Informing health decisions and actions
Description
Background There has been increasing use of body worn labels or tags, impregnated with chemical disinfectants, and worn on a lanyard or clipped to clothing, with the purpose of protecting against SARS-COV-2 virus. These are marketed as air purifier capable of removing viruses, bacteria and smog and creating a ring of purified air around the wearer that will protect the wearer from respiratory pathogens such as SARS-COV-2 virus. The proposed mode of action is that these cards release disinfectant into the air constantly over a long period, for around one month. There is no available evidence that these cards provide any protection against COVID-19.
