions would ultimately be extended U.K.-wide, with coronavirus-related policy responsibilities delegated to the devolved administrations in Northern Ireland, Scotland and Wales.“They are reluctant steps that we’re taking,” Gove told Sky News in an interview Tuesday morning. “But they’re absolutely necessary because, as we were reminded yesterday and as you’ve been reporting, the rate of infection is increasing, the number of people going to hospital is increasing, therefore we need to act.”The move comes a day after the government’s chief scientific officer, Sir Patrick Vallance, warned that the United Kingdom could see about 50,000 new COVID-19 cases a day by mid-October if the current rate of infection is not curbed.Sep 22, 6:52 am23 US states and territories in an upward trend of new casesAn internal memo from the Federal Emergency Management Agency obtained by ABC News on Monday night shows that the number of new cases and the number of new deaths recorded in the United States are both increasing in week-over-week comparisons.Twenty-three U.S. states and territories are in an upward trajectory of COVID-19 infections, while 14 jurisdictions are at plateau and 19 others are in a downward trend, the memo said.There were 283,332 new cases confirmed across the nation during the period of Sept 14-20, a 17.2% jump from the previous week. Meanwhile, 5,319 coronavirus-related deaths were recorded during that same period, a 2.4% increase compared with the seven days prior, according to the memo.The national positivity rate for COVID-19 tests ticked downward slightly to 4.4%, compared with 4.6% for the previous week, the memo said.Alabama recorded a 46.5% increase in the state’s seven-day death rate during the period of Sept. 9-15, compared with the week prior. Meanwhile, the Alabama Hospital Association confirmed a statewide shortage of nurses in both hospitals and universities due to a lack of faculty, facilities and funds, according to the memo.In Florida’s Alachua County, 90% of recently reported cases are among individuals between the ages of 15 and 25, and 70% of those cases are college students, according to the memo.Meanwhile, a recent increase in new cases in Kentucky’s Hardin County is attributable to roughly 75% of students returning to school for in-person instruction, the memo said.New Jersey’s positivity rate for COVID-19 tests rose from 3% to 7% among 14-18 year-olds and from 2.7% to 7.1% among 19-24 year-olds. Nearly 20% of the state’s confirmed cases are individuals below the age of 30, according to the memo.Pennsylvania’s Centre County, home to Pennsylvania State University, remains a COVID-19 hotspot, reporting a 291.3% relative increase in new cases during the period of Sept. 9-15 compared with the previous week. The county’s hospitals are under strain, with inpatient beds at 88% capacity and intensive care unit beds at 81% capacity, the memo said.South Dakota reported its highest single-day death toll of eight coronavirus-related fatalities on Sept. 16. The state saw a 21% increase in COVID-19 hospitalizations, setting a record high on Sept. 15. A major outbreak in the state’s capital, Pierre, has led to at least 105 cases among inmates at a minimum-security women’s prison as well as rising cases among community members, according to the memo.Sep 22, 4:50 amUS death toll less than 200 away from hitting 200,000 markAn additional 356 coronavirus-related fatalities were recorded in the United States on Monday, bringing the country’s death toll even closer to the 200,000 mark, according to a real-time count kept by Johns Hopkins University.Monday’s tally of COVID-19 deaths is well under the country’s record set on April 17, when there were 2,666 new fatalities in a 24-hour reporting period.There were also 52,070 new cases of COVID-19 confirmed across the nation on Sunday, down from a peak of 77,255 new cases reported on July 16.A total of 6,857,967 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 199,884 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.Copyright © 2020, ABC Audio. All rights reserved.
