In a recent study published in the Journal of Medical Virology, researchers at Penn State College of Medicine stated that some oral antiseptics, mouthwash and a baby shampoo “may have the ability to inactivate human coronaviruses” while talking, sneezing or coughing. Although further testing is needed.
“Researchers found that many nasal and oral rinses had a strong ability to neutralize human coronaviruses, suggesting that these products may have the potential to reduce the amount of virus spread by those who use COVID-19- Are positive, ”Penn State said in a release.
The study has not specifically tested the SARS-CoV-2 strain of coronovirus, although the findings suggest researchers believe that some oral rinses and other tested products could potentially reduce the spread of SARS-CoV-2 Can help, the report said..
Craig Meyers, a professor of microbiology and immunology and obstetrics and gynecology who led the study, along with his team of researchers, is studying various methods to reduce the transmission and spread of human coronaviruses with aerosolized respiratory droplets , Which is one way to broadcast SARS-CoV-2.
According to Meyers, “I was in the drugstore and I just saw a bottle of Listerine, and said ‘kill germs that cause bad breath.” And I thought, ‘What the heck?’ I bought it and we threw it into the study and we were a little surprised at how well it worked at neutralizing human coronavir, Meyers told CNBC Make It.
Another study published in July by the Journal of Infectious Diseases added some oral reins to inactivate SARS-CoV-2. Researchers in Germany tested eight commercial mouthwashes in a cell culture test and found that the Sir-COV-2 viral load was dramatically reduced after 30 seconds. However, the authors concluded that further studies are still needed and that mouthwashes are not suitable for the treatment of Kovid-19.
Meyers also states that if they test the tested products (J & J Baby Shampoo, Orajel Antiseptic Rinse, Listerine Antiseptic and Peroxide Sore Mouth), more clinical trials are needed to determine if The amount of virus in the Kovid-19 positive can be reduced. Oral cavities of patients. More testing is also needed to determine which specific elements are in the virus neutralizing solutions. However, Meyers says the findings so far are “promising”.
“Even though the use of these solutions can reduce transmission by up to 50%, it will have a major impact,” Meyers said in a release on Monday.
To conduct the study, Meyers and his team of scientists used a strain of human coronavirus called 229e, which is structurally similar to SARS-CoV-2. They put the virus in a solution with each product for 30 seconds, then for one minute and finally for two minutes. Then, to find out how inactive the virus was, the researchers diluted the solutions and placed them in contact with human cells.
Meyers states that they have used 229e instead of SARS-CoV-2, as special features are required to use SARS-CoV-2 and most of them have been booked during the pandemic. Plus, viruses such as 229e have a strong basis for being an accurate surrogate for “SARS-COV-2”.
After a few days, they counted how many human cells survived after exposure to the products. Among the findings, the 1% baby shampoo solution inactivated the virus by 99.9% after two minutes, while many mouthwashes were able to inactivate the virus by 99.9% after only 30 seconds of contact time.
Without more clinical trials, Meyers says it is too early to know how these findings will be put into use by people to possibly slow the spread of Kovid-19.
Although Meyers uses mouthwash twice a day in person, they do not state that people use these products to fight Kovid-19.
“I’d say you wear your mask, make up your social mess. Guess what you’re doing, but it might just be an extra help,” Meyers says.
