Experts at the Centers for Disease Control and Prevention say overuse of antibiotics is causing resistant bacteria to multiply and make people sicker. Infectious-disease specialist Dr. Gail Reid says many people don't realize how dangerous it can be to misuse antibiotics. She says sometimes people don't finish their medications and then try to use them when they have already expired.
Dr. Reid says people don't need to look for antibiotics for most sore throats, colds and even bronchitis. They usually go away on their own. The C-D-C says overuse of antibiotics in farm animals also contributes to the proliferation of so-called "superbugs."
