Antibiotic resistance happens when bacteria develop the ability to defeat the drugs designed to kill them. It has now grown into a global public health issue. It was responsible for at least 1.27 million deaths worldwide in 2019, while being involved in nearly five million deaths. Every year, the U.S. sees almost three million antimicrobial-resistant infections, with the cost of treating the six most common ones at over $4.6 billion. The EU sees almost 700,000 cases each year, which cost it an estimated €1.5 billion.
