Of Tokyo's record 78 infections today, 49 were not traceable and the spokesperson for the crack Infection Tracing Squad stated that a number of infectees were not cooperative in identifying the source of their infection. Make of that what you will.
Speaking entirely for myself, I've hung up my mongering coat for the duration. I had viral pneumonia as a child, and have no desire to repeat the experience, especially while thousands of other people are hogging the ventilators. Moreover it's not just about me but about the people I could potentially pass it on to, potentially without realizing.
