A: In the community setting, someone who meets the criteria for being a close contact to a case of COVID-19, meets the criteria REGARDLESS of whether or not they or the case had on a mask. Why is someone considered a close contact regardless of whether they had on a mask? While cloth masks are …
A: Nope to those three, but yes to leadership, preparation, testing & tracing, and calm, science-based communication. It’s true: Maine is doing very well by almost all metrics used to track the epidemic. While 21 states had their highest daily case counts in the last 3 weeks, Maine’s single day record cases happened way back …
Q: Jennifer from Texas asks: Are there really false-positives from COVID tests? If so, how is it possible for a test to pick up something that is not there? A: Yep, they exist. High-profile false-positive COVID tests are making the news again after Michael Burton of the New Orleans Saints erroneously tested positive the day …
A: Testing individuals for COVID-19, while a necessary component of our public health strategy, doesn’t 100% prevent those who are infected with SARS-CoV-2 from transmitting the infection to others BEFORE they test positive. The type of testing strategy used by the White House was to screen individuals for COVID-19 using a rapid antigen-based test (i.e., …
A: A negative test result does NOT mean that Mr. Pence and Mr. Biden are COVID-free… even if that happens to be really inconvenient for them. Everyone who has been near the President of the United States in the last week (or who has been around anyone else with COVID-19 for that matter) should self-quarantine …
A. The Helsinki-Vantaa airport welcomed COVID-19-sniffing dogs to their staff last week, hoping to use their keen sense of smell to detect COVID-19 positive patients up to 5 days before symptoms appear. Dubai International Airport also has a team of dogs sniffing for COVID-19. Here’s how the airport testing works: Prospective passengers rub a wipe …
From our follower Question Box!! A: Yes, while we know that children are less likely to experience severe illness due to COVID-19, increasing evidence tells us that children can spread (transmit) the virus. But, it is not clear if they are more likely to do so than adults or if likelihood of transmission varies by …
A: Yes! To help, we have two excellent posts written by our colleague, Your Local Epidemiologist (YLE). Post 1: PCR vs. Rapid antigen test: PCR (rapid or not) outperforms the antigen test. Still, there is promise in the new tests being developed and YLE goes through the numbers here. Post 2: The CDC’s new testing …
Andrew Joseph, Helen Branswell, and Elizabeth Conney of StatNews have pulled together a tour-de-force synthesis of what science does – and does not – yet know about SARS-CoV-2 and its companion disease, COVID-19. A truly terrific read Some highlights: SPACE AND PLACE MATTER. A LOT. Transmission risk is greatly elevated in crowded indoor spaces with …
A: It’s called SalivaDirect, and it was developed by researchers at the Yale School of Public Health with funding from the NBA. And it’s good news! On Saturday, the FDA granted an Emergency Use Authorization (EUA) for the new test, which has some distinct advantages over the more common PCR (polymerase chain reaction) tests currently …
