represents the proposed role of probiotics in the management of COVID-19. Dysbiosis (an altered gut microbial flora) predisposes the individual to abnormal inflammatory status and increases the susceptibility to the disease. Probiotic supplementation helps to maintain symbiosis in the GIT and thereby modulate the immune system. The symbiotic state also helps to control the severity of the disease via the gut-lung and gut-brain axes.
