As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

As school districts across the country prepare to send kids back to school in-person, many bus drivers are voicing concerns about the potential for COVID-19 to spread on school buses, where oftentimes social distancing is nearly impossible.For the better part of 32 years, Cheryl Merritt has driven a school bus in Hanover, Massachusetts. She has driven in every kind of weather condition imaginable, but this is the first year she’ll be driving a bus during a pandemic.“I just want all the kids on the bus to stay safe and the drivers to stay safe. If we have a driver who gets sick, they’re going to be out for at least 14 days,” she lamented, as she turned her bus onto a side street in a residential New England town.Merritt’s concerns are shared by school bus drivers and districts across the country. Many school bus drivers have retired from other professions, meaning their age makes them more susceptible to catching the virus.“I don’t want this, I don’t. I’m not ready to die,” the 61-year-old Merritt said.School buses are presenting a particularly difficult challenge as districts try to send kids back to the classroom. When fully loaded with kids, most school buses fit about 77 students. Cramming students into a bus though would be a perfect place for COVID-19 to spread, so many states are advising bus companies to have only one student per bench. But taking some bus capacity down to about 12 kids means school districts would need to run double or triple the number of trips each day just to pick every child up.Transportation experts say adding more buses would be nearly impossible given a nationwide bus driver shortage, which existed long before the outbreak.“It doesn’t matter what you’re gonna do with kids once you get them to school, you have to get them there first,” explained David Strong, who works with the School Transportation Association of Massachusetts.Strong’s other concern is that kids won’t adhere to social distancing guidelines or mask-wearing requirements once they get onto a bus.“There’s almost no way to realistically social distance on a bus,” he added.To address concerns about the spread of COVID, many school districts are mandating that school buses keep their windows open year-round to help with the flow of air. Some districts are also adding bus monitors to ensure kids, especially elementary school students, are following new guidelines.As for Merritt, she sees herself and other bus drivers as the first line of defense when it comes to keeping COVID-19 out of the classroom.“When you stop to pick up a child look at them, make sure they don’t look sickly or they’re coughing,” she said. 2655

BAKERSFIELD, California — Several students from East Bakersfield High School were arrested on Thursday after two fights broke out on campus, according to the Kern High School District.The two fights were unrelated, according to KHSD spokesperson Lisa Krch. Seven students were arrested by KHSD Police.One fight was recorded and the behavior shown is "clearly unacceptable," Krch said.A graphic video has been circulating social media that appears to show a student being jumped and assaulted by a group of other students. The post claims the student suffered a broken neck and was hospitalized, but that has not been confirmed by KHSD. KHSD cannot confirm that video is one of the fights that happened Thursday.KHSD said the incident has been investigated and appropriate student discipline will be implemented. The district cannot comment on student discipline due to FERPA laws protecting the individual right of students, Krch said. 978

At 16 years old, Gabe Richards has been working hard to get good grades.He's secured straight As while being a part of the special education program at Marysville High School in Michigan.But, after getting invited to be honored at an academic awards ceremony Monday night, Gabe said he was disappointed to be told at the event that his invite was a mistake."We were really excited and don't get the chance to celebrate achievements all the time," said his mother Stefanie Grassel.Grassel said the faculty did apologize and acknowledge they mistakenly sent an invitation letter.However, as a mother, Grassel said she wants to see the policy changed to become more inclusive."It sends the message that they are less than a general education student, and that's wrong," she added.Richards also told us he feels disappointed after what happened. District superintendent Shawn Whiteman refused to do an interview in response to what happened. Instead, he issued the following statement addressing the matter:"The criteria for students to receive the distinguished “Academic Award” from Marysville High School are a GPA greater than or equal to 3.5 and that they are enrolled in a certain amount of academic-based classes.After speaking with our high school principal, it was evident that a mistake was made when identifying students for this award, due to the fact that a letter was sent home inviting a student to the ceremony who didn’t meet the full criteria.It is clear that the high school made an error in identifying students for this year’s award and we respectfully apologize for any grief this has caused.  Because of this, we will be taking corrective action so that this does not happen again in the future." 1768
