Plans are already under way for developing a similar system to monitor TB disease in humans.

Geisinger Health System pediatric gastroenterologist William Cochran, M.D., has a personal and potentially life-saving message: Vaccines are not just for children any more. It's a message that resonates nationally as the CDC reports that since the 1980s, the number of reported pertussis cases has increased steadily, especially among adolescents and adults.
