Research Reveals Currency Notes Could Cause Acne And Some Diseases

This research work is based on dollar but applicable to all currencies. 

The dangers of misuse of currency notes such as contact with the breast as some women do, rubbing the notes in the mouth and some other bad behaviours expose people to the dangers of contracting deadly illnesses as these notes have been found to bear some viruses.

As published by, the research read: 

Mom always warned: wash your hands after playing with money and never, ever put it in your mouth.

A logical life lesson, scientists, however, are using the data from various money-related research papers to silently track human activities, and what they have found makes mom’s warning pale in comparison.

One of these studies, released in April, “identified over a hundred different strains of bacteria on dollar bills circulating in New York City,” reports: 

Some of the most common bugs on our currencies included Propionibacterium acnes, a bacteria known to cause acne (pimple), and Streptococcus oralis, a common bacteria found in our mouths.

The research team, led by biologist Jane Carlton at New York University, also discovered traces of DNA from domestic animals and from specific bacteria that are associated only with certain foods.

Another similar study which recovered traces of DNA on ATM keypads “reflected on the foods people ate in different neighbourhoods”:

People in central Harlem ate more domestic chicken than those in Flushing and Chinatown, who ate more species of bony fish and mollusks. The foods people ate transferred from fingers to touchscreens, where scientists could recover a bit of their most recent meals.

But, of course, it’s not only food and germs we leave behind.

Traces of cocaine can be found on almost 80% of American dollar bills, while other drugs, such as morphine, heroin, methamphetamine and amphetamine, are less commonly found but do appear.

Scientists are using this data to understand patterns of disease through the so-called “molecular echoes” we leave behind.

They are also looking at ways to clean money between transactions:

Putting older bills through a machine that exposes them to carbon dioxide at a specific temperature and pressure can strip dollar bills of oils and dirt left behind by human fingers, while the heat kills microbes that would otherwise linger.
