How long can coronavirus live on a surface

Before we get into the subject matter “How long can coronavirus live on a surface“, let us run through the background information about COVID – 19.

COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.

The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don’t feel unwell. Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty breathing should seek medical attention.

How long can coronavirus live on a surface?

Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

The New England Journal of Medicine just published a study that tested how long the virus can remain stable on different kinds of surfaces within a controlled laboratory setting. They found that it was still detectable on copper for up to four hours, on cardboard for up to 24 hours, and on plastic and steel for up to 72 hours.

But it’s important to note that the amount of virus decreased rapidly over time on each of those surfaces. And so the risk of infection from touching them would probably decrease over time as well.

 

According to WebMED – How long can coronavirus live on a surface?

Here’s a guide to how long coronaviruses the family of viruses that includes the one that causes COVID-19 — can live on some of the surfaces you probably touch on a daily basis. Keep in mind that researchers still have a lot to learn about the new coronavirus that causes COVID-19. For example, they don’t know whether exposure to heat, cold, or sunlight affects how long it lives on surfaces.

Metal
Examples: doorknobs, jewelry, silverware
5 days

Wood
Examples: furniture, decking
4 days

Plastics
Examples: packaging like milk containers and detergent bottles, subway and bus seats, backpacks, elevator buttons
2 to 3 days

Stainless steel
Examples: refrigerators, pots and pans, sinks, some water bottles
2 to 3 days

Cardboard
Examples: shipping boxes
24 hours

Copper
Examples: pennies, teakettles, cookware
4 hours

Aluminum
Examples: soda cans, tinfoil, water bottles
2 to 8 hours

Glass
Examples: drinking glasses, measuring cups, mirrors, windows
Up to 5 days

Ceramics
Examples: dishes, pottery, mugs
5 days

Paper
The length of time varies. Some strains of coronavirus live for only a few minutes on paper, while others live for up to 5 days.

 

If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

 

STAY SAFE
