Toothbrush disinfection may help protect against COVID-19
It is established that COVID-19 can be transmitted, even from asymptomatic individuals, in different ways, including droplets, aerosols and fomites.
It is presumed that toothbrushes may act as reservoirs for microorganisms and favor the transmission of COVID-19 therefore disinfecting the brushes would be important to control the transmission of the virus in shared spaces.
In response to the article by Meister et al, "Virucidal efficacy ofdifferent oral rinses against SARS-CoV-2" (1), this letter aims to contextualize how rinses and/or their active ingredients could reduce the cross-transmission capacity of SARS-CoV-2 by toothbrushes in familiar (individual use) and collective (school and hospital) environments, emphasizing the importance of toothbrush disinfection in the transmission of SARS-CoV-2 and suggesting a hygiene protocol.MEISTER et al. found that several mouthwash formulations could reduce the viral load of SARS-CoV- 2 in saliva and its transmission.
