Invest in health

Recent correspondence about hospital infection has understandably focused on the need for patients and visitors to maintain good standards of hygiene.

But there are surely many ways that technology could be applied to make our hospitals more sterile environments.

Given the vast financial cost of hospital-acquired infections I would imagine research investment running into millions, and funded by the NHS, would be money well spent if it could make inroads into this problem.

Whether this would take the form of some type of air filtration and recycling system, a coating that can repel or destroy infection, or a combination of the two, I do not know, but I am sure there is progress to be made given substantial investment and sufficient engineering resources.
