![]() ![]() I am a researcher who studies the evolution of antibiotic resistance. This results in increasing abundance of resistant bacteria that can undermine the effectiveness of the antibiotic. While bacteria that are more sensitive to the antibiotics are killed off, those that are able to survive will continue to reproduce with less competition. Instead, antibiotics spread across the body and inhibit or kill any sensitive bacteria they encounter. But antibiotics don’t just kill infection-causing bacteria or stay in the area of the body where the infection is occurring. Can washing your hands help stop the evolution of antibiotic resistance? Mathematically, it’s possible.Īntibiotics save lives by killing bacteria that cause infections.
