Medical professionals of CC, does FIAT pose an increasing risk to microbial epidemic?

Qualifying statement: No medical background upon from reading sources provided. I also am aware not all bacteria is harmful and in cases necessary for ecosystem health.

US Flu Season will cost 9 Billion in economic damage It prompted the question what does that look like not just in paid sick leave but global opportunity costs lost.?

2003 Societal cost of flu was statistical estimate of 87 Billion in US

The WHO continually releases statements on the increased risk of antibacterial resistance at unprecedented levels can realize deadly consequences

Purpose of this post? Perhaps a serious narrative on the value of a digital currency needs to include the unnecessary risk FIAT has globally and the economic and health consequences with increased population and microbe distribution. I have not seen this topic typically discussed in the value of using digital currency. Last source on this, 94% of US bills tested had bacteria contamination

I am not trying to be hyperbolic suggesting that FIAT needs to be abandoned solely on potential health risk mitigation but I believe as a community education on this would benefit adoption of CC.
