mouthwash can't prevent epidemic.

novel coronavirus invaded the respiratory tract, so gargling can't clean the respiratory tract. Secondly, at present, there is no research result suggesting that mouthwash can kill novel coronavirus.

Japanese people rush to grab mouthwash. According to a report by Japan's Kyodo News Agency on the 5th, Governor Yoshimura of Osaka Prefecture of Japan publicly recommended mouthwash containing povidone iodine at a press conference on the 4th, saying that its ingredients can effectively prevent Covid-19. He said that medical institutions in Osaka have conducted experiments on 41 mild patients since June, and found that the Covid-19 positive rate in saliva dropped to 9.5% for patients who gargled four times a day with a mouthwash containing povidone iodine, while it was 41% for patients who didn't gargle. Therefore, we call on high-risk people with suspected symptoms, such as cold patients, restaurant employees and medical staff, to often use mouthwash to rinse their mouths. Yoshimura's public recommendation triggered Japanese people to snap up mouthwash, and mouthwash in many stores was? Sweep away? . Mouthwash can't kill the virus

First of all, the number of people who accept the experiment is too small, and the mouthwash experiment in Japan is not notarized. And using mouthwash, if povidone iodine remains in the mouth, it may reduce the sensitivity of PCR detection. Even if the virus in the throat is reduced, the virus in the lungs and nasal cavity is increased, which is meaningless for virus prevention. At present, no mouthwash has been developed to completely eliminate novel coronavirus. If you just want to block the passage of virus transmission, it is safer to wear a mask to travel.

The reason why the Japanese are rushing to grab mouthwash is not only because of the speech made by Yoshimura, but also because they are about to usher in the traditional Orchid Festival. In Japan, there is a tradition of returning home to worship ancestors, and the risk of infection will further increase under the large-scale personnel movement in summer. However, adhering to the concept of not believing in rumors and not spreading rumors, there is no need for everyone to buy mouthwash in the supermarket. First of all, not all mouthwash water is suitable for everyone. Secondly, if it is only to block the spread of the virus, masks are more suitable. Besides, the price of mouthwash is rising, but the price of mask is becoming more and more stable. Isn't it fragrant to choose a mask that is more convenient and safe?
