Writes 100 word opinions with references  Part2 There are many public health issues in and out of the United States. In my opinion the top 5 issues are the healthcare systems in the United States, mental health, chronic diseases (diabetes, heart and cancer), drug overdose, and protection against looming diseases from other countries (CDC’s 7 public health, 2016).  Some of these issues were ranked as the top 7 according to the Centers for Prevention and Disease Control.
