Health Topics Index: A-Z

The Health Topics Index: A-Z provides information on some of the potential disease risks and exposures that may be encountered in a park and is intended to support National Park Service employees, volunteers, commercial use providers, and visitors.Take time to explore and learn more about the topics below which are listed in alphabetical order under the respective drop-down menu. New topics and information will be added as factsheets become available. If you have additional suggestions for health topics to include in the index, please let us know.

The information is not exhaustive nor is it intended to replace the information from other bureaus within the Department of the Interior or other expert federal agencies, such as the Centers for Disease Control and Prevention, the US Department of Agriculture, and the Environmental Protection Agency. In fact, we credit these agencies for much of the information, and links to their resources are often included at the bottom of each page. However, what these topics do try to do is: (1) condense large amounts of information to make it quickly and easily accessible; (2) provide clear instruction on specific actions to prevent and respond to these disease concerns in the national parks; (3) provide additional resources regarding case reports or investigations performed on NPS lands; and (4) place the disease information within the broad “One Health” context, which recognizes the interconnectedness of human health, animal health, and the environment.
