Common Mouthwashes Could Reduce COVID-19 Viral Load in the Mouth

  • Researchers have found that some common mouthwashes may have the potential to reduce the viral load of COVID-19 in the mouth among those infected with the disease
  • Researchers at Penn State College of Medicine made this finding in a study that showed that some oral antiseptics, mouthwashes, and a baby shampoo could inactivate human coronaviruses
  • However, some researchers are skeptical about this finding, stating that the study did not specifically test the SARS-CoV-2 virus
  • An earlier study, published in July in the Journal of Infectious Diseases, made a similar finding that linked certain oral rinses to reduced oral COVID-19 viral load
  • In the study, German researchers tested eight commercial mouthwashes in a cell culture test and found the SARS-CoV-2 virus was reduced dramatically after 30 seconds
  • Although the researchers say more studies are needed to consolidate the findings, they suggest that using oral rinses could be an extra help in curbing the spread of the virus
