The disinfection tunnels or booths that have become popular at the entrance of some office buildings and hospitals would be more harmful than beneficial, according to Colombian health authorities, cited by El Tiempo.
One of the main reasons for harm put forward by the investigation of the capital newspaper is that the disinfectants used are effective for cleaning surfaces, but that the manufacturers of these devices have not carried out sufficient studies to determine how harmful they are if they are applied directly to the skin. .
For the Ministry of Health, explains El Tiempo, the use of substances such as ozone, hypochlorite, ethanol, glycolic acid, peroxide of hydrogens and others could damage the skin or mucosa.
The report warns that when they enter, many people do not do so with masks and often in shirt sleeves, which further exposes the skin to these substances.
And for those who wear a mask, the particles of these aerosols adhere to the mask and are prone to being breathed by the person, with the health risks that this entails: “Hydrogen peroxide, sodium hypochlorite and quaternary ammonium in contact with human beings they can generate eye, nasal, dermal and respiratory irritation ”, reads the newspaper’s note.
The spraying of disinfecting substances on the person is also not sufficient to eliminate virus particles that may be attached to clothing or shoes and do generate a sense of false protection that could lower your guard Faced with more effective measures to keep contagion at bay, the note says.
Finally, El Tiempo concludes that the use of these disinfection devices has been discontinued in countries such as Peru, India and Indonesia, where they have become aware of their unwanted side effects and are only recommended for health personnel who enter them with the suitable suits and with the mucous membranes (eyes, nose, mouth) properly protected.
