Chicago doctor weighs in after Lake Tahoe resident tests positive for plague

California health officials have confirmed that a Lake Tahoe resident has tested positive for plague — a rare but serious bacterial infection most people associate with history books. The individual is recovering at home, but the case is raising questions about how often plague still appears in the U.S. and what precautions the public should take. Dr. Marielle Fricchione, an infectious disease specialist, joined ChicagNOW to help us understand the risks, the symptoms, and how people can protect themselves.
