Social distancing (and tracing apps) won’t cut it. We know since start of April (via preprints) that transmissions occur at farther distance than 2 meters, by people simply TALKING (not sneezing nor coughing). Mists of infectious droplets stay in the air (and transported by HVAC airflows) for minutes! #FUCKINGMASKS4ALL For those arguing masks are impractical with facts like “N95 masks last only 4 hours” I’ll reply volcanologists and firefighters don’t wear the same protective equipment… Those N95 specs are for first line health care workers who literally swim in viral droplets pools. For mere mortals crossing in buildings, reused (homemade or bought) correctly worn masks will do the job of lowering Ro (below 1.0 hopefully).
