Coronavirus COVID-19 on items

Researchers warn that the coronavirus COVID - 19 can remain on the surface of objects for up to several days. We will tell you what items are especially worth paying attention to, because we touch them involuntarily.

How long does coronavirus stay on the surface of objects? - This question is asked by many people, trying to find the answer to the question: How to avoid or minimize the risk of coronavirus infection? See how long coronaviruses remain on the surface of objects.

Coronavirus - how long does it stay on the surface?

The answer to the question of how to avoid coronavirus infection is not simple, but the World Health Organization gives some recommendations. First of all: you should wash your hands often.

Another important recommendation is to refrain from touching the face in order to minimize the risk of transmitting coronavirus to the mouth or nose. However, this is not all. Researchers from two German research centers - the University of Greifswald University and the University of Bochum - analyzed 22 coronavirus studies to develop recommendations for infection prevention. Their work, published in the prestigious scientific journal Journal of Hospital Infection, is a summary of the facts gathered during two previous outbreaks of coronaviruses - SARS and MERS.

The analysis showed that on the surfaces of objects, depending on the material and conditions, human coronaviruses can last from 3 hours to even ... 9 days! The situation is saved by the fact that an effective way to disinfect the surface is to wash it with alcohol, in particular a solution of 62-71% ethanol for 1 minute.

Coronavirus on objects

Some objects are touched during the day unconsciously, often repeatedly, sometimes literally just before washing their hands, which can lead to the transfer of viruses and bacteria to their surface. We will show you what to pay special attention to.


A smartphone is, of course, an item that we unwittingly touch most often during the day. Basically, he still has some kind of case, so there are two points of contact with unwashed hands: the case and the screen. It’s good to know that the surface of our phone may be more dirty than ... a toilet. Therefore, it must be frequently disinfected.

Commercial refrigerators

When visiting grocery stores, thousands of customers touch the handles of commercial refrigeration and freezing equipment thousands of times a day to take frozen or chilled products from them.


When we check the time, we often involuntarily touch the clock, repeatedly transferring bacteria and viruses during the day to its surface. We also shoot it before training in the gym, before entering the pool, and sometimes after entering the house, literally before washing our hands. Therefore, it is worth rubbing it with an antiseptic from time to time.


Some people remove their engagement ring before washing dishes and washing their hands. This is mistake! Most jewelry materials are resistant to detergents, so when washing hands it is useful to decontaminate jewelry.


The WHO recommendations for the prevention of coronavirus infection clearly state: avoid touching the face. This point should be expanded to include hair, which during the day we often touch unconsciously. Hair jewelry, such as hairpins, should be regularly cleaned with an antiseptic.

ATM card

Even children know that dirty money. But still, few people remember that an ATM card can be just as dirty. During the day, we touch it several times, so there are a lot of bacteria and viruses on its surface.

City map

A city map is another subject that we touch on daily, and sometimes several times a day. In addition, we take it out in places of the highest intensity of viruses and bacteria, that is, in public transport. This is worth paying attention to.

Steering wheel

Car steering wheel is an item that we regularly touch with unwashed hands. Worse, viruses can linger on its surface longer because they like low temperatures. Therefore, you should regularly wipe it with wet wipes moistened with alcohol, and disinfect your hands with antiseptic liquid when entering the machine.

Car keys

Car keys and house keys are the last items that we touch before entering the house before washing our hands. It is worth paying attention to this and from time to time wipe them with wet wipes moistened with alcohol.

Dog leash

This is perhaps the least obvious subject in this comparison. Meanwhile, the script is very simple, banal. Returning home from work, we immediately, still in boots and a jacket, grab the leash and lead the dog out, and I only wash my hands after returning from a walk.

We hope that all of the above will help you keep
