An 8 year old girl with a recurring cough and bouts of bronchitis since birth was treated with an average of eight courses of antibiotics annually.

The symptoms were worse at night to such an extent that she often would jump into bed with her parents. The mother was concerned about the overuse of antibiotics and wondered whether the home was contributing to the problem.

Upon further inspection, the cause was arising from the 30 year old hand-me-down mattress the child had inherited and had slept on since she was a baby.

Testing revealed high numbers of bacteria, fungi and dust mite. Once the mattress was replaced, her symptoms immediately improved. To date she has only had two courses of antibiotics in the past four years.
