模拟了来自小便池冲洗的载病毒颗粒运动。结果表明，与小便池引起的冲水相似，小便池冲水引起的颗粒物的轨迹表现为外扩散型。更令人震惊的是，与涡轮机诱导的颗粒的扩散性能（35秒内约0.93 m）相比，颗粒可以在5.5秒内达到0.84 m（人的大腿）。在这封信中，我们发现了一种更为猛烈的攀登趋势。公共卫生间应强制佩戴口罩，公共卫生间设施的防扩散改进迫在眉睫，特别是在当前的“SARS-CoV-2”危机中。
A virus-laden particle movement from urinal flushing is simulated. Similar to the toilet-induced flushing, results indicate that the trajectory of the particles triggered by the urinal flushing manifests an external spread type. Even more alarmingly, the particle can reach 0.84 m (man's thigh) in 5.5 s when compared with the diffusion performance of the toilet-induced one (around 0.93 m in 35 s). A more violent climbing tendency is discovered in this Letter. Wearing masks should be made mandatory in public washrooms, and anti-diffusion improvements of facilities in public washrooms are urgently needed, especially in the current "SARS-CoV-2" crisis.
