Transcript for School buses adapt to keep kids safe during COVID-19 crisis
and no mask wearing has drawn the the. Reporter: This morning school is back in some parts raising questions how to safely transport kids to class. Social distancing and masks aren't just for the classroom. Every student that rides the bus must wear a mask. Reporter: For many students, this new routine will start on the bus. And load the bus from the back to the front. Reporter: This video from Casey county schools in Kentucky shows what that might look like. Parents asked to check their kids' temperatures before they board and children asked to use hand sanitizer as they head to their seats. Once they leave, a team fully disinfects the bus. They say the risk is low if the right precautions are taken and ventilation is key. The main problem with a bus is that you don't have a lot of circulation. There is nothing that happens naturally unless are you in a position where you can open the windows. Reporter: The CDC recommends students wear face coverings and sit one child Perot, skipping rows when possible. To achieve that, the national association for but pill transportation says there should be fewer kids on board. One of the largest things that's being done is the changing of times, to enable school buses to run multiple routes per day to get students to and from school safely. Reporter: Some parents are avoiding the bus altogether. That's not an option with some parents. If they have the ability to transfer their students to school, we'd ask them to do so. Reporter: Another walking school buses, a pre-pandemic that could be help if Kentucky. They say this could allow groups of kid who live nearby to get to school safely led by an adult chaperone picking up other children along the way. One primary concern for a lot of school districts is that if they cut back on transportation options, it would disproportionately impact communities with fewer resources, the same communities hit the hardestpy the pandemic. It's so complicated. Let's get more answers from Dr. Jen Ashton. We see all the problems there with taking buses. Some of the cautions school districts are taking. What else can parents do to keep their students safe? I think, first, we have to understand, George, there is no such risk as dropping the setting to zero. Not just in the pandemic, but if life. It's lower the risk as much as possible. I think parents need to be and should be creative. They should be flexible and above all, we need to put those students' safety first, including the people around them. So I think the name of the game this academic year is to explore your options and for parents as well as schools have a plan B, have a plan C and if necessary even have a plan D. So if parents have the choice, would you recommend keeping their kids off the bus? Well, I think we have to distinguish between being idealistic and being realistic. That's not the reality for a lot of parents and as we heard in the piece, it's really about ventilation and distance. So there are viral factors. There are human factors. We can't control how this virus behaves, but we can make modifications and control how we behave and we heard great examples of that in the piece. I think it's not a one size fits all approach. It will have to depend on what's going on in that area, what's going on in that region. What kind of transmission we're seeing and the individual health and risk factors of those students and the people at those students' homes. There are a lot of factors in play. Right now, a lot of questions. We have to remember we have never been in this situation before. So much for parents to consider. Thanks, very much. You will be back in our next hour with the CDC's new warning about a potentially deadly illness that strikes children.
