Antibiotic resistance: how has it become a global threat to public health?

A 2013 report from the Centers for Disease Control and Prevention (CDC) revealed that more than 2 million people in the US alone become ill every year as a result of antibiotic-resistant infections, and 23,000 die from such infections.

In April this year, the World Health Organization (WHO) published their first global report on the issue, looking at data from 114 countries.
