Neglected Parasites
The Centers for Disease Control and Prevention (CDC) is responsible for identifying public health priorities in the United States and developing strategies to address areas of concern. As part of this mandate, the CDC has officially identified five parasitic diseases it considers to have been neglected (i.e., not adequately studied). These neglected parasitic infections (NPIs) include toxoplasmosis, Chagas disease, toxocariasis (a nematode infection transmitted primarily by infected dogs), cysticercosis (a disease caused by a tissue infection of the tapeworm Taenia solium), and trichomoniasis (a sexually transmitted disease caused by the parabasalid Trichomonas vaginalis).
The decision to name these specific diseases as NPIs means that the CDC will devote resources toward improving awareness and developing better diagnostic testing and treatment through studies of available data. The CDC may also advise on the treatment of these diseases and assist in the distribution of medications that might otherwise be difficult to obtain.
Of course, the CDC does not have unlimited resources, so by prioritizing these five diseases, it is effectively deprioritizing others. Given that many Americans have never heard of many of these NPIs, it is fair to ask what criteria the CDC used in prioritizing diseases. According to the CDC, the factors considered were the number of people infected, the severity of the illness, and whether the illness can be treated or prevented. Although several of these NPIs may seem to be more common outside the United States, the CDC argues that many cases in the United States likely go undiagnosed and untreated because so little is known about these diseases.
1. What criteria should be considered when prioritizing diseases for purposes of funding or research? Are those identified by the CDC reasonable?
2. What other factors could be considered? Should government agencies like the CDC have the same criteria as private pharmaceutical research labs?
3. What are the ethical implications of deprioritizing other potentially neglected parasitic diseases such as leishmaniasis?
