Can the new coronavirus be disinfected with alcohol? What kind of alcohol is best for disinfecting the new coronavirus?

We all know that the new coronavirus is a more difficult infectious virus. It can survive in the air for a long time. Therefore, we must do a good job of disinfection and protection, and clean frequently to reduce viral infection. So can the new coronavirus be disinfected with alcohol? Let's take a closer look!

Can alcohol be used to disinfect the new coronavirus?

Some experts pointed out that 75% alcohol can effectively inactivate the virus. But at the same time, it should be noted that alcohol is flammable and explosive. Now that people store and use a large amount of it, they must pay attention to the fire hazards caused by alcohol.

Notice:

75% concentration is the best. Do not spray alcohol on infants and adults in large quantities to prevent alcohol allergies. Be careful with open flames to prevent fires.

75% concentration alcohol cotton pads or alcohol can not only kill viruses, but are also cheap.

If the alcohol concentration is too high (for example 90%), it needs to be diluted to about 75% before use, otherwise it will not be able to effectively kill the virus.

How to do it:

Use directly. Mobile phones, remote controls, computer keyboards, and various electrical switches and buttons can be disinfected with it.

Precautions for alcohol disinfection

1. Before using alcohol, clean the surrounding flammable and combustible materials, and do not spray it directly in the air. Alcohol has a low ignition point and is easy to self-ignite when exposed to fire or heat. When using it, do not get close to heat sources and avoid open flames. To disinfect the surface of electrical appliances, turn off the power first and wait for the appliances to cool down before proceeding. If you use alcohol to wipe the kitchen stove, turn off the fire source first to prevent alcohol evaporation from causing explosions. When using it, the container must be closed immediately after each use, and it is strictly forbidden to leave it open.

2. When using alcohol, you need to ensure indoor ventilation. Used towels and other cloth cleaning tools should be washed with plenty of clean water and stored in a sealed container, or placed in a ventilated place to dry.

3. It is not advisable to stockpile large amounts of alcohol at home. You can buy small bottles of alcohol, just enough for your use, to avoid fire safety hazards.

4. Store away from light to prevent tipping and damage. The container for alcohol must be reliably sealed. It is strictly forbidden to use uncovered containers. Avoid storing in glass bottles to prevent falling and damage. Do not store the remaining alcohol at home in a hot environment such as the balcony or stove, or near power sockets, walls, or table corners to prevent accidental tipping. It can be stored in a cool place such as a cabinet away from light. When storing, the lid must be tightly closed and the label must be affixed to avoid volatilization.

5. Alcohol should be kept out of the reach of children. For older children, parents can explain the properties of alcohol to their children and teach them not to play with alcohol, let alone light it with fire.

5 things the new coronavirus is afraid of

1. The new coronavirus is afraid of high temperatures

Scientists have been working day and night to find out that the new coronavirus cannot withstand high temperatures. They survive well at low temperatures, but once the temperature reaches above 56 degrees, they will not be infectious. At this high temperature, the virus will be completely killed in just 30 minutes. So if you want to prevent it, remember to cook food thoroughly before eating.

2. The new coronavirus is most afraid of high concentrations of alcohol

The new coronavirus will quickly lose its activity in alcohol above 75% and chlorine-containing disinfectants and will no longer infect humans.

3. The new coronavirus is afraid of ultraviolet rays

We all know that ultraviolet rays can achieve a certain disinfection and sterilization effect. This method also applies to the new coronavirus. As long as the virus is exposed to ultraviolet rays for 10 minutes, it can be completely eliminated.

4. The new coronavirus is afraid of leaving the host

The new coronavirus can only survive and divide inside the host. If it leaves the host and is exposed to the air, it can only survive for about two hours. Compared to the influenza A virus, which can survive in the air for 24 hours, the time required is much shorter.

5. The new coronavirus is afraid of strong immunity

Among the patients with the new infection, there are more middle-aged and elderly people over 40 years old. Among the deaths, there are many elderly people with poor immunity and chronic medical history. As long as we improve our body's immunity, the virus will be driven out under your strong immune system.

How to prevent the new coronavirus

Take good isolation measures: This is a measure proposed by Academician Zhong Nanshan after studying the characteristics of the new coronavirus. It has been proven that this is a very effective method. In particular, do not go to crowded places. At present, most people have been isolated at home for a period of time. If they persist for a while, they will get good results.

If you must go out, be sure to wear a mask, especially when going to crowded places such as hospitals and stations. Masks can effectively isolate viruses in the air.

Do a good job of disinfection: We need to disinfect key areas in the home and office, such as door handles, remote controls and other tools, as well as bathrooms, toilets and other places. Generally, wiping or spraying with 75% medical alcohol is sufficient. Be sure to wash your hands when you get home from going out, and then disinfect with alcohol. It is also best to spray alcohol on coats, etc., or irradiate them under ultraviolet light.

In addition, you must pay attention to improving your immunity. Why do some people have mild symptoms while others are in critical condition or even die when they are infected with the new coronavirus? The main reason lies in the different levels of immunity.
