But we are not doing it. Why? Because we misallocate the founds.
Looking at the data (http://www.nejm.org/doi/full/10.1056/NEJMoa1306801) there were 721,800 what they call health care associated infections in 2011 (I couldn't find newer data). If the rate goes down at what the article suggest, (75%) then we will save 541350 people a year using this method whereas it would cost more than 1.8 Billion dollars to save the same amount of lives using the Against Malaria foundation.
This is almost 500 times as effective!
How do we get this knowledge to people who have 2 million dollars to spare?
