Top health officials are considering “pooled testing” as a way to ramp up COVID-19 tests.Here's how it works:Instead of testing each sample individually, labs pool together a certain amount, like 10, in one tube with one test.If it's negative, you double check it, and then you're done.If there's a positive, you break it down either into smaller pools or individually for further testing.“So, there are advantages, mostly cost savings, that's the huge advantage of pooling, also the ability to go through a very large volume of specimens,” said Dr. Thomas Quinn, an infectious disease researcher at National Institute of Allergy and Infectious DiseasesQuinn worked in one of many labs that used the pooling technique during the HIV epidemic in the 1980s. He says the difference between then and now is the tests themselves.Pooling dilutes the samples. The HIV tests were very accurate, so that wasn't an issue, but with COVID-19, the tests aren't as reliable.The other problem is pooling takes more time in the lab, even with robotic equipment helping.“We need to get everyone tested and everyone wants to know what's the result of my test within 24 hours. That's very hard to do with pooling,” said Quinn.Quinn isn't recommending pooling for individual testing right now. He says it could be more useful in big surveys, when it's not an emergency. 1357

There's a new way to do contact tracing in the works and it could make a difference for health care providers during flu season.Vibrent Health just got a contract with major health institutions to develop the platform.Part of the idea is for users to enter their symptoms and find out if they're more likely to have the flu or COVID-19.“Health care facilities do get bombarded with perhaps people thinking that they have COVID when they just had flu, so the idea is how do you help the health care organizations to reduce some of the burden,” said Praduman Jain, founder and CEO of Vibrent Health.The technology is designed to be embedded in other apps that organizations and intuitions already use, like a university application for students.“So, make it easy for people and don't try to change their behavior,” said Jain. “They are already using certain applications that this can become a part of.”The app uses Wi-Fi networks to find out if you may have been close to someone with the virus.It could help cut some contact tracing work for public health departments. Instead of calling everyone that may have come in contact with the virus, the app can report that information.“There are only so many people, so many human beings, so many people that public health departments can hire to do that contact tracing, so technology becomes really important,” said Jain.Development is still in its early stages. Right now, the focus is on fine-tuning the algorithms to evolve along with changing data on the coronavirus.Broader testing is expected in the first few months of 2021. 1585

This afternoon around 3 pm, what police say appears to be a stray bullet came through one of our preschool classrooms. Thankfully, no children, teachers, or staff were injured.Our teachers immediately took the children to the chapel, locked down the campus, and called police. Officers arrived shortly after the incident and are now conducting their investigation. At this point, we don't have any information from the police on where the bullet came from but they do assure us that there is no ongoing risk. Given that the bullet fell just inside the window, it appears to have been fired at a great distance, and not be a targeted shooting, according to the police.All of our parents have been notified and are coming to pick up their children now. The school will be closed tomorrow. Out of an abundance of caution, the St. Petersburg Police will be providing additional patrol and security.We are extremely grateful that no one was injured and appreciate the fast action of our teachers, staff and the St. Pete Police to keep everyone safe. 1052
