Lots of scope for variation here, at the national level all the way down to the individual neighborhood and even dwelling. That, I think, should be the takeaway, oft-misconceived, from the concept of “airborne”: Not that Covid is insanely infectious, but that it’s capricious. If the wearables crowd would stop focusing on magic glasses that augment reality with advertising, and help us visualize air currents instead, they would be doing a lot to help. Prove me wrong, techies!
Antibody Responses to SARS-CoV-2: Let’s Stick to Known Knowns (PDF) Journal of Immunology. From the Abstract: “In this article, which is part opinion piece and part review, we argue that the normal cadence by which we discuss science with our colleagues failed to properly convey likelihoods of the immune response to SARSCoV-2 to the public and the media. As a result, biologically implausible outcomes were given equal weight as the principles set by decades of viral immunology. Unsurprisingly, questionable results and alarmist news media articles have filled the void. We suggest an emphasis on setting expectations based on prior findings while avoiding the overused approach of assuming nothing. After reviewing Ab-mediated immunity after coronavirus and other acute viral infections, we posit that, with few exceptions, the development of protective humoral immunity of more than a year is the norm. Immunity to SARS-CoV-2 is likely to follow the same pattern.”
On my recent trip to India (Trichy & Karaikudi in Tamil Nadu), I was *fascinated* by the trucks, lorries and buses on the roads. Going through my notes, I find myself wanting to look them up. The brand that stood out the most for me was Ashok Leyland: https://t.co/FoP4hvZkmLpic.twitter.com/5sXM09aiPb
