Perhaps you should try some spelling variations:
public's health » public health, public wealth
publich health » public health, public wealth, public heath
public healthy » public health, public wealth, public heath
publick health » public health, ausblick health, public wealth

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((publich health) OR (public healthy))) OR (publick health))) OR (public's health)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((publich health) OR (public healthy))) or (publick health))) or (public's health))".
• Adding a wildcard symbol may retrieve word variants: ((((((publich health) OR (public healthy))) or (publick health))) or (public's health))*.
