AMR is a Global Health Threat

Antimicrobial Resistance (AMR)  is life-threatening, costly and present in every country in the world.

Drug-resistant infections cost the US an annual $20 billion in excess healthcare costs and $35 billion in lost productivity. According to recent research, it's estimated that up to 160,000 in US die from antibiotic resistance per year and almost three-quarters of a million people around the globe annually; by 2050 that could grow to 10 million every year if the trend isn’t slowed.

Paratek is fighting the AMR pandemic.
