The E. coli came from fecal bacteria, which can survive on hands and surfaces for hours.
Researchers from the London School of Hygiene & Tropical Medicine and Queen Mary, University of London looked at cell phones in 12 cities in the U.K.
They took 390 samples from cell phones and hands, which were then analyzed for germs. People were also asked about their hand hygiene.
The study found:
- 92% of phones had bacteria on them.
- 82% of hands had bacteria on them.
- 16% of hands and 16% of phones had E. coli bacteria, which is found in feces.
