Chicken pox outbreak hits Kansas City Royals

While chicken pox -- a disease characterized by an itchy rash that normally progresses to red bumps and fluid-filled blisters -- is traditionally thought of as a childhood illness, adults who did not get the infection as kids and who have not received a vaccination are also susceptible. The disease affects adults differently than children, with adults more likely to have serious complications like pneumonia or infections such as staph, which in some cases can be deadly.
