June 26th: Evaluation of hospital-grade disinfectants on viral deposition on surfaces after toilet flushing

The purpose of this study was to quantify the effect of virus contamination on the washroom surface after rinsing and the disinfectant added to the toilet before rinsing to reduce surface contamination. Prior to rinsing, pollution of the washroom surface was assessed with or without addition of E. coli MS 2 to the toilet. Then test the bathroom and the bowl of water with various surfaces for the presence of the virus

The results showed that the flushing of the toilet bowl causes extensive contamination of the washroom surface (the edge of the toilet bowl, the top of the toilet seat and the lower part of the toilet seat). When disinfectant is added to the toilet before rinsing and the contact time is over 15 minutes, the level of contamination of the toilet and surface after rinsing will decrease. Hydrogen peroxide produces negligible virus (<1 log 10) in the toilet. Peracetic acid and quaternary ammonium salts have the most reduced log of viruses in toilet organic matter.

Thomas Crapper did not invent the flush toilet; in the 26th century BC, the Indus Valley civilization used the flush toilet for the first time. The pioneer of the modern toilet was invented by Sir John Harrington, the Elizabethan court servant, and his book on his subject matter was expelled from the courtroom when attention was drawn from the important person. However, Crapper has done a lot of work to increase the visibility, and some Crappers, including the "no valuable wastewater blowing prevention device" which makes it possible to efficiently clean the toilet without using washing water for a long time It brought about innovation. The word nonsense is not his name (see words, phrases, and languages ​​above)

The purpose of this study was to quantify the effect of virus contamination on the washroom surface after rinsing and the disinfectant added to the toilet before rinsing to reduce surface contamination. Prior to rinsing, pollution of the washroom surface was assessed with or without addition of E. coli MS 2 to the toilet. Next, I tested various surfaces of the bowl water and toilet for the presence of virus. The results showed that the flushing of the toilet bowl causes extensive contamination of the washroom surface (the edge of the toilet bowl, the top of the toilet seat and the lower part of the toilet seat). When disinfectant is added to the toilet before rinsing and the contact time is over 15 minutes, the level of contamination of the toilet and surface after rinsing will decrease. Hydrogen peroxide produces very few viruses in the toilet (<1 log 10)

June 26: Evaluation of the effect of hospital disinfectant on virus adhesion to the surface after washing toilet

In all the tests, the end of the toilet bowl, the top of the toilet seat and the bottom of the toilet seat were contaminated and no disinfectant was added to the bowl before rinsing. When the contact time is over 15 minutes, all disinfectants significantly reduce the surface concentration. Hydrogen peroxide reduces the virus slightly in the toilet (<1 log 10). Peracetic acid and quaternary ammonium salts reduce the logarithm of virus in toilet organic matter
