我们公布了“新型冠状病毒飞沫感染的新模拟结果”。
我们第一次验证了具有高度传染性的 Omicron 菌株。
仿真结果：
即使感染者戴着口罩
在 50 厘米的距离内
事实证明，感染的风险会急剧增加。

对于 Omicron 和 Delta 菌株，
他指出，有必要回顾一下目前为止2m的社交距离。
小气溶胶对无纺布的阻隔作用有限。
戴口罩也不用担心
拉开距离，缩短接触时间等。
采取措施很重要。

Computer simulation: Omicron infection risk rises within 50 cm even with masks
A simulation using a supercomputer
shows the risk of infection with the Omicron coronavirus variant increases when people talk to each other within a distance of 50 centimeters even when they are wearing masks.
A team of researchers from the RIKEN research institute and others
conducted the simulation on the spread of coronavirus droplets using the Fugaku computer.
The simulation was based
on past cases of cluster infections on the assumption that the Omicron variant is 50 percent more infectious than the Delta variant.
The results show that
the average rate of infection during a 15-minute conversation with a person infected with the Omicron variant who was wearing a mask was almost nil when other people are one meter or more apart.
But the rate increased to around 14 percent
when they are within 50 centimeters from each other.
The researchers warn people should keep a sufficient distance from each other even when they are wearing masks.
