UNITED STATES – Mucous membranes of the nose and mouth might play a “significant role” in curbing the spread of COVID-19, say scientists who call for more studies to evaluate the role played by this arm of the immune system in asymptomatic and mild states of the coronavirus infection. The analysis, published in the journal Frontiers in Immunology, noted that the mucosal immune system is the largest component of immunity, but hasn’t been a focus of much of the research on COVID-19 to date. “We think it is a serious omission to ignore the mucosal immune response to SARS-CoV-2, given its initial sites of infection,” said Michael W. Russell, a co-author from the University at Buffalo in the US.
