Povidone-iodine is an antiseptic that is frequently used to clean skin prior to surgery. Current FDA regulations require that hospitals dispense povidone-iodine from single-use bottles, rather than large, multi-use containers, to prevent microbial contamination. This results in hospitals generating lots of product waste. However, if povidone-iodine vapor can kill microbes, then multi-use containers may be safe to use, since any bacteria that contaminated the inside of the container would soon die. The purpose of this research was to determine whether vapor from povidone-iodine could kill methicillin-resistant Staphylococcus aureus (MRSA), a common cause of hospital-associated infections.

In summary, this experiment demonstrated …
