Coronavirus survives on surgical masks for up to SEVEN days

The video tutorial, published by medical specialists in Hong Kong, explores how long SARS-CoV-2 can survive on different surfaces and in various environments. Researchers applied virus culture droplets on surfaces like paper, wood, cloth, glass, and surgical masks. Results showed no virus on paper after 3 hours, on wood and cloth by day 2, and on glass and banknotes by day 4. Stainless steel and plastic were virus-free by day 7, but the virus persisted on the outer layer of surgical masks. The study concludes that while the virus is stable in many environments, it is susceptible to standard disinfection. Previous research indicated the virus can survive in air particles for hours and on surfaces for days.

Which surfaces were tested for the survival of SARS-CoV-2 in the study conducted by Hong Kong specialists?

• Only surgical masks and glass

• Various surfaces including paper, wood, and plastic

• Only cloth and tissue paper

• Only metal surfaces

After how many days was the virus undetectable on stainless steel and plastic surfaces?

• 10 days

• 7 days

• 4 days

• 3 days

On which surface was the virus still detectable after 7 days?

• Outer layer of a surgical mask

• Glass

• Wood

• Banknote

What does the research conclude about the stability of the virus in different environments?

• The virus is only stable in cold environments

• The virus is stable and cannot be disinfected

• The virus is stable but can be eliminated with standard disinfection

• The virus is not stable in any environment

According to previous research, how long can the novel coronavirus survive in air particles?

• Several hours

• Several minutes

• One day

• One week
