DENVER (AP) — Colorado health officials have confirmed six cases of vaping-related illness since the state announced its first case last month.
The state Department of Health previously announced four known reports before confirming two more Wednesday.
Officials say the illness has hospitalized four in Colorado and is affecting mostly young people who reported vaping marijuana, nicotine or both.
Health officials continue to urge people to quit vaping until more is known about what is making people sick.
Officials say the illness has been identified in 530 people in 38 states, including seven deaths.
Symptoms could include coughing, shortness of breath, chest pain, and fatigue and can worsen over a short period of time.
