Showerheads harbor large numbers of bacteria, including some that could trigger lung diseases
Showerheads contain bacteria that could trigger lung infections - daily science news in short

Showerheads are not a very clean place, they contain several types of bacteria. A group of scientists found that the regions where pathogenic bacteria are most prevalent in showerheads are the same regions where nontuberculous mycobacteria lung infections are common.

The study surveyed households across the United States and Europe and found that the bacterial populations differ depending on geographic location, water chemistry, and water source. Households that received water treated with chlorine disinfectants had particularly high abundances of certain mycobacteria.

The study highlights a possible connection between mycobacteria in showerheads and lung diseases and could lead to new strategies to reduce exposure to such pathogens.
