沈阳皮肤过敏该如何治疗(沈阳治正规荨麻疹要多少钱) (今日更新中)

The Centers for Disease Control has issued new guidance for employers, giving them various situations they may come across and how they should decide to test their employees for COVID-19."There's a lot of different questions coming out from employers about the whole process of testing, doing temperature taking of employees who are returning back to work again," says Amber Clayton, the knowledge center director at the Society for Human Resources Management.Clayton says employers are grappling with increased uncertainty surrounding how and when to implement coronavirus testing at their offices."Employers can have a policy in place. Per the Equal Employment Opportunity Commission they can test during this pandemic so they could require COVID testing. Now, antibody testing can’t be mandated but COVID testing can," says Clayton.The CDC recommends, in most cases, to only test employees who are showing symptoms.But what if a person knows they've been exposed to the virus but isn't showing symptoms, is a test appropriate?"I think it may be on a case by case basis. So, if it is positive, I think it's probably helpful. It tells you the person did in fact become infected," says Dr. Beth Thielen, an infectious disease doctor with the University of Minnesota.Dr. Thielen says employers should be careful, though, as employees who aren't showing symptoms could have a false negative if they test too early, before the virus spreads in the person's system."The CDC guidance still indicates if someone tests positive for COVID before they return back to work, they should be quarantined and out of work for at least 10 days, that they don't have a fever or they've they have gone without a fever for 24 hours or without fever reducing medications," says Clayton.Employers can ask employees who have gotten a positive COVID-19 test to take a second test, showing they're negative before returning to work, but the CDC doesn't recommend it and says in their guidelines, "Employees with COVID-19 who have stayed home can stop home isolation and return to work when they have met one of the sets of criteria.”Some of that criteria includes 10 days passing since the employee last experienced any COVID-19 symptoms.Dr. Thielen says, this recommendation makes sense."We haven’t detected people who have had culturable virus out as far as 14 days after," says Dr. Thielen. She adds, so far, studies have found that most people who still test positive weeks alter won't transmit the virus to others. She believes employers should continue to look to the CDC for guidance."I think these are some of our leading public health thinkers and they’re making decisions based on a long history of experience based on dealing with other respiratory infections but also newly emerging data," says Dr. Thielen.As for Clayton, she says employers will want to ensure the confidentiality of employees who do test positive while at the same time notifying others who may have been exposed. And also, do some research or consult legal counsel before implementing any testing at the office."Or if you have situations where employees refuse to be tested maybe for medical reasons, those things tend to fall under the Americans with Disabilities Act sometimes, so make sure you’re doing your homework before you implement any type of testing program," says Clayton. 3350

The Food and Drug Administration on Wednesday authorized the first rapid coronavirus test that doesn’t need any special computer equipment to get results.The 15-minute test from Abbott Laboratories will sell for , giving it a competitive edge over similar tests that need to be popped into a small machine. The size of a credit card, the self-contained test is based on the same technology used to test for the flu, strep throat and other infections.It’s the latest cheaper, simpler test to hit the U.S. market, providing new options to expand testing as schools and businesses struggle to reopen and flu season approaches. The FDA also recently greenlighted a saliva test from Yale University that bypasses some of the supplies that have led to testing bottlenecks.Both tests have limitations and neither can be done at home. Several companies are developing rapid, at-home tests, but none have yet won approval. Abbott’s new test still requires a nasal swab by a health worker, like most older coronavirus tests. The Yale saliva test eliminates the need for a swab, but can only be run at high-grade laboratories.And in general, rapid tests like Abbott’s are less accurate than lab-developed tests. The FDA said in a statement announcing the decision that negative results with Abbott’s test may need to be confirmed with a lab test in some cases. The agency granted Abbott’s test an emergency use authorization late Wednesday for patients with suspected COVID-19.The two additions should help expand the number of available tests. The U.S. is now testing about 690,000 people per day, down from a peak of 850,000 daily tests late last month. Many public health experts believe the country will soon need to test vastly more people to find those who are infected, isolate them and contain the virus.The FDA noted that Abbott’s test could be used in a doctor’s office, emergency room or some schools. “Given the simple nature of this test, it is likely that these tests could be made broadly available,” the FDA said.Since the start of the pandemic, nasal swab tests that are sent to a lab have been the standard for COVID-19 screening. While considered highly accurate, the tests rely on expensive, specialized machines and chemicals. Shortages of those supplies have led to repeated delays in reporting results, especially during a spike in cases last month.Government and health experts view rapid tests that can be run outside the laboratory system as key to boosting capacity.“Those screening tests are what we need in schools, workplaces and nursing homes in order to catch asymptomatic spreaders,” said Dr. Jonathan Quick of the Rockefeller Foundation, in an interview earlier this month. The nonprofit group has called for the U.S. to conduct about 4 millions per day by October, mostly rapid, point-of-care tests.Abbott’s BinaxNOW is the fourth rapid test that detects COVID-19 antigens, proteins found on the surface of the coronavirus, rather than the virus itself. It’s considered a faster, though sometimes less precise, screening method. The other tests need to be inserted into a small machine.Inside the Abbott test is a specially coated strip that interacts with COVID-19 antigens. The patient’s nasal swab is inserted into the card and a few drops of a chemical solution are added. Markings appear on the card to indicate whether the sample is positive or negative — much like a pregnancy test.Two other makers of antigen tests — Quidel and Becton Dickinson have said they haven’t been able to meet demand for the tests. A third, LumiraDx, plans to begin shipping its recently approved antigen tests by the end of this month. Abbott expects to begin shipping tests in September, reaching 50 million tests a month in October.The influx of antigen tests will go a long way toward meeting the Trump administration’s projection that 90 million COVID-19 tests a month will be available by September if needed. But U.S. “testing czar” Adm. Brett Giroir has stressed that the U.S. can contain the outbreak with far fewer tests.“That’s the capacity ... we do not need that many tests to safely and sensibly reopen,” Giroir told reporters on a recent call. He pointed to several key indicators that have been falling, including new infections and hospitalizations, even as testing has slowed.Earlier this month, the FDA authorized Yale’s saliva-based test, which is expected to cut the time and cost compared with similar tests. It’s the fifth COVID-19 saliva tests OK’d by regulators. All require lab processing.Developed by Yale’s School of Public Health, SalivaDirect can use any sterile container to collect a sample, not the special tube needed with earlier tests, and requires less chemicals. Outside experts welcomed the new approach but noted its limitations.“It’s not a rapid test, it’s a laboratory-based test that will still be prone to the same massive delays as any other test,” said Dr. Michael Mina of Harvard University.___Follow Matthew Perrone on Twitter: @ AP_FDAwriter.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The Department of Justice announced Wednesday the indictment of two fighters affiliated to the Islamic State group who are alleged to have killed American journalists and aid workers.El Shafee Elsheikh and Alexanda Kotey were previously in U.S. military custody in Iraq and have been transported to Virginia to face trial.Elsheikh and Kotey, both of the United Kingdom, are two of the four ISIS fighters nicknamed "The Beatles" by intelligence officers because of their British accents. They've been linked to the killings of aid workers Peter Kassig and Kayla Mueller and journalists Steven Sotloff and James Foley.“These charges are the product of many years of hard work in pursuit of justice for our citizens slain by ISIS. Although we cannot bring them back, we can and will seek justice on behalf of their memories,” Attorney General William Barr said in a statement. “My message to other terrorists around the world is this — if you harm Americans, you will face American arms on the battlefield, and if you survive that ordeal, you will face American law in our courtrooms with the prospect of many years in an American prison. Either way, you will never live in peace — you will be pursued to the ends of the earth until justice is done.”Barr was not present at Wednesday's press conference as he is currently self-isolating amid a COVID-19 outbreak in the Trump administration. 1395

The Cumberland, Wisconsin High School Class of 2018 got a special shout out from the local police department on an epic senior prank.The police department said on Facebook it was "one of the best senior pranks that Cumberland High School has seen."Students positioned an old junker strewn with loose bricks in front of what appeared to be a gaping black hole in the building's side, just outside the principal's office.It wasn't actually a hole, though. Using tape and a black tarp, the students created the illusion of damage, making it look like the car crashed into the side of the building. The back of the car said, "CHS Class of 2018."The best part? This prank included absolutely no damage at all to school property, which is why police singled it out."Hats off to the Cumberland High School Class of 2018 on your senior prank...Congratulations to all the seniors who are graduating," police said.This isn't the first time the tiny town of Cumberland has been in the viral spotlight. In fact, it's not even the first time this year.Back in January, the school district enlisted the help of former Backstreet Boys star AJ McLean to announce a snow day."Hey there Cumberland Beavers," McLean says in the video. "It's AJ from the Backstreet Boys. I hear you guys have some pretty nasty weather out there today. yeah, It's a snow day and here to 'tell you why' is Mr. Narges and the entire administrative team.""You're having a snow day," AJ sings.  It is unclear how the Cumberland school district got McLean's help, but the video canceling classes for the day caught the attention of people around the country -- it has since racked up nearly 70,000 views on YouTube. 1710

The Environmental Protection Agency blocked reporters from several news outlets from a national summit on Tuesday where Scott Pruitt, the agency's chief, was speaking.Journalists from CNN, the Associated Press and the trade publication E&E were barred by the EPA from entering the event, which was focused on harmful chemicals in water. A handful of other reporters from other news organizations, however, were allowed inside the event after having been previously invited by the agency.In a statement, Jahan Wilcox, an EPA spokesman, said the agency barred reporters from attending due to space limitations inside the venue. He said the EPA was able to accommodate only 10 reporters and that it provided a livestream "for those we could not accommodate.""This was simply an issue of the room reaching capacity, which reporters were aware of prior to the event," Wilcox said.A report published by The Hill, however, said a handful of seats in the press section remained vacant by the time Pruitt began speaking. A photo obtained by CNN also showed space for cameras.Additionally, the Associated Press said in a story that one of its reporters, denied entry, was grabbed by security guards and forcibly shoved out of the building after asking to speak to an EPA public affairs person. A CNN photographer saw the Associated Press journalist being shoved out of the building by a uniformed guard, and the Associated Press journalist recounted the incident to CNN immediately after it took place.When reached by phone and asked about the Associated Press report, Wilcox declined to comment to CNN beyond his original statement, which said he was "unaware of the individual situation that has been reported."CNN was also blocked from attending the summit. A CNN photographer was screened by security guards before the event and was waiting for an escort or further information. Wilcox arrived soon after and provided security with a list of news outlets and reporters, instructing them not to let anyone not on the list into the event. The CNN photographer then asked if he could enter the event and was told by security he couldn't.Separately, a CNN reporter and producer lined up with members of the public and presented their IDs and credentials, identifying themselves as reporters. The individual manning the door said he needed to ask the press office if they could be permitted to enter. A few minutes later, he returned and said the CNN journalists were not allowed in.In a statement, a CNN spokesperson said, "Today, CNN was turned away from covering the PFAS National Leadership Summit at the EPA after multiple attempts to attend. While several news organizations were permitted, the EPA selectively excluded CNN and other media outlets. We understand the importance of an open and free press and we hope the EPA does, too."Sally Buzbee, executive editor of The Associated Press, said in a separate statement, "The Environmental Protection Agency's selective barring of news organizations, including the AP, from covering today's meeting is alarming and a direct threat to the public's right to know about what is happening inside their government."Buzbee added, "It is particularly distressing that any journalist trying to cover an event in the public interest would be forcibly removed."The-CNN-Wire 3320
