The U.S. has surpassed another bleak marker in the COVID-19 pandemic, as the country has reached 10 million confirmed cases of the virus, according to a database kept by Johns Hopkins.The milestone comes just hours after global cases surpassed 50 million, meaning about one out of every five people around the world diagnosed with the virus since the pandemic began has been diagnosed in the U.S.At least 237,000 Americans have died of the virus since the pandemic began. The U.S. continues to lead the world in both total cases and in deaths linked to the virus.The U.S. surpassed its 10 millionth case as the country deals with a disturbing spike in infections ahead of the winter months. The country surpassed 120,000 new cases in a single day three times last week, obliterating previous records. Prior to last week, the most confirmed cases the U.S. had seen in a single day was 102,000.The U.S. has recorded a million new cases of COVID-19 in the last 10 days alone. The country surpassed the 9 million case plateau on Oct. 30.In addition to the spike in cases, hospital resource use is also on the rise, and deaths linked to the virus are up slightly in recent days, though the death rate is not near what it was in March and April. Johns HopkinsHealth experts have warned that the U.S. is currently in a perilous position in the pandemic, with transmission rates as high as they have ever been as Americans move social gatherings indoors for winter months.In a memo last week, Dr. Deborah Birx — a member of the White House coronavirus task force — warned that the country is entering "the most deadly and concerning" phase of the pandemic.Late last month, Dr. Anthony Fauci — a member of the White House coronavirus task force and the county's top expert on infectious diseases — warned that the U.S. was in for a "whole lot of pain" if things didn't change soon.The U.S. did get some good news in the pandemic on Monday, as Pfizer announced that its vaccine candidate has been 90% effective in promoting immunity against the virus. However, even if the vaccine were to get FDA approval in the next few days, it would still take several months for most of the country to be vaccinated — and officials fear that vaccine skepticism could keep immunity levels below the threshold to stifle the virus. 2314

The United States plans to end enhanced health screening of travelers from certain countries next week, and those visitors will no longer be funneled through 15 large U.S. airports.Those requirements were imposed in January to prevent the spread of COVID-19. The Centers for Disease Control and Prevention said the government will remove those edicts beginning Monday.The CDC said the current screening, which includes temperature checks and questioning travelers about COVID-19 symptoms, “has limited effectiveness” because some infected people have no symptoms or only minor ones. Travelers go through customs only after the health screening.The health agency said that of the 675,000 travelers who went through the process, fewer than 15 were found to have COVID-19 because of the extra screening.The health agency said that instead it will focus on other measures, including a stronger response to reports of illness at airports, collecting passenger-contact electronically to avoid long lines, and “potential testing to reduce the risk of travel-related transmission” of the virus.The extra health screening applies to people who have been in China, Iran, most countries in continental Europe, the United Kingdom, Ireland and Brazil. Most people coming from those countries who aren’t U.S. citizens have been barred entry to the country.The Homeland Security Department did not immediately respond to a request for comment Thursday.A trade group representing the nation’s largest carriers praised the change.“We continue to support spending scarce screening resources where they can best be utilized,” Airlines for America said in a statement Thursday, “and, given the extremely low number of passengers identified by the CDC as potentially having a health issue, agree that it no longer makes sense to continue screening at these airports.”Separately, 18 travel and airline groups asked the administration to start pre-flight virus testing as a way to reopen international travel. The groups argue that more screening could allow countries to lift travel restrictions and quarantines that have shut down most travel between the U.S. and Europe.Airlines including Delta and Southwest have lobbied the Transportation Security Administration to screen passengers for fever before allowing them on flights within the United States. However, the CDC questioned the usefulness of temperature screening because of the large number of infected people who do not have fevers, and no widespread screening of domestic passengers was launched.___This story has been updated to read that screening began at some airports in January, not February.___This story has been corrected to note that the COVID-19 health screening began at some airports in January, not February. 2771

The Trump administration on Thursday imposed penalties on 17 individuals over their alleged roles in the killing of dissident journalist Jamal Khashoggi.The fresh sanctions from the Treasury Department come hours after Saudi prosecutors said they would seek the death penalty for five people charged in the death of Khashoggi, who was a contributor to The Washington Post."The Saudi officials we are sanctioning were involved in the abhorrent killing of Jamal Khashoggi," said Treasury Secretary Steven Mnuchin in a statement. "These individuals who targeted and brutally killed a journalist who resided and worked in the United States must face consequences for their actions."The secretary said the US government would work "diligently" to obtain all the facts on the death of Khashoggi and hold "accountable" any individual found responsible."The Government of Saudi Arabia must take appropriate steps to end any targeting of political dissidents or journalists," he said.Mnuchin had previously told reporters it would be "premature" to discuss whether the US would impose sanctions on the Saudi government.Earlier on Thursday, the Saudi Public Prosecutor's office said a total of 11 people were charged, adding that the five people facing capital punishment were directly involved in "ordering and executing the crime."The prosecution also shared details of the journalist's murder, saying Khashoggi was killed on October 2 following "a fight and a quarrel" at the Saudi consulate in Istanbul. Prosecutors say Khashoggi was tied up and injected with an overdose of a sedative that killed him, then his body was chopped up and given to a local collaborator. 1668

The world's biggest COVID-19 vaccine test got underway Monday with the first of 30,000 planned volunteers. The experimental vaccine is made by the National Institutes of Health and Moderna Inc. It's one of several candidates in the final stretch of the global vaccine race. Officials are seeking to find out whether more people who get dummy shots become infected than those given two doses of the real vaccine. The U.S. government plans separate huge studies of several leading vaccine candidates through fall, each in hot spots where the virus still is spreading.Dr. Anthony Fauci and other Trump administration officials have said that the company is already producing millions of doses of the vaccine in the event that it receives Emergency Use Authorization from the FDA following the trial. Fauci remains cautiously optimistic that a vaccine could be available by January of next year — though it's unclear how long it would take for a vaccine to be available for all Americans who want it. 1004

The Trump administration is considering a new travel ban to replace its original executive order, which has had its legality questioned and is up for a Supreme Court hearing next month, White House national security adviser H.R. McMaster said Sunday."Well, this is something that we're looking at, is how to protect the American people better, how to ensure that we know who these people are who are moving," McMaster told George Stephanopoulos on ABC's "This Week."This renewed discussion of the travel ban comes after Friday morning's terrorist attack in London, in which 30 passengers on a London Underground train were injured after a bomb went off.In a tweet Friday in response to the attack, President Donald Trump called for a "larger, tougher and more specific" travel ban and also called for shutting down terrorist group's use of the internet for indoctrination and recruitment.McMaster echoed the point Sunday."Because of the strength of these terrorist organizations -- why this is a greater danger than ever -- is, first of all, their ability to communicate, to connect what would otherwise be disconnected cells in other places in the world," he said. "The second part of this is their ability to travel and to move and to move people and money and weapons, oftentimes drugs and other illicit goods, internationally. So part of the strategy must be to interdict these networks, interdict them from how they use information, and communicate, but how they move physically, as well.The Supreme Court is set to hear?oral arguments in the travel ban case early next month.The President's executive order would suspend travel from six Muslim-majority countries (Iran, Libya, Somalia, Sudan, Syria and Yemen) for 90 days while the secretary of homeland security and others submit a report on the results of a worldwide review to identify what additional information will be needed from each country to make sure an individual seeking entrance is not a public-safety threat.Responding to a lawsuits from states challenging the ban, the Supreme Court let much of the ban take effect in late June, meaning the 90-day clock started and will hit on or around September 24.Administration officials have not divulged the specifics of their future plans.At a recent homeland security conference in Washington DC, acting Customs and Border Protection Deputy Commissioner Ronald Vitiello said, "We are in the process of action planning about each of the opportunities that the US government has to interview and/or vet potential inbound travelers."That could include "looking at things like social media, looking at things like smart phones, those kinds of windows, if you will, into people's backgrounds and their activity," he said.The-CNN-Wire 2771
