Healthy saliva prevents viruses from infecting cells.

Caption

SARS-CoV-2 is transmitted by the binding of the spike protein S1 on the viral envelope to the angiotensin-converting enzyme 2 (ACE2) receptor on the plasma membrane of human cells. Histone H2A and elastase protein found in saliva, bind to ACE2 receptors blocking SARS-CoV-2 from binding and infecting cells.
