US coronavirus: Get tested if you socialized over Labor Day, Dr. Deborah Birx said
People who let down their guard and got too close to others over Labor Day weekend should get tested for Covid-19, White House coronavirus task coordinator Dr. Deborah Birx said.
Much of the coronavirus spread by people who don't have symptoms is happening between and within families and in settings such as neighborhood parties, Birx said Thursday at a media briefing at the University of South Carolina.
People who socialized closely with others, especially without a mask, should get tested, Birx said.
"Just because we know someone, we think that there's no way that they could have Covid, but I want to tell you, you can't tell," said Birx.
"We really encourage all of you to continue to get tested when you've had that kind of exposure, so we can stop community spread," she added.
"Our nature is to want to be with others and socialize," Birx told reporters. "What we're asking people to do is to socialize smart."
In the study, adults who tested positive for Covid-19 were about twice as likely to have reported dining at a restaurant in the 14 days before becoming ill than those who tested negative.
"Reports of exposures in restaurants have been linked to air circulation. Direction, ventilation, and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance," researchers wrote.
"Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use."
Universities and colleges in all 50 states report cases
More than 40,000 Covid-19 infections have been reported among students, faculty and staff at colleges and universities nationwide. The number represents cases that CNN has reported so far -- with the actual tally likely higher due to a lag from schools that update their data every few days.
With social life trickling back to life on campuses, outbreaks have hit places students congregate, such as fraternities and sororities, where some have continued to gather despite remote learning.
A cluster of Covid-19 cases was linked to a fraternity party at the University of New Hampshire. More than 100 people attended the August 29 event and few wore masks. Eleven people connected to the party have tested positive for the virus, university officials said.
The University of Wisconsin-Madison is directing all undergraduate students to restrict their movements for the next two weeks in an attempt to reverse the rise in Covid-19 cases.
In a memo to students, faculty and staff this week, Chancellor Rebecca Blank called on students to severely limit in-person interactions and stay in their residences except for essential activities. The university directed nine campus fraternities and sororities with off-campus live-in houses to quarantine for at least 14 days.
Illinois' Bradley University on Tuesday told all of its more than 4,500 students to quarantine in their on-campus or off-campus residences for two weeks, and to attend only online classes during that time, with allowances for meal pickups and other errands.
Though the school had less than 50 positive cases on campus, those cases led to 500 people being put in quarantine, so the school said it decided to have everybody reset.
Some of the highest number of cases are at Miami University, University of South Carolina, Ohio State University and East Carolina University, all of which have over 1,000 confirmed cases. The University of Missouri has 862 confirmed cases while Missouri State University has 791, a CNN tally shows.
While most students will likely recover, health experts have expressed concern that young people would spread the virus to the more vulnerable in their communities.
Experts stress importance of flu vaccine during coronavirus pandemic
A large concern is that the US could see the "perfect storm of accelerated Covid-19 activity, as people gather more inside, in particular -- as they become continually fatigued with the mask wearing, the social distancing, and the hand hygiene, and as they are exposed to seasonal influenza," Dr. Jeanne Marrazzo said Thursday.
Marrazzo, director of the Division of Infectious Diseases at the University of Alabama at Birmingham, made the comment during a briefing by the Infectious Diseases Society of America.
"If there was ever a naysayer, someone who's never been vaccinated (for flu), now's the time to rise," Dr. Leonard Mermel, medical director for the Department of Epidemiology and Infection Control at Rhode Island Hospital, said at the same briefing.
"Get the vaccine and reduce the risk of having these two life-threatening viruses infect you at the same time, or infect one of your loved ones," he said.
For now, rates of new daily coronavirus infections reported nationwide have been dropping after a summer surge.
The seven-day average of new daily reported infections in the US was about 35,300 as of Wednesday, down from a peak average of 67,317 on July 22, according to Johns Hopkins University data.
The country's Covid-19 death rate also has dipped. The seven-day average of new daily deaths was 734 Wednesday, after it was above 1,000 from late July to August 20, JUH data show.
Cases aren't falling in every state. West Virginia Gov. Jim Justice said Wednesday that his state's statistics were "getting worse by the day," and urged residents to do more to combat the spread.
West Virginia's seven-day average of new daily cases was 165 on Wednesday, up from around 100 at the end of August and around 50 at the start of July.
"This situation right now is really critical," Justice said.
Giroir says he's 'never been told to slow down testing'
The coronavirus testing lead for the White House coronavirus task force said Thursday that he has never been told to slow testing, and the country is continuing to increase its testing capacity.
"I have never been told to slow down testing, or to reduce our efforts -- and in fact, we built on testing every single month," Adm. Brett Giroir, a physician and the assistant secretary for health at the US Department of Health and Human Services, told CNN's Dr. Sanjay Gupta during a Research! America forum.
His comments come a day after experts said the US should be performing as many as 200 million Covid-19 tests every month to have any chance of controlling the pandemic. That report, from the Rockefeller Foundation and the Duke-Margolis Center for Health Policy, said fewer than 30 million tests are currently reported monthly in the country.
Giroir said that "this month, we should have the availability of over 100 million tests, and between 55% and 60% of those -- that's 55 to 60 million -- will be rapid point of care."
"This really puts us at an inflection point that we can really protect the elderly, we could protect the vulnerable, and we can do those kinds of screening testing for schools and work that we've been talking about for months now we have the tools to do that," Giroir told Gupta.
Doctor expresses fury about 'misinformation'
A frontline doctor is among those expressing fury over revelations that President Donald Trump downplayed the deadly threat from coronavirus early in the pandemic.
In a series of interviews, Trump told investigative reporter Bob Woodward that he downplayed the danger because he didn't want people to panic.
Dr. Craig Spencer, the director of Global Health in ER Medicine at NY-Presbyterian/Columbia University Medical Center, expressed his anger at the disclosure.
"I'm furious because you want to talk about panic and wanting to reduce panic -- I think of the panic of every single family I called on FaceTime to let them know their family member was dying or had died," Spencer told CNN's Anderson Cooper on Wednesday. "And I think about that multiplied by 190,000 times around this country."
It's "almost impossible" for health professionals to keep up with and correct the President's misinformation, he said.
