The novel Coronavirus Infects Cells in the Mouth – Saliva May Play Role in COVID19 transmission

An international team of scientists has found evidence that #SARSCoV2, the #coronavirus that causes #COVID19, infects cells in the mouth. While it’s well known that the upper airways and lungs are primary sites of SARS-CoV-2 infection, there are clues the virus can infect cells in other parts of the body, such as the digestive system, blood vessels, kidneys and, as this new study shows, the mouth.

The potential of the virus to infect multiple areas of the body might help explain the wide-ranging symptoms experienced by COVID-19 patients, including oral symptoms such as taste loss, dry mouth, and blistering. Moreover, the findings point to the possibility that the mouth plays a role in transmitting SARS-CoV-2 to the lungs or digestive system via saliva laden with virus from infected oral cells.
