As the world grapples with the ongoing COVID-19 pandemic, understanding the transmission and persistence of the virus has become crucial. One area of concern is the contamination of surfaces and the potential for the virus to survive on various materials. In this blog post, we will explore the persistence of COVID-19 on surfaces and examine the contamination levels associated with different objects.

How long can COVID-19 survive on surfaces?

Studies have shown that COVID-19 can remain viable on surfaces for varying periods, ranging from hours to days. The survival time depends on various factors, including the type of surface, temperature, humidity, and the presence of sunlight or disinfectants. It is important to note that the virus’s ability to infect a person diminishes over time on surfaces.

Which surfaces are more likely to harbor COVID-19?

COVID-19 can survive longer on certain surfaces compared to others. Studies have indicated that non-porous surfaces like stainless steel, plastic, and glass tend to retain the virus for a longer duration. Porous surfaces, such as cardboard or fabric, may allow the virus to live for a shorter period. However, it is crucial to maintain caution and proper hygiene practices, regardless of the surface type.

What are the contamination levels on commonly-touched objects?

While contamination levels can vary, here are some commonly-touched objects and their potential for COVID-19 presence:

  • Elevator buttons: High contamination level due to frequent contact.
  • Mobile phones: Moderate contamination level as they are often in close proximity to our face.
  • Supermarket carts: Moderate contamination level due to the number of people using them.
  • Doorknobs: Moderate contamination level as they are frequently touched surfaces.
  • ATM keypads: Moderate contamination level due to extensive handling.
  • Remote controls: Low to moderate contamination level based on usage frequency.

It is important to regularly clean and disinfect these objects to reduce the risk of transmission. Additionally, practicing good hand hygiene by washing hands or using hand sanitizers can further minimize any potential hazards.

How can we protect ourselves from surface contamination?

To protect ourselves from surface contamination, we can take the following precautions:

  • Frequently clean and disinfect commonly-touched surfaces using appropriate disinfectants.
  • Minimize direct contact with high-touch objects when possible.
  • Avoid touching the face after touching potentially contaminated surfaces.
  • Wash hands thoroughly with soap and water for at least 20 seconds, or use hand sanitizers with at least 60% alcohol content if soap is unavailable.
  • Follow local health guidelines and recommendations for preventing the spread of COVID-19.

By implementing these practices, we can significantly reduce the risk of contracting the virus from contaminated surfaces and help break the chain of transmission.

The persistence of COVID-19 on surfaces is a concerning aspect of the virus’s transmission. By understanding the potential contamination levels and taking appropriate measures to maintain cleanliness and hygiene, we can protect ourselves and others from the risk of infection. Stay informed, stay safe, and together we will overcome this challenging time.
