Coronavirus Life Span: For How Much Duration It Stays On Surfaces and In Air?

coronavirus lifespan

Coronavirus outbreak is getting more and more dangerous where the world has come to a standstill. With more than 21 lakh positive cases and more than 144k deaths across the globe, this virus is getting widespread and is not going to end any soon.  Most of the countries are in lockdown currently which is necessary to curb the spread of this virus. 

Social distancing which is considered an effective means of reducing the spread of the infection should be followed by everyone strictly. This helps to stop getting infected by some other infected person. 

There are chances of a person getting infected of the Coronavirus by touching contaminated objects. Also, if the particles of the virus are blown in the air by the infected person when he has coughed or sneezed then also any person can get infected of the virus if he passes from that route.

Now, the question is what is the coronavirus life expectancy? For how long does it stay on the different objects, surfaces and in air. Today, we will walk through you across the life span of this virus so continue reading and make yourself know about it.  

How much is Coronavirus’s life expectancy on different objects?


Coronavirus lifespan on surfaces differs from one surface to another surface. The lifespan of this virus on a surface or object depends on the temperature, humidity and type of surface that it has landed on. 

For example, research shows that the virus stays for three days on steel and plastic. Three days is a long duration but experts say that there are very low chances of getting an infection by getting in contact with such contaminated objects and surfaces. 

It stays for one day on cardboard. Most of our items ordered on e-commerce sites are delivered in cardboard boxes only but there is not a cause of worry as there are also low chances of getting infected by touching it unless the delivery boy is positive and has coughed and sneezed and handled the box with contaminated hands. 

It stays on copper for only four hours which is comparatively very low as compared to other objects. 

When the COVID-19 lifespan was compared with that of the SARS coronavirus, it was the same in the case of steel and plastic. On cardboard, novel coronavirus (24 hours) lasted three times longer than SARS (8 hours). It is seen that as temperature and humidity increase in an environment, the lifespan of the virus decreases. 

There are so many things that we touch in our days like cardboard boxes, plastic bags, utensils, and so many other things. If we keep on thinking that this object will be having a virus on it, that object will be contaminated and so on… then we will get crazy for sure. 

Experts say that there are low chances of getting any infection by Corona by touching any object unless any infected person has come in contact with that object or surface and his cough or sneezing droplets have fallen on it. 

Also, we can remain safe by wearing the gloves a whole day around so there will be no worry even if we touch numerous objects and surfaces in the day. One can clean the objects and packages with disinfectant wipes as it will clean it and then it will be safe for us to use it.

Washing hands regularly with a sanitizer or with soap and water is considered the best prevention method, one must not forget that and should wash their hands immediately after touching any object or surface outside of their house. 

Even in the house, if any package or object comes from outside and if we touch it then one should immediately wash the hands.  

Coronavirus lifespan on air

If some infected person coughs or sneezes then the virus gets suspended in droplets (called aerosols). This virus can stay in the air for about half an hour and then it can settle down on any object or surface. 

This is a potential risk for the medical workers as they are in constant touch with the Corona patients and they can get infected by the aerosols traveling in the air. Medical workers wear protective gears and it can collect tiny droplets of the virus in it and when they take off these protective gear, it can get suspended in the air again. 

Also, common people like us can get infected by the aerosols of any Corona patient near our house or in our street so one has to be careful while we get out of our house. Not wearing masks is a very risky step and one should wear the coronavirus masks anytime we get out of the house. 

As per physics, an aerosol that is at the height of 6 feet will take 34 minutes to land down. This seems to be like a potential danger to people but it is not so. The virus will quickly disperse in air and with time its ability to infect others will sharply fall. 


So, here was an overview of coronavirus lifespan on surfaces and in air. Experts say that there is not much risk with this but one should definitely remain alert and prevent touching unnecessary surfaces, wash hands regularly and wear the mask while going outside. This will help to keep us safe from getting infected! Also For more details on COVID-19, visit Healthclubfinder.
