Preventing Norovirus outbreaks is complicated by the fact that the virus is highly resistant to several different chemical disinfectants.
Bleach, a chlorine-based solution, is currently the most effective treatment, but researchers are seeking more convenient alternatives.
One such alternative is cold plasma, also known as non-thermal plasma. This “fourth state of matter” consists of ionized gas molecules at room temperature. These ions can destroy many kinds of microbes, but their effect on viruses was less clear.
