I worked in Public Health for ten years, and we never ran short of issues: Teen Pregnancy is a biggie, can cost a community a lot of money. Immigrant health, PH is a major provider. Smoking Cessation, Cancer control and education. Bioterrorism is an emerging issue. Communicable Disease - TB is on the rise in a lot of communities. The possibilities are endless.
