How long does the corona virus stay on surfaces?

In connection with the recently announced pandemic of coronavirus infection around the world, we have been increasingly thinking about ways and means to protect against this popular "wound". All types of medical face masks, antiseptic gels, regular hand washing and sometimes a complete cessation of visits to public places can be good infection prevention. But how long can a coronavirus be dangerous for a person outside of their body? In other words, can we get infected if we grab the handrail in public transport the day after a similar action by a person infected with a virus?

How long does the corona virus remain dangerous on objects?

After the coronavirus infection spread worldwide and even in people with a healthy nervous system the occurrence of a slight panic, more and more requests appeared in the network for ways to prevent a dangerous illness. In addition, one of the most exciting questions about the new subtype of the virus is its survival outside of the body, for example on surfaces, clothing, seats, coins, etc. Since it has long been difficult for scientists to answer this question clearly, they carried out a new study, in which the survivability of the virus was examined on different surfaces.

According to an article published in the Journal of Hospital Infection, studies have shown:

Corona virus remains contagious and dangerous:

Up to 3 hours in the air
Up to 4 hours on a copper surface
On clothes up to 12 hours
On cardboard up to 24 hours
On plastic and stainless steel – 2 to 3 days

Based on the data obtained, it can be assumed that with a handle on the door, together with a person infected with coronavirus, we run the risk of replenishing the number of people infected with the infection. Be that as it may, experts note that despite their ability to survive outside the human body, coronaviruses can easily be destroyed with household disinfectants.

High levels of humidity in the room (or on the street) where objects infected with the virus are located can extend survival by two.

Most likely, it won't work to get infected from a package from China unless you delivered it by courier service like DHL in 1-2 days. Most packages go to their recipients much longer than the corona virus. However, if cosmetics or other fluids were infected with the virus and then hermetically sealed, a package of such a fluid could theoretically be infectious for up to 4 days.

It would be a good idea to wear protective gloves and not to touch different surfaces in public places with your bare hands and not to lean clothes against possible carriers of the virus. But the most important thing is to wash your hands, not to touch your face and eyes with dirty hands, to leave shoes outside the apartment and to wash clothes at high temperatures.

Is Corona Virus As Dangerous As Everyone Says About It?

Hoping to find similarities to previous coronavirus subtypes that previously also caused human mass infection, specialists are continuing to investigate the general characteristics of the COVID 2019 viruses and the SARS and MERS viruses that caused the SARS epidemic in 2003 . Of course, the outbreaks of these epidemics did not have the scale and popularity that humanity faced at the end of the second decade of the 21st century. Thanks to the coronavirus subtypes already studied, scientists have many assumptions and ideas for their destruction. It is already known that previous corona viruses did not survive at temperatures above 30 degrees Celsius.

We have a publication on the website where we currently have all the important information about coronavirus. Answers to all questions about the virus.

Nevertheless, both for us and for scientists, the mechanism of infection through contact with people or various contaminated surfaces that we encounter every day when visiting shops, airports and public transport remains a mystery. It can be assumed that a person with dirty hands can rub his eyes or scratch his nose by pulling the virus onto the mucous membranes with a careless gesture. However, according to scientists, such an infection is not the main way to transmit a dangerous virus.

Close contact is considered to be the main and main method of transmitting person-to-person coronavirus infection, as small particles of saliva can reach the next person when coughing, sneezing, and even during less-than-emotional conversations. To prevent the spread of infections in everyday life, the World Health Organization recommends the use of medical masks that can at least partially prevent the infection if they do not stop completely.
