A novel coronavirus has emerged in late 2019 capable of causing a severe respiratory disease known as COVID-19. Its pathogenesis appears to be the initiation of an immune response and resulting cytokine storm that damages the healthy lung tissue of the host. Some epidemiological studies found bacillus Calmette-Guérin (BCG) vaccine can help to decrease morbidity and mortality of the viral infection. We aim to review and summarize what is known about COVID-19 and the current implications of
intravesical BCG with regard to the disease.
