SARS-CoV-2: What Can Saliva Tell Us?

Saliva can be relevant also for the fact that in these samples can be investigated the virus in active replicative status, that likely is the transmissible form. Additionally, to date, from the beginning of the pandemic of COVID-19, the rate of viral infected symptomatic peoples globally had an exponential increment during the recent weeks. However, the role of viral molecular feature and the potential genetic changes involved in this high transmission are not well investigated yet. Thus, enrolled saliva samples from different patient at different times can be relevant to investigate molecular genetic changes of transmissible viral form that can be of interest for vaccine and therapeutic antiviral development.
