As cases surge, Covid-19 test results are taking longer to come back
With a higher demand nationwide for Covid-19 tests, Quest Diagnostics, one of the biggest commercial laboratories in the United States, says its turnaround time for results has increased.
The average turnaround time is now approximately two to three days for all patients and approximately two days for priority patients, Quest Diagnostics said in a press release Tuesday.
Last week, the company had said it was experiencing a "modest" increase, with the average test turnaround time at slightly more than two days. It warned that as the number of cases nationwide continued to grow, so would the demand for tests, and testing capacity would be further stretched.
The delays come as many people are seeking Covid-19 tests ahead of Thanksgiving.
TikToker goes viral for sharing AstraZeneca vaccine trial experience
Last week, Ashley Locke, a Tennessee-based TikTok user, posted a video of herself participating in the AstraZeneca Covid-19 vaccine trial.
Since then, the video has racked up more than 2.6 million views.
“The attention that it’s got ended up just being completely mind blowing to me," Locke told NBC News affiliate News 4 Nashville.
In the clip, Locke shows herself arriving at the facility, meeting with a doctor and, toward the end of the clip, herself receiving an injection of what she explains is either the vaccine or a placebo.
"Now I have check-ins and get blood drawn for the next two years to see how everything is going," Locke writes in the video.
In subsequent videos posted to her account, Locke answers viewers' questions about the vaccine trial and describes her check-ins with the trial's doctors.
The videos have not only given people a window into what it's like to be a part of a Covid-19 vaccine trial — they've also encouraged others to join.
Clinical Research Associates, the Nashville office where Locke is participating in the trial, told News 4 Nashville that they've had an influx of sign ups since Locke's video. They said those signing up say they heard about the trial through social media, with some specifically citing TikTok.
"To think that I had a hand in sharing that information and getting more people involved in the trial, that just feels really cool. I mean I definitely didn’t expect that so that’s awesome,” Locke told News 4 Nashville.
6 dead, more than 70 infected in Massachusetts nursing home
Six residents at an assisted living facility in Massachusetts died after testing positive for the coronavirus, officials told NBC Boston on Monday.
The coronavirus outbreak has infected more than 70 residents and employees at Atria Marland Place in Andover, Massachusetts, said Kymberly Codair, regional vice president of Atria Senior Living.
"Our thoughts are with their families during this difficult time," Codair said in a statement to NBC Boston.
Codair added that all residents who tested positive are under quarantine and receiving medical care, and the facility is operating with "escalated safety protocols," including restricted access to visitors, regular temperature checks, symptom screenings, and proper PPE for employees.
New York City emergency room doctor warns of potentially deadly consequences of Thanksgiving travel
A New York City emergency room doctor is warning Twitter users of the possible deadly consequences of travel and family gatherings during the holiday season.
“There’s just no foolproof way to make holiday family meetups zero-risk,” tweeted Craig Spencer, 39, a doctor of emergency medicine at Columbia University Hospital.
“In a couple of weeks, we're going to hear a lot of stories of people who got together from all over the country, interacted with their family members, and those family members are sick or maybe even died,” Spencer told NBC News over the phone.
While doctors rely on personal protective equipment and will know which of their patients are Covid-19 positive, people attending meet-ups won’t have those same precautions, meaning the risk is going to be very high for many across the country, he added.
Spencer hopes he and his fellow emergency room staff will have time to gather for some food on Thanksgiving, but isn’t holding his breath. “2020 is different than every year before,” he said.

The deal with Moderna is the sixth secured by the E.U. Commission with pharmaceutical companies, allowing its 27 member countries to buy more than 1 billion doses once the shots are ready.
