  1. Dear Dr Campbell, Thank you for your hands-on approach in dealing with the statistics about the Covid-19 pandemic. What listening to you and watching your videocasts has done for me is to be more aware getting infected. I live in Europe and tonight I was invited to a Tango party with a friend of mine as the star of the band and I really, really want to go. But I cancelled. Why? Because of your very practical advice and because everytime it seems I read in the paper when a group of people get together to have a couple of drinks, they come down with the virus a few days later. It's hard to stay home week after week, but again, thanks to you we're in good health in this house, and if what you say is true about a second wave on the horizon it's the best advice one can take and stay out of danger at home until the pandemic has died out. Earlier, I wrote about air purification technology, and what I had envisioned has already been invented. James M. Tour Ph.D. told me the technology is available to clean the air of bacteria and virus. HEPA filters in HVAC systems can do this, but they are expensive. But they are used every day in clean rooms and hospitals. Rice University in Houston, Texas has just installed UV-C HVAC filters in every building on campus which kill bacteria and deactivate virus capsids. There are plasma filters and others, so now the question is: Are we going to go this way from now on? Isn't the lesson of the 2020 pandemic that we need to scrub the air we breathe indoors?
