How Long Can the Virus Live on Surfaces?

For the past few months, researchers have claimed the coronavirus can survive up to four days on non-porous surfaces. But, now a study from Australia’s national science agency shows the virus can survive up to 28 days on surfaces and in the right conditions.

These surfaces include things like the glass on cell phones and other touch screen devices, stainless steel, and plastic banknotes.

Temperatures play a big role in this. It lived the longest – nearly a month – at 68-degrees Fahrenheit, room temperature.  The hotter it becomes the sooner the virus died.

This means that in winter the virus will be able to survive longer.

What Does This Mean for Research?

This is most important for stopping the spread and understanding how to fight this virus at home, especially in high contact areas. However, there are some caveats. This research was done in a very controlled environment with the most infection version of the disease. So, there are still a lot of questions that have to be answered.

How Should We Adapt To This New Information?

No matter what, the human-to-human spread is still the largest reason for transmission for COVID-19.  However, yes, it is possible to get sick if you touch a contaminated surface and then touch your mouth, eyes or nose.  So, Wash or sanitize your hands often. Wipe down frequently touched surfaces. And always disinfect public surfaces in the work place.
