Antimicrobial resistance is the broader term for resistance in different types of microorganisms and encompasses resistance to antibacterial, antiviral, antiparasitic and antifungal drugs.
Antimicrobial resistance occurs naturally but is facilitated by the inappropriate use of medicines, for example using antibiotics for viral infections such as cold or flu, or sharing antibiotics.
Resistance to antimicrobials (AMR) is a complex and growing, international public health problem. [1, 2] Globally, infections with resistant microorganisms are estimated to kill hundreds of thousands of people every year. An often cited but also criticized scenario suggests that by 2050 that figure could be more than 10 million. The economic cost will also be significant, with the world economy being hit by up to $100 trillion by 2050 if we do not take action. 
Formal policies on the global, regional and national level most often use six strategies to reduce antibiotic use:
However, currently these strategies appear to be insufficient, as for example demonstrated by the unchanged average European consumption rates of antibiotics during the years 2011 – 2014.  European statistics also show that there are significant differences between European countries which are not related to geographic or natural conditions and can only be explained by socio-economic factors (policies, values, competencies, …).  For example, in the UK in 2015, for the first time fewer antibiotics were being prescribed by GPs and clinicians across all healthcare settings than in 2014.  Nevertheless, the latest “EARS-Net data for 2016 show that antimicrobial resistance remains a serious threat to public health in Europe”.
