Coronavirus lifespan on different surfaces

The National Institute of Health (NIH) has published a study according to which a virus can survive suspended in the air for up to 3 hours. In the imagination of laymen, droplets fall coughing straight to the ground, which is particularly visible in daylight. But basically, there are microcapsules that protect the virus as a spacecraft and so behave in space.

It is important to realize that the virus can contaminate surfaces that have been dropped by breath drops when talking, sneezing, or coughing a person infected with the virus – and that person may not even know that they are infected. Droplets can land on the door handle, elevator buttons, or workbench to spread the virus to other people who touch them. Therefore, it is extremely important to wear a drape and minimize the number of contaminated surfaces. At the same time, it is necessary to disinfect these surfaces to prevent the spread of infection.

WEAR A MASK

Wear a disposable mask only once, and after returning home, fold it by grasping only the elastic bands. Never touch the front of the mask, which may be contaminated. Then dispose of the device in a closed basket.

If you have sewed the mask, also use it once, wash it at 60 to 90 ° C. After drying, iron it.

LIFESPAN ON SURFACES

Scientists have found that the virus survived the longest on stainless steel and polypropylene – a typical plastic used massively for the production of toys or car parts. It was present on these surfaces for up to 3 days. On the carton, however, the new coronavirus managed to hold for 24 hours. It was held on aluminum for 2 to 8 hours, in the case of latex for less than 8 hours. Therefore, we should be extremely careful on smooth surfaces. Handles and table surfaces are the best media for virus transmission.

These and similar tests are run under stable and controlled conditions. In normal environment conditions such as light, temperature, and humidity vary, and thus the survival time of the virus may change. For example, if a virus contaminates a window sill or a desktop that is exposed to the sun, it is unlikely to survive as long as UVA radiation has strong disinfectant effects.

BANKNOTES AND MOBILES

A textured surface with pores will trap the coronavirus and get stuck in it like a trap where it perishes much earlier. We are talking about fabrics, hair, and banknotes.

Coins have a higher potential for transmission of infection than banknotes, with many bacilli on their surface. Therefore, it is necessary to use hand disinfection after the payment or to wash them properly with soap at home.

The source of the virus can be a mobile phone. It must also be disinfected when we come from the outside.

Ideal if you use a wiping cloth moistened with a solution containing alcohol or cotton swab with disinfectant. Never spray the product directly on the machine to avoid damaging it.

How to protect yourself?

Follow all recommendations of official authorities – wear a veil (ensure its disinfection), limit social contacts. Keep a distance of at least 2 meters from others, do not touch the T-zone (eyes, nose, mouth), wash our hands frequently and thoroughly and disinfect the surfaces around us.

It is scientifically proven that coronaviruses, in general, can be eliminated from surfaces by traditional disinfectants that we use in the home. Disinfectants containing already 62% ethanol, 0.5% hydrogen peroxide or 0.1% sodium chlorate (ammonia) are able to effectively inactivate coronaviruses within one minute.

Disinfect all surfaces in the home that you frequently touch: kitchen countertop, dining table, chair backrests, electric switches, all handles and handles, toilets and washbasins, TV controls. When you get home, always wash your hands thoroughly, disinfect the door handle and then your mobile phone, which is your third hand, as well as other things that you normally carry and touch with your hands.
