From Public Health Resources:
This is a collection of links to get you started in researching information about the public health issues raised by your problems. Resources are presented in broad categories. You will want to use additional resources (HealthLinks, web, colleagues, fellow students, etc.) to find more information specific to your needs.
Additional information about the medical or clinical aspects of the problems may be located using resources such as MedlinePlus (which is also useful for health issues for specific populations), textbooks (print or online), or PubMed searches.
