Chief Cabinet Secretary Suga "Focus on research to verify the preventive effect of severe disease"

Regarding the fact that Osaka Prefecture announced the research results that gargling with a bactericidal mouthwash reduced the new coronavirus, Chief Cabinet Secretary Suga is conducting a study to verify the preventive effect of seriousness that will be done in the future I showed you the idea to keep an eye on.

Governor Yoshimura of Osaka Prefecture said that a new coronavirus decreased when a mild or asymptomatic patient under medical treatment at an accommodation facility gargled with a mouthwash containing povidone iodine, which has a bactericidal effect, on the 4th. Announced.

At the press conference on the morning of the 5th, Chief Cabinet Secretary Kan said, ``There will be an announcement that we will expand clinical research on accommodation and medical treatment facilities in the future, and carry out verification research on the preventive effects of aggravation, including efficacy and safety. I know that I was there."

On that basis, he also indicated that the government will also pay close attention to research to verify the preventive effects of the aggravation that will be carried out in the future.

Expert "There is also the possibility that the defense power will decline on the contrary"

According to Professor Emeritus Takashi Kawamura of Kyoto University who is familiar with the relationship between gargles and colds, it was asked whether mouthwashes with povidone iodine can prevent the disease from becoming severe. It is natural that mouthwashes reduce the virus in the mouth. As a result, it's not known at this point if the virus gargles into the cells as soon as it reaches the nose, throat, and lungs, while povidone-iodine Not only that, there is a possibility that the bacteria originally in the mouth will be eradicated and the defense power will be reduced," he said.

A group of emeritus professors Kawamura and his colleagues had previously conducted a study on the relationship between gargling and colds in about 390 people across the country, and as a result, people who gargled with water every day had more colds than those who did nothing. Is about 40% less.

On the other hand, those who were gargling with Povidone-iodine mouthwash did not reduce the number of people with colds.

In addition, Professor Emeritus Kawamura said, "If there is a virus in the mouth, there is a risk of infecting other people through the fly. From the viewpoint of preventing infection, However, I think that it is worth studying whether it is effective, but because the mechanism of virus infection is complicated and large-scale research is required to verify the effect, when using the results It requires careful judgment."

Ministry of Health, Labor and Welfare "It is not the stage recommended by the country"

A person in charge of the Ministry of Health, Labor and Welfare said at the meeting held by the opposition party in the Diet, "Generally, it is pointed out that gargling with an antiseptic has the effect of eliminating the virus, and it is effective in preventing infectious diseases as well as washing hands. I hope that the study will be expanded and more reliable evidence will be provided in the future, but I think it is premature that it will be effective at this point rather than at the stage of national recommendation. In order to recommend it, you have to provide some scientific basis.”

Out of mouthwash

There are a lot of out-of-stock mouthwashes at drug stores.

Among them, at the drugstore in Osaka city, there was a crowd at the sales floor immediately after the press conference on the 4th, and the prepared mouthwash was sold out immediately.

According to the person in charge of the store, customers inquired about the mouthwash's inventory and the arrival date of mouthwash until the closing time on the 4th.

In addition, on SNS, there were comments such as "When I went to the home center, the shelf of mouthwash was empty" and "I am in trouble because the mouthwash that I usually use is sold out".

Osaka Prefecture “Promote full-scale research”

Osaka Prefecture has announced that it will proceed with full-scale research, saying that gargling with a mouthwash that has a bactericidal effect may reduce the new coronavirus in saliva and make it difficult for people to pass.

Governor Yoshimura of Osaka Prefecture said in a press conference on the 4th, ``I will talk with a lie like a lie, but there is a research result that gargles with gargles may reduce the number of new coronavirus positives ".

According to the results, a mouthwash containing povidone-iodine, which has a bactericidal effect, was given 4 times a day to over 40 patients with mild or asymptomatic patients who were receiving medical treatment from June to last month. When I was gargled, the virus in saliva was less than in other patients.

Specifically, patients who gargled had a saliva PCR test positive rate of about 9% on the fourth day, while those who did not gargle had a 40% positive rate.

For this reason, Osaka Prefecture wants to carry out research on a scale of 1,000 patients with mild or asymptomatic patients and verify the effect of gargling.

Akifumi Matsuyama, Director of the Next Generation Drug Discovery Center at the Osaka Prefectural Hospital Organization Osaka Habiki Medical Center, said, "Reducing the saliva virus has the effect of reducing infections among people at home. I'm hoping that this is not the case with dozens or hundreds of cases, so I would like to confirm it in a large study."

On the other hand, Director Matsuyama told reporters, "In some cases, the amount of virus increases again in about an hour after gargling. It may hurt your throat if you gargling over and over again. So be careful."
