In this program, experts from the Centers for Disease Control and Prevention, the World Health Organization, and elsewhere use case studies and research findings to discuss key issues in the war against infectious diseases such as pneumococcal meningitis, toxic shock syndrome, and ulcers. Decades of overuse and misuse of antibiotics are targeted as key factors in the birth of antibiotic-resistant bacteria and the reemergence of TB, bubonic plague, and other deadly organisms. Factors contributing to the spread of diseases, including crowded daycare facilities and international travel, are also examined, along with the development of the new drug Zyvox.
