大量的细菌和病毒在家庭厕所中被证明在冲洗后仍然留在马桶中，即使连续冲洗也不能去除持久的部分。发现这是由于微生物吸附到碗的瓷表面，每次冲洗后逐渐洗脱。冲洗厕所产生的水滴被发现含有细菌和病毒，这些细菌和病毒已经被播种。冲洗后，细菌和病毒落在浴室表面上的检测表明，它们在空气中停留的时间足以在整个浴室的表面上定居。因此，存在人可能从马桶产生的气溶胶获得感染的可能性。
Large numbers of bacteria and viruses when seeded into household toilets were shown to remain in the bowl after flushing, and even continual flushing could not remove a persistent fraction. This was found to be due to the adsorption of the organisms to the porcelain surfaces of the bowl, with gradual elution occurring after each flush. Droplets produced by flushing toilets were found to harbor both bacteria and viruses which had been seeded. The detection of bacteria and viruses falling out onto surfaces in bathrooms after flushing indicated that they remain airborne long enough to settle on surface throughout the bathroom. Thus, there is a possibility that a person may acquire an infection from an aerosol produced by a toilet.
