Alert! "Disinfecting tents" and "disinfecting cabins" have been stopped!

To prevent and control the epidemic, all kinds of "hard nuclear weapons" have emerged.

Recently, a "mist-shrouded" "disinfection room" became web celebrity.

Recently, in a residential community in Rongchang, Chongqing, the property management set up a five-meter-long disinfection channel at the entrance, which was filled with machines spewing disinfectant mist.Residents walk through the see-through tent huts to get a dose of elixir and give their entire bodies a sanitizing "health care".

The inspiration is said to have come from a "pig farm"

Within days, "fairy huts" had spread across the country, including many cities in Guangdong province.

Is this "sanitizing cabin" really that magical?

Expert: "disinfect channel" harmful to human body

Not to mention that most people are not sick or asymptomatic carriers, even if the virus is inside the body, spraying disinfectant on the body will only work on those already dead or dying viruses in the clothes and hair.When the disinfection is over, the viruses that should be discharged during coughing and sneezing will still be discharged.

Zhu Zili, deputy director of the Shenzhen Center for Disease Control and Prevention's Institute of Disinfection and Vector Biological Control,The practice of this kind of epidemic prevention channel is more suitable for disinfection of articles, which is improper for disinfection of people and violates the basic principles of disinfection operation.

He expresses, average person holds the scale of disinfection specification very hard,if disinfection water concentration is too high, can burn skin, cause certain harm to upper respiratory tract system, disinfection water concentration is small cannot achieve the effect that kills virus again.

Disinfectants are basically disinfectants that contain chlorine,Such spray on the human body,it is easy to irritate the skin and respiratory tract, especially for asthma patients can even trigger asthma attacks.Not only kill the virus, but probably kill yourself too!

In addition, the length of disinfection time will also have a direct impact on the effectiveness of disinfection.According to professional guidelines, we use chemical disinfectants to spray disinfection, must carry out 'avoid people' operation, this is not contraband ".

Zhu suggested that to prevent and control infectious diseases, three steps should be adhered to:

First, strictly control the source of infection

Second, cut off transmission routes

Third, protect vulnerable populations

For the common people, the most important are the last two.

✎ Cut off transmission routes:

Pay attention to hand hygiene, wear masks, open Windows for ventilation and convection, and disinfect regularly at home and outside

✎ Protect vulnerable people:

It is necessary to take protective measures to prevent droplet.

Jinan has called off "disinfection channels" in residential areas

On February 9, the novel Coronavirus epidemic response headquarters in Jinan city, Shandong province "stopped" setting up a disinfection channel in the community and ordered the existing community to be removed immediately.

The Jinan Center for Disease Control and Prevention also gave an explanation---

① Chemical disinfectants can Kill you

Chemical disinfectants are highly irritating and can damage the respiratory mucosa in severe cases, leading to more susceptible to pathogens such as "novel coronavirus".

② Disinfectant can't be sprayed directly

The instructions for the use of disinfectants stipulate that when spraying the environment and the air, it must be done in uninhabited conditions.

The risk of someone inhaling or spraying disinfectant on a person during disinfection cannot be quantified.

③ Passing through the disinfection room for a few seconds has limited effect

The disinfectant must reach a certain concentration and disinfection effect to the specified time, in order to have a disinfection effect, in the very low concentration of aerosolized disinfectant through, disinfection effect is difficult to evaluate.

Guangdong CDC emphasized:

Chemical disinfectants shall not be used to disinfect the air (space) in the presence of human beings, and alcohols, quaternary ammonium salts, aldehydes and guanidine disinfectants shall not be used to disinfect the indoor air.

Novel Coronavirus should not be sterilized for the sake of disinfection. Only by using the right method can we better resist the virus oh ~~
