Hand, foot and mouth disease (HFMD) is a common infectious disease mainly caused by various enteroviruses, predominantly affecting infants and toddlers. Although adolescents and adults may not develop symptoms after infection, they can still spread the disease. This virus thrives and spreads in warm and humid environments. It is not sensitive to substances such as ether and dechlorinated bile salts; 75% alcohol and 5% lysol also cannot inactivate it. However, it is sensitive to ultraviolet light and dry conditions. Oxidizing agents such as potassium permanganate and bleaching powder, as well as formaldehyde and iodine tincture, can all inactivate the virus.
