(CNN) — As the novel coronavirus outbreak continues to batter China, the country’s central bank has implemented a new strategy to contain the virus — deep cleaning and destroying potentially infected cash.
The new measures, announced by the People’s Bank of China on Saturday, aim to contain the spread of the virus, officially known as Covid-19. There is still a lot unknown about the virus, which has infected more than 71,000 people globally and killed 1,775, the majority in China — but it appears to survive for at least several hours on surfaces, according to the World Health Organization.
This is why buildings in affected areas are regularly disinfecting elevator buttons, door handles, and other commonly-touched surfaces — and why people are worried about cash, which changes hands multiple times a day.
All Chinese banks must now literally launder their cash, disinfecting it with ultraviolet light and high temperatures, then storing it for seven to 14 days before releasing it to customers, said the central Chinese government in a press release Saturday.
Cash that comes from high-risk infection areas, like hospitals and wet markets, will be “specially treated” and sent back to the central bank instead of being recirculated.
And in the central bank’s Guangzhou branch, these high-risk banknotes may be destroyed instead of merely disinfected, according to state-run tabloid Global Times.
To make up for the supply, the bank will issue large amounts of new, uninfected cash; in January, the bank allocated 4 billion yuan (about $573.5 million) in new banknotes to Wuhan, the Chinese city where the outbreak began, said the government press release.
Other measures includes suspending physical cash transfers between hard-hit provinces, to limit the possibility of virus transmission during the cash’s transit.
It’s unclear how “infected” cash in China may actually be — the virus likely dies after a few hours on surfaces, especially if it’s been killed with disinfectant. And most people in urban centers don’t use cash anyway — mobile payment apps are near-ubiquitous.
But as previous studies have found, money can be incredibly dirty. Each dollar, passed person to person, samples a bit of the environment it comes from, and passes those bits to the next person.
The list of things found on US dollar bills includes DNA from our pets, traces of drugs, and bacteria and viruses, according to a 2017 study in New York.
That doesn’t mean cash is actually dangerous for our health; disease transmission linked to money is rare, and no major disease outbreaks have started from our ATMs. But with new cases being reported every day in China, the country’s officials are taking no chances.
The new measures indicate “the financial system’s full support in fighting the virus and resuming production,” the government press release said.
China struggles to contain coronavirus
Since the outbreak began in Wuhan in December, it has spread to 28 countries and territories, sparking travel restrictions and emergency measures worldwide.
But mainland China remains the hardest hit. Of the 1,775 coronavirus deaths worldwide, only five occurred outside of mainland China. And of the 71,319 cases worldwide, 70,548 are in mainland China.
To limit the spread of the virus, Chinese authorities have implemented a number of other drastic measures including placing 60 million people under full or partial lockdown. People aren’t just afraid to touch money — just going outside risks infection, so many have stayed at home for the past few weeks, only venturing out to buy groceries.
Even when they do go out, they wrap themselves in protective plastic; travelers at a Beijing train station this week were seen wearing disposable plastic gloves, shower caps, full-face plastic visors, and even full-body plastic ponchos.
The lockdowns and halt in business have also taken a toll on the Chinese economy, with some warning that the outbreak could cost China $62 billion in lost growth. Experts warn that if businesses shut down entirely, unable to survive the prolonged suspensions, it could result in mass layoffs, unemployment, and housing foreclosures.
And so, millions of people are beginning to resume work — in the safety of their apartments, in what may be the world’s biggest work-from-home experiment.
Meanwhile, Chinese and international experts continue working together to learn more about the virus and contain its spread. On Sunday, a team of WHO and international experts arrived in Beijing for a joint mission with their Chinese counterparts, to analyze data and determine next steps for both China and the world.
