Co-principal investigator Duncan Hite, MD, said that as it becomes increasingly clear that vascular complications are common in COVID-19 patients, it’s important to pursue treatment options that target that aspect of the disease.
Vandy scientists: COVID antibodies don’t last long
The finding has implications for people, especially healthcare workers, who are exposed to the virus multiple times, and also for governments trying to assess overall infection levels. If antibody levels drop off quickly in asymptomatic people, researchers and governments may be dramatically underestimating the true population of people who’ve had the virus. The study also helps researchers determine the best possible window for recovered patients to donate COVID convalescent plasma.
In search of a more effective and affordable way to preempt the leaky masks, the pair collaborated with Lennon Rodgers, director of UW-Madison’s Grainger Engineering Design Innovation Lab, to come up with a way to tighten the fit of a standard surgical mask—something cheap and easy to produce “tons and tons” of. The result is the Badger Seal, a fitter composed of foam wire, clear tubing, and elastic cord. The filtration efficiency gains were dramatic. And the open source design can be created in around five minutes for less than a buck.
New app lets citizen scientists report mask-wearing data
MaskCount is a free web app available in 15 languages, and you can access it on various platforms, including Apple and Android. All you have to do is tap or swipe to count the number of mask/non-mask folks you see, and location data is sent to secure servers. To preserve anonymity, the app will prevent you from taking pictures or entering any identifying information about the people you’ve observed.
Contact tracing app helps PA citizens track COVID-19 exposure
Pennsylvania governor Tom Wolf and Secretary of Health Rachel Levine recently announced the rollout of a free app called COVID Alert PA.
Deemed “the official mobile app of the Pennsylvania department of health" the app developed by Irish software company NearForm. It can alert users if they’ve possibly been exposed to the coronavirus. Using Bluetooth tech, the app detects whether two users are within six feet of each other for at least 15 minutes. If a user tests positive for the virus, those who’ve had close proximity can get an alert.
The app runs on both iPhone and Android, doesn’t use GPS or location services, and keeps users’ personal information anonymous.
