These arches or tunnels sanitizers have been installed in clinics and hospitals of various states of the country such as Zacatecas, Baja California and Coahuila.
The ministry of Health warned against the use of arches and tunnels sanitizers, to determine which, until now, there is no evidence that they are effective for performing a disinfection of the Covid-19 and, on the contrary, may increase the risk of dispersion.
In recent days these arches or tunnels sanitizers have been installed in clinics and hospitals of various states of the country such as Zacatecas, Baja California and Coahuila.
In a press conference night from the National Palace, Hugo López-Gatell Ramirez, deputy secretary of Prevention and Promotion of Health, warned about this risk
spread of the coronavirus not used correctly.
“We assume that there is a person who has Covid and their airways get rid of the virus. What is going to happen is that as you breathe in, these virus particles will be mobilized and if the time of sanitation is not the technically recommended and that depends on the volume of the person, the area to be covered, and also of the power of the substances sanitizers. It may be that the person spends very little time and that is not sufficient to inactivate the virus, and we have the opposite effect: the risk of spread“ explained the federal official.
López-Gatell added that if such tunnels satinizantes were not a risk “we would not have said anything, only would have said you’re wasting money. But they do have a risk,” he said.
This week we installed a tunnel in the Unit of Family Medicine number 23 of the Instituto Mexicano del Seguro Social (IMSS) in the municipality of Sabinas, Coahuila, reported local media. Another plus was placed last week at the entrance of the clinic 57 of the IMSS in the municipality of Zacatecas.
In the border town of Mexicali, Baja California, installed an arc sanitizer, which sprays chemical to the people who cross the international port, walking from the united States. They also installed another at the entrance to the General Hospital; one more in the airport, and a fourth tunnel in the Municipal Palace.
The mayor, Marina del Pilar Avila Olmedo, published a video in social networks in which he claims that “these devices can remove up to 99 percent of viruses and have a duration of up to 72 hours”.
Chemicals can be harmful
In a statement, the Secretariat indicated that the concentration of the disinfectant could be insufficient to inactivate the virus. Even, the aerosol generated would facilitate the spread of the virus that may be present in the clothes, hair or belongings of the people who go through the tunnel, he noted.
In addition, the inhaling of substances such as disinfectants may cause damage to the respiratory tract, coughing, sneezing and irritation of the bronchi, and trigger asthma attacks. You can also produce chemical pneumonia, and irritation of skin, eyes and mucous membranes.
“These technologies could generate a false sense of security of the people and neglect of basic measures of prevention such as frequent hand washing, use of respiratory etiquette and to maintain a healthy distance.
“In conclusion, the Secretariat of Health does not recommend the use and dissemination of these technologies to be evaluated scientifically its effectiveness, as well as their risks and benefits,” he stressed.
