Test-to-stay: Instead of quarantine for Covid-exposed students, some schools are trying testing

  Test-to-stay: Instead of quarantine for Covid-exposed students, some schools are trying testing For test-to-stay, if Covid-exposed students test negative and have no symptoms, they can continue going to school in person. If the exposed student tests positive, they must isolate at home. This approach is called test-to-stay, and the US Centers for Disease Control and Prevention is now working with select school districts across the nation to evaluate the practice. Marietta City Schools told CNN that it originally implemented its test-to-stay program on its own; it's now one of the school districts in touch with the CDC as part of its evaluation process.

Why do the Covid 19 tests take so long for results when a nurse in our family took a test and had the results 3 hours later? There was supposed to be a testing kit that could give results in 5 -8 minutes, but no more has been reported about that. Most swabs/blood tests can take from around 15 hours to longer , depending how big the lab is, how many samples they are dealing with and so on. From what I have read, it is usually around 15 hours, but as usual, it is supposed to be getting faster, if only we were told ALL the information, and the follow ups, were more forthcoming, we would know for

Experts from companies, laboratories, and hospitals, along with top government officials, tell Fortune they are trying their best to cut down how long it takes to get a COVID test result back, including prioritizing tests for certain people and promoting technologies that can deliver results within 15 minutes.

In one recent week, a New Yorker got a free Covid-19 test in a jiffy, with results the next day, while a Coloradan had to shell out $50 for a test two cities from her hometown after a frantic round of pharmacy-hopping. A Montanan drove an hour each way to get a test, wondering whether, this time, it would again take five days to get results.

While Covid testing is much easier to come by than it was early in the pandemic, the ability to get a test — and timely results — can vary widely nationwide. A fragmented testing system, complicated logistics, technician burnout and squirrelly spikes in demand contribute to the bumpy ride.

NY man charged with felony, could face 7 years in prison after being accused of faking COVID-19 vaccine card

  NY man charged with felony, could face 7 years in prison after being accused of faking COVID-19 vaccine card A New York man was charged with showing his employer a plagiarized COVID-19 vaccine card. If convicted, he could face up to seven years in prison.David R. Kemp, 24, of Eaton, N.Y., was charged with a second-degree possession of a forged instrument, which qualifies for a Class D felony in the state. The unauthorized use of a government agency’s seal is a federal crime.

If you develop symptoms, get tested right away. Otherwise, wait five to seven days. COVID -19’s incubation period lasts up to 14 days. If you have the virus, it takes time to build up in your system. Early testing can result in samples that don’t contain enough of the virus’ genetic material to show a positive result . A COVID -19 test is limited in that it represents only a snapshot in time. A negative PCR test for COVID -19 does not mean that an individual is free of infection, but rather that, at that particular moment, the sample did not contain viral levels at a high enough concentration to be measured as a

Lateral flow tests (LFTs) are very good at detecting people most likely to spread Covid -19 and positive results should be trusted, say University College London researchers. When LFTs were introduced, they were criticised for being less accurate than PCR tests , which are analysed in a lab. One third of people with Covid can spread it while showing no symptoms. Based on the UCL research, Prof Irene Petersen, lead study author, said people who get a positive LFT result "should trust them and stay at home". But government guidance says people must get a follow-up PCR test after a positive LFT to

“We’re still where we were 18 months ago,” said Rebecca Stanfel, the Montana woman who had to wait five days for test results in Helena last month after she was exposed to someone with the virus.

Unpredictable waits can be a problem for those trying to plan travel, return to school from quarantine — or even get lifesaving monoclonal antibody treatment within the optimal window if they do have Covid.

The White House said this month that it plans to buy $1 billion worth of rapid antigen tests to help improve access to the hard-to-find over-the-counter kits. But people are also facing problems getting molecular testing, including the gold-standard PCR tests.

Public health labs are no longer hamstrung by supply bottlenecks for individual test components, such as swabs or reagents, said Kelly Wroblewski, the director of infectious disease programs for the Association of Public Health Laboratories. But they are still bearing large testing loads, which she had expected to shift more to commercial or hospital-based labs by now.

Over 25% of Americans are no longer living in high-transmission counties: Live COVID-19 updates

  Over 25% of Americans are no longer living in high-transmission counties: Live COVID-19 updates More than one-quarter of Americans are now living in a county that no longer has high levels of community transmission of coronavirus. COVID updates.That's a major change from earlier in the pandemic wave driven by the delta variant, when every state was considered to have high levels of community transmission, which the CDC says is 100 cases per 100,000 people per week.

I need to fly internationally and need to take a COVID -19 test 96 hours before my flight. The only place where I can get tested without any symptoms … Has gotten tested at Rite Aid in Atascadero and how long did it take for you to get back the results ?

Voting does nothing, why do you think there were so many murders in the senate when the Romans created democracy, it was completely rigged and corrupt, I wonder why the Roman Empire self destructed? History tends to repeat itself because these corrupt people think 3000 year old lies still work forever…..well, they dont and because they cant see past their own tiny dicks let alone the "vax" is an experimental unapproved gene therapy that does not have live-attenuated " covid " in it , so as such it does not conform to 70+ years of vaccine science, thus the term "anti-vaxxer" is not applicable.

Testing labs of all stripes also face worker shortages just like restaurants, said Mara Aspinall, a co-founder of Arizona State University’s biomedical diagnostics program who also writes a weekly newsletter monitoring national testing capacity and serves on the board of a rapid testing company.

For full coverage of the coronavirus pandemic

“The staffing shortage is very, very real and holding people back from increasing capacity,” she said.

Something as simple as proximity also still dictates how quickly test-takers get results.

“Northern Maine is a good example,” Aspinall said. “Anything you do with PCR is going to take an extra day, because it’s got to be flown or driven a ways.”

It's pretty inexcusable to have a turnaround time that long.

Even in a place like Longmont, Colorado, near many laboratories and hospitals, PCR samples from the local mass-testing site get shipped by air each evening to a lab in North Carolina.

FDA says Pfizer vaccine appears to work in young kids; study shows lower mortality rates for vaccinated people: Live COVID updates

  FDA says Pfizer vaccine appears to work in young kids; study shows lower mortality rates for vaccinated people: Live COVID updates Pfizer’s COVID vaccine appears highly effective at preventing symptomatic infections in young kids and caused no unexpected safety issues, feds say.The Food and Drug Administration posted its analysis of Pfizer’s data ahead of a public meeting next week to debate whether the shots are ready for the nation’s roughly 28 million children ages 5 to 11. The agency will ask a panel of outside vaccine experts to vote on that question and is expected to authorize the vaccine for young children as early as next week.

Most people who get Covid -19 will develop only the main symptoms - a cough or fever. But they could experience body aches, fatigue, sore throat and headache. The cough is initially dry, but some people will eventually start coughing up mucus containing dead lung cells killed by the virus. It will take time to recover from any spell in an intensive or critical care unit (ICU), no matter what the illness. Patients are moved to a regular ward before going home. Dr Alison Pittard, Dean of the Faculty of Intensive Care Medicine, says it can take 12 to 18 months to get back to normal after any spell in critical care.

How long does it take to get the results and how reliable is it ? The PCR-based viral test cost between 0 (someone else pays for you, usually the tax payer, sometimes your employer, sometimes a private entity) and hundreds of dollars (lots of profit for the physician and/or laboratory taking / processing the test ). However, depending on how the swab was taken , and in which phase of the infection, 20%–80% of infections are missed. This means that if the result is negative but clinical symtoms indicate Covid -19, a second test should be taken .

That mass-testing operation recently moved back to its original location at the county fairgrounds after a summer stint in a small church parking lot. Demand for PCR tests in the county quadrupled from 600 weekly tests in July to 2,500 in September. Chris Campbell, the emergency manager for Boulder County Public Health, attributes the heavy traffic to schools’ reopening, an increase in infections and the difficulty of acquiring over-the-counter rapid tests.

Campbell said it sometimes took residents four or five days to get their PCR results, although that has dropped to two as the contractor, Mako Medical, has built its laboratory capacity back up.

“It’s pretty inexcusable to have a turnaround time that long. It really does impact our ability to really stop transmission,” Campbell said. “And also, it has an economic impact to businesses, to schools, to early childhood facilities.”

Mako’s lab operates 24/7, and the company uses private planes to speed shipping, Chief Operating Officer Josh Arant said a statement. While Mako’s weekly median turnaround time never exceeded 72 hours last month, the statement said, in recent weeks it has returned results to area residents an average of 46 hours after specimen collection.

The Latest: Marchers in Rome protest work vaccine rule

  The Latest: Marchers in Rome protest work vaccine rule ROME — Thousands of demonstrators marched down Rome’s Via Veneto and other main streets on Saturday, some clashing with police, to protest a government rule requiring COVID-19 vaccines or negative tests to access workplaces next week. The certification in Italy, known as a “Green Pass,” takes effect on Friday and applies to public and private workplaces. To obtain one, people must either have had at least one COVID-19 vaccine dose, document recovery from the illness in the last six months or test negative in the previous 48 hours.

Portable devices can now eliminate the need to ship samples. They can do molecular analysis, including PCR analyses, in under an hour — a process that typically takes at least four to five hours in a lab. A Washington, D.C., testing truck has three Cepheid machines on board, each about the size of a printer. Combined, they can give a dozen people PCR results in under an hour, at no cost to test-takers.

Still, demand outweighs supply for such fast molecular tests, largely because of the roller coaster of case surges, said Doug Sharpe, the vice president of lab capital sales for Medline Industries, which supplies Covid testing components to labs across the country. “I don’t think anybody thought we’d be sitting here,” he said. “We’re selling more assays than we did at the height in 2020.”

Gigi Kwik Gronvall, an immunologist with the Johns Hopkins Center for Health Security who leads the center’s tracking of Covid testing, suggested that the variability in how long it takes to get results has created a seller’s market if companies can deliver results by a specific time. “People are going to pay for that sort of guarantee,” she said. “There’s this potential for people to get fleeced, for sure.”

MedRite offers PCR results analyzed in three hours in New York and Florida for those willing to pay more than $200 a pop. The company offers other tests, such as antigen tests and slower lab-based PCR tests, at no out-of-pocket cost.

Romania revives restrictions as hospitals struggle, jabs lag

  Romania revives restrictions as hospitals struggle, jabs lag BUCHAREST, Romania (AP) — Doctor Petruta Filip is working 100-hour weeks at a Bucharest hospital which, like hospitals throughout Romania, is struggling under an onslaught of COVID-19 patients in a country with worryingly low vaccination rates. The European Union country of around 19 million has only 35% of its adults fully inoculated against COVID-19 compared to an EU average of 74%, and is the second-least vaccinated nation in the 27-nation bloc in front of Bulgaria. That's crippling Romania's creaking health care system, which is also facing record-high death and infection numbers.

Celeste Di Iorio felt fleeced after she spent a day driving from pharmacy to pharmacy in Fort Collins, Colorado, in search of a test that would give an answer in less than three days. As a musician, she had been traveling out of state and wanted to know whether she might be infectious before she attended, among other things, a memorial for a relative who died of Covid. She and her partner eventually found rapid antigen tests at a pharmacy two cities over.

“We just paid $50 apiece for these tests, which pisses me off,” she said. “Because, you know, we’ve all been out of work for a year and a half, and this state has the money.”

Flu season could increase demand for Covid tests

In Helena, Montana, Stanfel has gotten a PCR test every week for many months because she takes immune-suppressing drugs for a rare condition called sarcoidosis. Her doctors told her to get the tests regularly because, even though she’s fully vaccinated — and has gotten an additional booster dose — she would most likely need a treatment of monoclonal antibodies as soon as possible if she contracted Covid to prevent an early infection from “developing into something really bad.”

When Stanfel found out that a friend she visited had later tested positive for Covid, she immediately got a test at her doctor’s office. It took five days to learn that she had tested negative.

Montana’s public health lab is in Stanfel’s city, but the volume of tests since early August has regularly exceeded the lab’s capacity, said Jon Ebelt, a spokesperson for the state health department. It has had to prioritize tests from hospitalized or symptomatic people and send other specimens to private labs, a process that can stretch the wait time for results to up to seven days.

In New York City, where mobile-testing vans are parked in every borough and in-person home testing is offered, residents report quick turnarounds for molecular tests because the labs analyzing their samples are close by.

For example, in Manhattan, Justin Peck got back from a road trip to Canada on a Tuesday night, walked about five minutes to a mobile-testing van Wednesday and had PCR results by Thursday morning, clearing him just in time to go to work for the first time in 18 months as a dancer in “The Phantom of the Opera” on Broadway.

Aspinall said flu season is likely to lead to an increase in demand for Covid testing as people with Covid-like symptoms seek answers about the causes of their illnesses, compounding staffing issues. “We’re at a very precarious point,” she said. “It’s not enough to go forward if the testing volume continues as I expect it will.”

Hungary offers to care for Romanian COVID-19 patients .
BUCHAREST, Romania (AP) — Hungary has offered neighboring Romania help in caring for coronavirus patients as the country faces an alarming surge of COVID-19 cases and a shortage of intensive care beds — pushing its health care system to the brink of collapse. Hungarian Foreign Minister Peter Szijjarto sent a letter over the weekend offering assistance to Romania in treating COVID-19 patients, Hungary’s Foreign Ministry told The Associated Press. “Negotiations are underway between the Romanian and Hungarian sides on the concrete form of the assistance,” the ministry said.
