Virus transmission from urinals
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....

Summary: | 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. |
