How long Coronavirus survive on surfaces

According to studies conducted by researchers from Princeton, National Institutes of Health, UCLA, the Virus remained virulent 8 hours on copper, 24 hours on cardboard, up to two days on stainless steel, up to three days on plastic.

 

The researchers compared two strains of the virus.

  • In red SARS-CoV-2, the virus responsible for Coronavirus disease.
  • In purple, SARS-CoV-1, responsible for SARS epidemy in 2003.

The Y-axis indicates the Viral Load, the number of infectious particles per mL. The viral load is considered ineffective below the dottet line, as to say that the body’s immune system should be able to handle it, if its not weakened by other factors.

X-axis indicates time in hours.

Results show that the Virus remained virulent around 8 hours on copper, up to 24 hours on cardboard, up to two days on stainless steel, up to three days on plastic.

As you wash your hands, don’t forget to wipe down surfaces also.
