For example, singing, coughing, and sneezing generate warm, moist, high-momentum gas clouds filled with droplets that move faster than typical ventilation flows, the researchers wrote. Studies suggest these droplets can travel up to eight meters (about 26 feet) "within a few seconds." ...snip... "Further work is needed to develop specific solutions" for various indoor environments, the researchers concluded. "Physical distancing should be seen as only one part of a wider public health approach."
