All assays for molecular, serological, morphological identification, or characterization of parasitic diseases—and Trichomonas susceptibility testing—at CDC are temporarily offline and turn-around time is delayed. Diagnostic testing through CDC is expected to resume soon. CDC offers consultation regarding other options in the absence of diagnostic testing at CDC for some parasitic diseases.
DPDx is a website developed and maintained by CDC’s Division of Parasitic Diseases and Malaria (DPDM) that uses the Internet to assist laboratorians and pathologists in the diagnosis of parasitic diseases, both in the United States and abroad. Please remember that DPDx will not respond to inquiries that are outside the goals and objectives of this website.

If you are a patient with a medical emergency, contacting CDC is not the proper way to get help. CDC is not a hospital or clinical facility; we do not see patients and are unable to diagnose your illness, provide treatment, prescribe medication, or refer you to specialists. Please see your health care provider or go to the nearest emergency room. We recommend that you view the CDC/DPD fact sheet on How to Find a Physician. This fact sheet has several links that might help you in locating a physician in your area.
If you would like information on parasitic diseases written for the public, please visit the DPDM website.
How to obtain health information:
- Please see if the subject of your inquiry is addressed as a fact sheet in CDC’s Alphabetical Listing of Parasitic Diseases or CDC’s Health Topics A-Z page.
- For general information on parasitic diseases, you may also want to contact local sources of health and disease information, such as a physician or health care provider, state or local health department, public or university library, or state and county medical association.
