Antibiotics have been used since their discovery in the 1920s to treat infections.
Now, there is concern that the use of antibiotics is making it harder to treat infections, as the bacteria may develop resistance over time.
Overuse and misuse are likely culprits in this resistance. Viral infections aren't helped by antibiotics, but many doctors prescribe them anyway.
Antibiotics are also used on animals in our food supply. That may contribute to antibiotic resistance as well.
What do you need to know about antibiotic resistance in animals and people?
Listen in as Dr. Christine Heaver discusses antibiotic resistance, as well as ways you can help reduce the growing problem.
