mouth wash and covid 19
mouthwash for covid 19

Scientists from different parts of the world are working on possible vaccines against coronavirus, in addition to analyzing existing products to reduce the ration of infection from COVID-19, such as oral rinse and mouthwashes.

Many products play a great role in reducing infection rates, such as alcohol-based wipes and alcohol-based disinfectants. Scientists are now studying oral rinses and mouthwashes at Penn State College of Medicine in Hershey, PA.which was published in Medical News Today on November 6, 2020.

The Journal of Medical Virology recently published a study, according to researchers, found that many nasal and oral solutions can reduce the risk of transmission of the covid virus when infected people use them

. These
Professor of Microbiology and Immunology, Mr. Craig Meyers, said that we need methods to reduce the transmission of infections while we wait for the vaccine to be developed, these products are already available, tested, and are part of people’s daily lives.

Product Testing 

Meyers and his teammate used a virus called HCoV-229E that affects the human respiratory tract like the SARS-CoV-2 family of viruses, used different products against this virus in the laboratory, and found the reduction of viral activity with success. 

For nasal products, the team chose diluted Johnson’s Baby Shampoo as a nasal rinse, and CVS Health Peroxide Sore Mouth Cleanser as a mouth wash, Orajel Antiseptic Rinse of Chuch and Dwight Co.Inc. 1.5% Hydrogen Peroxide Solution of Cumberlan Swan Inc. Listerine Antiseptic by Johnson and Johnson Consumer Inc.Betadine 5% of Alcon Laboratories Inc.

Each of these solutions exposed to the human virus in three tests that lasted 30 seconds, one minute, and up to 2 minutes, all the selected products showed an impact on the virus of different levels, but no measurable effects.

The team had tested Johnson’s Baby Shampoo which killed 99% of the virus, while Crest Pro-Health killed more than 99.99% of viruses, the best product that has shown a good effect on the virus was Listerine Antiseptic which killed over 99.99% of viruses. in just two minutes, so Listerine and other mouthwashes can show excellent results.

Test results 

These results were similar to the report that was published in the Journal of Infectious Diseases, according to that study, routine oral mouthwashes reduce the viral load in the nose, throat, and mouth, and can help reduce the amount of viral transmission through sneezing. And cough 

The team found that these three products have one main ingredient, hydrogen peroxide, which affects the virus at a rate of 90% to 99%, supporting previous search results solutions containing hydrogen peroxide were effective. against SARS-CoV-2.

By using these products together, these products can help reduce the transmission of the COVID-19 viruses between an infected and uninfected person.

During home quarantine, the possible transmission of the COVID-19 viruses to other people living in the home can be reduced through the continued use of these products.


Use of these products with a combination of other prevention measures, the spread of covid 19 viruses can be controlled or reduced, As SARS-CoV-2 virus was not used in the study because it is much expensive and need level 3 laboratory conditions, All these tests were in a controlled environment which did not represent the true nature of the ecosystem  

More future trials are required with accurate tests that can create a suitable, affordable, and widely available prevention strategy, it is very important to know that even future research confirms the benefits of using these products, but they can never replace social distancing, facial covering, and others. Methods as an additional tool
