Scientists identified more than 600 viruses in samples taken from bathrooms in the United States. The viruses infect bacteria — not people — and scientists say they may provide more benefits than causes for concern.

No one showerhead or toothbrush bristle is the same, with US researchers finding a rich, diverse world of viruses living in biofilms coating surfaces in bathrooms across the US and Europe.

Scientists at one of the world's leading universities have found 'never-before-seen' viruses in our toothbrushes and shower heads, but fret not: it might actually be a good thing. The eye-opening discovery was made by a research team at Northwestern University in Illinois, USA.
