Explore the public health implications of increasing bacterial resistance to antibiotics, in this video from FRONTLINE: Hunting the Nightmare Bacteria. Two doctors explain that, while antibiotics have helped protect people from infections since becoming widely available after World War II, this unique class of drugs is losing its effectiveness from overuse. The more exposure bacteria have to an antibiotic, the more likely they will develop resistance to the antibiotic. Because as much as half of all antibiotic use in the United States is either unnecessary or inappropriate, more and more people may die of infections that were once easily treatable. This resource is part of the FRONTLINE collection.

We’re moving into a person-centric world where people and medical providers have access to genetic data. When a person's genome is sequenced, the known differences can help doctors predict their risk for disease, whether or not they are a carrier of a disease, and what their ancestry is. That data can point more directly to which treatments will work based on their genetic profile. Ultimately, this data could help medicine to move away from a treatment-based approach to a preventative model.
