Two cases of COVID-19 with positive salivary and negative pharyngeal or respiratory swabs at hospital discharge: A rising concern

Lorenzo Azzi et al. Oral Dis. 2021 Apr.

Abstract

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.

Keywords: COVID-19; Coronavirus; SARS-CoV-2; nCoV-2019; saliva.

The temporal line of the clinical course in the two patients shows how their salivary samples tested positive, while the pharyngeal or bronchoalveolar swabs were negative on the same day (Patient 1 on March 19) or during the interval between two consecutive salivary swabs (Patient 2, March 23–28)
