According to a recent study, Covid-19 infects the cells in the mouth! It is well known that the upper airways and lungs are the primary sites of infection, but there are now clues that the virus can infect the cells in other parts of the body such as the digestive system, blood vessels, kidneys, and as previously stated, the mouth. This is the probable cause of the Covid-19 oral symptoms of the loss of taste, a dry mouth, and even blistering.
The study also points to the possibilty that the mouth plays a role in transmitting SARS-CoV-2, the virus that causes Covid-19, to the the lungs or digestive system via saliva laden virus from infected oral cells. A better understanding of the mouth's involvement could inform strategies to reduce viral transmission within and outside the body, researchers state.
Further research will be needed to confirm the initial findings as the "All Hands On Deck" approach continues to appear to be the best strategy to defeat the Covid-19 pandemic.
