Oral Dis. 2021 Apr;27 Suppl 3:707-709. doi: 10.1111/odi.13368. Epub 2020 May 11.


We report two cases of COVID-19 showing negative respiratory swabs but positive salivary samples at the same time. These findings rise the concern about how to manage these patients before hospital discharging, thus avoiding contagion among their family members or a second coronavirus wave once the lockdown is over.
