Can you give a good topic sentence about public health effect in the community?

Understanding public health is often difficult because, when public health efforts are effective, there are fewer adverse events like illnesses or injuries to report.  In contrast, when public health efforts are not working, there is “news” about public health.  We hear about the obesity epidemic, the diabetes epidemic, lower life expectancies in certain communities, cancer clusters, or other topics that suggest a breakdown in public health.  Therefore, we tend to talk less about successful public health efforts than unsuccessful ones, which can lead people to believe that public health efforts are not successful.  This can make choosing a topic for a paper about the public health effect in a community more difficult.
