COVID-19 virions are relatively poorly adapted to life outside the human body. However, the risk of contamination through surfaces is very high. The transmission of the new strain in this way was associated with an outbreak of infection on the Diamond Princess cruise ship, which was quarantined off the coast of Japan.

How active is the coronavirus in the air

Virions of the new strain, caught in the air when a sick person sneezes or coughs, are viable for 3 hours. The chance of infection is high in the first 66 minutes. After that, the activity of viral particles fades away, as does their ability to penetrate into a living organism. To minimize the risk of contracting coronavirus by airborne droplets, it is necessary to avoid large crowds. If you cannot do this, you should keep a distance from the other person at least 1.5 m.

How long does the coronavirus live on surfaces

A sick person, when touching objects, also leaves virions on their surfaces. On them, they are viable for several days. The pathogen particles are active for the longest time on stainless steel and plastic. They live on them for up to three days.

On steel, the so-called "half-life", when half of the particles die, is 5 hours 38 minutes, and on plastic - 6 hours 49 minutes. After this, the virions are weakened, but are still capable of infection. Particularly dangerous are the handles of doors and trolleys in stores, elevator buttons, handrails in transport and other elements that people most often touch. During a pandemic, it is advisable to use disposable gloves in public places.

On cardboard and paper surfaces, the coronavirus is tenacious for about a day. The half-life is about 3.5 hours.

On copper surfaces, the new strain is active for up to 4 hours, and half of the virions die in 46 minutes.

In cold water, particles of coronavirus can live up to 9 days, and when frozen, up to several years.

What to do

To reduce the spread of the virus, experts recommend disinfecting surfaces with various solutions. Frequent hand washing with soap and water is an obligatory measure, but it is effective only for a duration of at least 20 seconds.

Ultraviolet light kills a new strain in a few minutes. Alcohol and antiseptics are very effective against COVID-19 particles. These funds are good in the role of prevention of infection, so you should not neglect them during a pandemic. It is important that they contain ethanol or propanol. These two types of alcohols are more potent in deactivating virions. They easily dissolve the envelope of the viral particle, and in its absence, it quickly loses its ability to multiply. Antiseptics are effective if the alcohol concentration in them is at least 60%.

Perfume or eau de toilette can also cope with the role of a disinfectant. The amount of alcohol in them varies from 60 to 85%.
