Discussion Overview

The discussion revolves around the use of copper surfaces in hospitals, particularly in relation to their effectiveness in killing viruses and microbes, including the coronavirus. Participants explore the practicality, maintenance, and cost implications of using copper compared to other materials like stainless steel, as well as the potential benefits in less diligent environments.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants question why copper, known for its antimicrobial properties, is not widely used in hospitals despite its effectiveness against viruses.
  • Others argue that the high cost and maintenance requirements of copper surfaces may not justify their use in environments where strict disinfection protocols are already in place.
  • Concerns are raised about copper's tendency to corrode over time, which could reduce its effectiveness and increase maintenance costs.
  • Participants discuss the potential for copper to be beneficial in areas with lower diligence in hygiene practices, although some express skepticism about its practicality and cost-effectiveness in such scenarios.
  • There is mention of alternative materials, such as stainless steel, which require less maintenance and are more commonly used in hospitals.
  • Some participants bring up the historical use of copper in other applications, such as marine paint and plumbing, to highlight its antimicrobial properties.
  • Questions are raised about the effectiveness of combining copper with silver for enhanced antimicrobial properties.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the use of copper in hospitals. There are multiple competing views regarding its practicality, effectiveness, and cost compared to existing disinfection methods and materials.

Contextual Notes

There are unresolved questions regarding the specific maintenance protocols required for copper surfaces and the timeline for corrosion. Additionally, the discussion touches on the challenges of implementing new materials in established medical facilities.

I think I would use the word "partially" instead of "majorly" in this sentence, since I think the latest thinking is that airborne transmission is also a main mechanism, no?

The transmission of the SARS-CoV-2 Coronavirus is majorly through touching the contaminated surfaces and then the vulnerable mouth and eyes besides the direct contact with the infected person.

As far as I’m aware, the current received wisdom is that the main mode of transmission is prolonged (> 15 min) close (< 3m) contact. Surfaces and airborne transmission are less of a concern unless there is poor ventilation. The mantra I keep hearing is wear a mask, 6 feet (2 meters) distance, get outside.

Sorry, but could you please link a picture of that machine or something? I'm not really familiar with this context and could not put together the pieces.

If you had a flying saucer shaped disc that came into contact with gaming chips would this be a viable product to kill microbes/bacteria the gaming chips would be in a tumbler with constant replacement on a roulette table?

This thread seems to have as its basis that copper has some magic germicidal properties, and the merest touch of copper will instantly sterilize an object. It doesn't work like that.

Yes, microbes don't do well on copper surfaces, and after hours they may even die.
