In their recently released report, Antibiotic Resistance Threats in the United States, 2013, the US Centers for Disease Control and Prevention (CDC) provided a comprehensive review of antibiotic resistance in the US. In Section 1 (page 28) of the report, the CDC surveyed the literature on reports of resistance to specify the earliest date in which bacterial resistance to some of the key antibiotics were reported.

For this visualization, we use CDC data to identify the dates of emergence of the first cases of resistance against key antibiotics. We use bar charts to show the amount of time taken for bacteria to develop resistance to the antibiotics following their introduction to the US market. We have also highlighted the bacterial pathogens that were reported as being the first to develop resistance.
