Antibiotics have been used to treat a wide variety of illnesses some of which could possibly lead to death.

Some reasons for the widespread use of antibiotics include: increasing global availability over a period of time and uncontrolled sale in many low or middle income countries, where they can be obtained over the counter without a prescription. In Alexander Flemings Noble Peace Prize acceptance speech he also spoke of the danger of Antibiotic Resistance.
