Today we are all experiencing difficulttime. Forced self-isolation, uncertainty in the economy, uncertainty about tomorrow. All these factors strongly affect our physical and psychological state. News and opinions (often contradicting each other) are falling upon us from all sides. It can be difficult to endure even for a healthy and emotionally stable person, but what can we say about ordinary people. In the wake of universal hysteria, dishonest entrepreneurs are trying to earn capital. And well, if they do not cause any harm to the physical health of a person. But there are times when we are frankly misled, playing on feelings of anxiety, uncertainty and confusion.
The reason for writing this article wasnews in which a spokesman for the Russian president came to a meeting with a chlorine dioxide-based virus blocker. This is not some kind of know-how, they are sold for a long time and around the world, but in the context of the declared pandemic, almost all Russian media drew attention to it. Let’s try to figure out what kind of blocker it is, why it was created, what helps from it, and whether you need to run to the pharmacy to buy it.
- 1 What is a virus blocker?
- 2 How the virus blocker works
- 2.1 1. What viruses the blocker was tested against
- 2.2 Is the virus blocker effective against coronavirus?
- 3 How to protect yourself from coronavirus?
What does a virus blocker consist of?
In terms of chemistry: chlorine dioxide has the formula ClO2 (chlorine about two). In its usual state, it is a reddish-yellow poisonous gas. If the ambient temperature is below 10 degrees Celsius, it turns into a liquid that, under certain conditions, can explode.
Of course, in blockers that are sold inThe pharmacy does not contain pure chlorine dioxide and will not be able to explode in the hands. It is stored in a sachet in the form of small balls in an adsorbed form. Silica gel is used as a sorbent. Also, chlorine dioxide can impregnate special paper or fabric.

Chlorine dioxide is used in many areas: for example, for bleaching paper or disinfection of materials; as components of toothpaste andmouthwash. Cases for use as a disinfectant during a coronavirus pandemic are also considered. The truth is to understand that disinfection occurs by spraying a substance (powder) on the surface.
By itself chlorine dioxide is poisonous and causes irritation of the mucous membranes (eyes, nose, throat), as well as coughing. Recently, chlorine dioxide is used in sewage treatment plants for water disinfection.
Now that we have begun to understand what active substance is in these blockers, we can tell you more about them.
How does the virus blocker work?
In fact, this is a small box the size ofa badge in which holes are cut so that gas is released from the balls saturated in chlorine dioxide (tissue, paper), which, according to the inventors' idea, should protect us from coronavirus infection. But there are two fundamental points that are worth paying attention to:
1. What viruses have the blocker been tested against?
Blockers were invented to counter influenza A virus and adenovirus. Moreover, they were even tested for effectiveness and showed a good result. Here are just one caveat:
Virus samples are sanitizeda closed desiccator - in fact, in a glass pan. Even assuming that a large desiccator with a volume of 10 l was used and an exposure of 5 minutes was effective against viruses, a similar effective concentration of chlorine dioxide for a closed room of 20 sq m with an air volume of 50 cubic meters (5 thousand times more than the desiccator) can be obtained in 25 thousand minutes, that is, in about 17 days, which far exceeds the indicated period of stability of viral particles both on surfaces and in aerosol drops
says an employee of Moscow State University Evgeny Shilov
In other words, to sanitize a small room with such a blocker need 2.5 weeks. During this time, the virus itself will order a long timelive and play in a box. And this is a very small room. The larger the room, the more time for disinfection. Needless to say, the effectiveness of using blockers in the open air tends to zero at all?
Is coronavirus virus blocker effective
And finally, the main thing. Today there is no researchthat would confirm the effectiveness of chlorine dioxide blockers from coronavirus. They simply did not.
And if today there are noevidence of the real effectiveness of these devices, it can do a lot of harm. In addition to the toxicity of the emitted gas (especially for people with hypersensitivity), it creates a false sense of security. The seller describes the product in such a way that it creates the illusion of complete protection against viruses and bacteria, which automatically leads us to carelessness and lower levels of security during forced contacts outside our home.
How to protect yourself from coronavirus?
Today, scientists around the world converge in a singlethe opinion that the best protection against coronavirus is maximum self-isolation. This is the only way humanity can defeat a pandemic and return to normal. When you see an advertisement for some medications, the first thing to do is consult a doctor. If this is not possible, you can find information about it on the Internet. Just be vigilant - do not trust one source, always double-check the information. And only then make a decision about the purchase and use.
Be healthy and careful!
