We look into the latest news on an outbreak of severe lung disease among users of electronic cigarettes that continues to spread to new patients and states. The CDC recently announced that there are now 530 confirmed or probable cases of lung injury associated with vaping, a jump from 380 cases reported last week. The CDC has stepped up its investigation and activated its Emergency Operations Center in an effort to determine the cause of the illnesses, which (as of this post) still remains unknown.
