Some people worry that cash may be spreading the coronavirus.
Earlier this year, both China and South Korea began sterilizing their bills using UV light or high heat before putting them back into use. They also quarantined their bank bills for 14 days in hopes that any lingering viruses would die off during that time.
Little is known about how long COVID-19 might survive on currency. Laboratory testing on influenza suggests viability lasts from one hour to one day without mucus.
However, viability in nature would depend on temperature, humidity and exposure to sunlight. Nothing has yet been done with COVID-19 survival on cash, though on other surfaces, COVID-19’s survival has again varied.
The Problem With Going Cashless
One proposed solution is going cashless, meaning using methods of money that are not paper or coins, such as debit cards or cryptocurrency.
Finally, there is little evidence that eliminating the use of cash would make a difference in the spread of COVID-19, nor do we have data to support that this virus maybe easily transmitted by any type of contaminated surface.

Support local journalism
Studies have shown that when local journalism disappears, government financing costs go up, fewer people run for public office, elected officials become less responsive to their constituents, and voter turnout decreases.
