Coronavirus Can Survive For 28 Days On Smooth Surfaces Such As Stainless Steel, Phone Screens, And Plastics


A recent study said Covid-19 (SARS-Cov-2) causative agent for novel coronavirus could last for 28 days on smooth surfaces like phone screens, mirrors, stainless steel handles, and different forms of plastics. Some previous studies concluded that it could only survive from 3 to 5 days. Still, the research conducted by the Australian agency CSIRO proves that novel coronavirus can survive loner than the flu virus.

The New Study On Covid-19 SARS-COV-2

According to the coronavirus’s newest study, it is not detachable before 28 days post-inoculation at 20 degrees C on surfaces like glass, polymer, and vinyl. The virus was isolated even after 28 days at 20 degrees C and remain infectious. It can survive more than the Influenza virus and remain infectious for more than expected. This could be a possible reason for the uncontrolled spread of coronavirus worldwide and become a threat to humanity.

The experiment is concluded in a highly controlled environment in the darkroom to eliminate the risk of UV light. After contact with a coronavirus positive patient, the virus can last for a month on the smooth surfaces. So, the only way to wipe these surfaces after making contact with any COVID positive patient and wash your hand regularly. They concluded that the Nobel coronavirus is a highly adaptive virus that can adapt to any environmental condition and start spreading.

The Result For Various Surfaces In A Room

  • No infectious virus can be recovered after 3 hours of incubation from printing and tissue papers
  • Less smooth surfaces like wood and clothes virus could not be detected after day one
  • Smooth surface is the most favorable surface for SARS_Cov-2 virus
  • Virus recovered from smooth surfaces like glass and doors on day 4 and 7
  • In the case of single-use masks, the virus is found on the outer layer

Coronavirus is sensitive to heat

The study strongly suggests that the virus cannot survive longer when the temperature is increased. Coronavirus will not survive more than 24 hours at 40 degrees C and just stayed only 5 minutes when the temperature rose to 70 C. It is also found that the virus is most stable at 4 degrees C and less than that. So, the result strongly suggests that the Nobel coronavirus has lower survival in temperature more than 20 degrees C, but it also depends on the surface type. The smooth surface is a more favorable condition than rough surfaces.
