In the circle of friends, a screenshot of a "warm tip" spread among the circle group, saying that "many people who have regained their yang forget to change their toothbrushes after turning from yang to yin, and as a result, they themselves become infected again." Is that true?
In fact, this statement is wrong.
On December 19, Feng Cuiling, director of the Department of Traditional Chinese Medicine of Peking University People's Hospital, said that there was no need for special treatment of daily necessities after "Yangkang".
"The COVID-19 virus can only survive by relying on the human body. It will be inactivated soon after leaving the human body in the air circulation environment, so the used lipstick, cup, toothbrush, etc. do not need to be replaced", Feng Cuiling said, "From the original strain at the beginning of 2020 to the current strain of Omicron virus, although its transmissibility is getting stronger and stronger, the degree of disease caused by the virus is obviously lighter. The convalescent people have produced specific antibodies against the corresponding virus strain, so they need not worry about the virus remaining on the product".
How long can Omicron survive on our skin? How can we quickly inactivate the virus? Let's first look at the survival time of COVID-19 under various conditions, Neocoronavirus can survive for about 3 hours in the air. It can survive for 4 to 24 hours on the surface of paper articles. It can survive on plastic and stainless steel for 2 to 3 days. It can survive on glass for up to 9 days. That is to say, the smoother the surface of the object, the longer the survival time. The survival time of COVID-19 on human skin can be up to 21 hours, which is enough to infect family and friends around. So it is very important to wash hands frequently! Do you really want to change the toothbrush after the positive turns negative? How to kill? 50 ℃ hot water for 3 minutes, 90 ℃ hot water for 1 minute is enough to inactivate Omikjon. If we are really worried about toothbrushes, cups and other items, we can use hot water to iron them for a while. Clothes, quilts and sheets can be washed normally and then dried in the air. In addition, 75% alcohol, peracetic acid disinfectant and chlorine containing disinfectant, such as 84 disinfectant, can quickly kill the virus key, For door handle, we can choose 75% alcohol cotton pad to wipe the toilet. We can choose 84 disinfectant to wipe it, which can quickly inactivate the virus.
