Deadly “CRE” family of superbug bacteria spreading more widely and stealthily, Harvard study finds
This really does highlight where markets fail as a mechanism.
New antibiotics need to be developed by publicly funded institutions, and kept for use in cases where all else has failed, and in every case, sterilisation procedures need to be used to eliminate as far as possible any remaining resistant bacteria (UV, strong oxidants like hydrogen peroxide or other strong bleaches, etc).
The current market incentives to sell as much as possible of the new product for use in animals is a very high risk for humanity as a whole.
And sure there are other therapy modalities that can contribute to probabilities of survival – like silver and vitamin C and fresh fruit and green leafy vegetables – that are not common in hospitals (hospital food is notoriously bad) and need to become the norm – and we do need effective drugs, for when all else fails – because in complex systems, it usually does from time to time.
