Can the disinfection card be hung on your body to prevent novel coronavirus?

1. It is not recommended to use disinfection cards to prevent novel coronavirus.

2. The main component in the disinfection card is the chlorine dioxide generator. Chlorine dioxide is a substitute for chlorine-containing disinfectants, and its toxicity is much less than that of traditional chlorine-containing disinfectants. Novel coronavirus can be inactivated with chlorine-containing disinfectant, and chlorine dioxide can inactivate COVID-19 in composition.

3. However, it should be noted that the disinfection card is disinfected by generating chlorine dioxide gas. When chlorine dioxide is used as a gas, its own instability is high. Under normal pressure, the volume of chlorine dioxide gas exceeds 10 kPa (about 10% by volume), which is very dangerous.

Even if there is no explosion, inhaling chlorine dioxide may damage human respiratory mucosa or cause skin allergy. Therefore, it is not recommended to use disinfection cards to prevent COVID-19 infection.

The most effective measures to prevent COVID-19 are to wear masks, wash hands frequently, go out less and have more ventilation.
