There’s more strange news about the pandemic, for example scientists who track the coronavirus in our sewage, and computer models that show that flushing the toilet can launch persistent, pathogenic plumes into the room. And scientists have warned the WHO that infectious virus remains airborne. Also, how a shortage of glass vials could delay the deployment of a vaccine.
