Unless otherwise noted, the articles of the our Website (www.ddhealth.org)--both text and graphics--are not copyrighted. They are in the public domain and may be republished, reprinted and otherwise used freely by anyone without the need to obtain permission from us. Credit to ddhealth.org as the source is appreciated but not required.

People are also free to link to any of our pages. Our preference is that people link to the material on the ddhealth.org site (rather than copying it to their personal Websites) because we continuously updates the information on the Website as better information becomes available.

If a person, nonetheless, decides to copy content or images, We strongly recommends that the copied item lists the date that the material was copied and provides a link back to its source. Users can then see for themselves if the copied material has been updated or changed.
