Several studies have looked at the lifespan of the new Coronavirus (COVID-19) on various surfaces. A study has indicated that the virus can live up to 24 hours on cardboard and up to three days on plastic and steel, another study suggests that the virus can survive up to nine days on certain surfaces. Scientists even found traces of the virus up to 17 days later on board the Diamond Princess! That is really scary. 

To be cautious, it would be a great idea to decontaminate everything you bring into the house, including item from the grocery store such as fruits and vegetables.

"It is not yet proven that we could get infected by putting our hands on something contaminated and then putting our hand to the face, but it is quite possible," said Normand Voyer, chemist and chemistry professor at Laval University, Quebec, Canada. 

If you wash your purchases with soap and water and then rinse them with clean water, it should remove all traces of the virus.

Simple regular dish soap is recommended, but avoid cleaning your fruits and vegetables with specialized products because they do not have what it takes to degrade viruses, they are mainly used to remove pesticides.

The professor explained: "What I do myself when I arrive with my grocery store is to first place everything in one place. Then I wash my hands, put soapy water in my sink and take a cloth to scrub everything that is wrapped and preserved."

For cardboard, as the virus is supposed to only live up to 24 hours, it is rather recommended to leave it in quarantine for at least 24 hours.

It is not advisable to leave your purchases in the freezer, because the cold does not kill the virus. He could even survive in these conditions for up to two years.

"What we know about coronaviruses from the past is that the more they are cooled, for example by putting them in the fridge, the longer they remain infectious," said Normand Voyer.
