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.

小便池病毒传播

模拟来自小便冲洗的载有病毒的粒子运动。与马桶引起的冲水相似，结果表明小便器冲水触发的颗粒轨迹表现出外部扩散类型。更令人担忧的是，与马桶诱导的扩散性能（35 秒约 0.93 m）相比，该粒子可以在 5.5 秒内达到 0.84 m（男性大腿）。在这封信中发现了一种更猛烈的攀登趋势。公共洗手间应强制戴口罩，尤其是在当前的“SARS-CoV-2”危机中，迫切需要对公共洗手间设施进行防扩散改进。
