Early in the pandemic, a loss of taste or smell was considered a hallmark symptom of COVID-19. Mouthwash may kill COVID-19 in the mouth temporarily, but the virus will make more copies of itself rapidly. In both cases, recruitment of inflammatory cells, cytokine release and generation of neurotoxic compounds may indirectly influence the neuronal signaling. To determine if virus in saliva is infectious, the researchers exposed saliva from eight people with asymptomatic COVID-19 to healthy cells grown in a dish.
