Answer

An in vitro study using adenovirus 8 and A549 human epithelial cell cultures demonstrated that povidone-iodine at a concentration of 1:10 (0.8%) is highly effective against free adenovirus, less effective against intracellular adenoviral particles in already infected cells, and not significantly cytotoxic for healthy cells. Thus, povidone-iodine 0.8% may represent a potential option to reduce contagiousness in cases of adenoviral infections. [11]
