It’s time for the Super Awesome Science Show SASS Class on travel. I want to thank everyone who reached out to me. We received quite a few Emails and DMs about the episode although most of them centred on a few important questions. It shows that when it comes to travel, we all seem to have the same concerns and hopes for the future.  Our first guest is once again Ron St. John and he was the Director General of the Centre for Emergency Preparedness and Response at the Public Health Agency of Canada. He also helped develop the Global Public Health Intelligence Network which helps health professionals rapidly detect, identify, assess, prevent and mitigate threats to human health. He now works to help inform the public of threats associated with travel with his company, Sitata. Over the last few months, we have received a few questions regarding the use of ultraviolet light as a disinfectant. To help answer those questions, I’ve reached out to Rick Dayton. He’s been involved in preventing infections in hospitals for decades and has worked extensively with UV light. I’m sure you will find this discussion enlightening and dispel a few myths regarding this technique for keeping our surfaces safe.  If you didn’t hear your question, make sure to contact me on Twitter, by Email and now, via voice message at Speakpipe.com/SASS.
