Parasitic Disease Diagnosis

DPDx: Laboratory Identification of Parasites of Public Health Concern provides information to health professionals on the identification and diagnosis of parasites. DPDx also contains parasite-specific information that may prove useful.

Drugs for Parasitic Diseases

Some drugs used to treat parasitic diseases are not approved (licensed) by the U.S. Food and Drug Administration (FDA) for sale in this United States since their demand in this country is so low and seeking approval is not cost effective for the drug manufacturers.

However, to allow treatment of patients with an unlicensed drug product, FDA may permit the use of a drug or biological product under an Investigational New Drug (IND) application. An IND application includes a protocol for the clinical use of the unlicensed drug and must be submitted for review to FDA and permitted to proceed before any agents are released under IND status. CDC maintains protocols with IND status for some drugs to ensure that they are available in the United States when needed.

The following anti-parasitic drugs can be obtained from CDC’s Drug Service (CDC Drug Service, Scientific Resources Program, telephone 404-639-3670):

  • Artesunate
  • Diethylcarbamazine (DEC)
  • Melarsoprol
  • Suramin
