@Comparativist It is, but there is still a risk of infection, particularly at close range, which is documented both in theory and by case reports. 2% per hour (or perhaps 6% with much more infectious variants) may seem low, but it adds up.
@是的，但仍然存在感染风险，尤其是近距离感染，这在理论和病例报告中都有记录。每小时2%（或者可能是6%，感染性更强的变种）可能看起来很低，但总的来说是这样。
