Pre-Medical?


It's not exactly a new story but WHO have reiterated their warning that the development of antibiotic-resistant strains of bacteria could 'return us to an age where even mild infections killed' (http://www.theguardian.com/society/2014/apr/30/who-calls-urgent-action-antibiotics-antimicrobial-resistance). People (especially the very young or the aged) in developed countries would die in increasing numbers from conditions like diarrhoea and pneumonia. It is problematic that a) bacteria, because of their rapid life-cycles and ability to transfer genes to each other, evolve very quickly; b) these infective agents are rapidly transported by air travel; c) there is still much overuse of existing antibiotics in medicine and farming (giving resistant strains opportunities to arise) and d) the incentives for pharmaceutical companies to work on genuinely new alternatives is limited (as any new items would have to be curtailed in their use to limit resistance development). WHO do suggest an increased role for improved hand sanitation but that seems a rather desperate ploy.
