Poor people in the United States are subject to a mostly ignored burden of diseases "caused by a group of chronic and debilitating parasitic, bacterial, and congenital infections known as the neglected infections of poverty." This is the "developed world" counterpart of neglected tropical disease, as they disproportionately affect impoverished and under-represented
minority populations. According to a report about to be published in PLoS Neglected Tropical Diseases:
The major neglected infections include the helminth infections, toxocariasis, strongyloidiasis, ascariasis, and cysticercosis; the intestinal protozoan infection trichomoniasis; some zoonotic bacterial infections, including leptospirosis; the vector-borne infections Chagas disease, leishmaniasis, trench fever, and dengue fever; and the congenital infections cytomegalovirus (CMV), toxoplasmosis, and syphilis.
These infections are concentrated in poor populations, among people of color, and in the American South with an epicenter around the Mississippi Delta, and in poor urban areas and along the US-Mexican border. Appalachia is another hot spot.
This report uses this this very interesting and alarming pair of maps, previously produced by the CDC:
Figure 1. Location of Counties That Represent Spatial Clusters in Which Poverty Rates Are at Least Two Standard Deviations Higher Than the National Mean. Top: Counties south of the Continental Divide. Bottom: Counties north of the Continental Divide.
There appear to be three important common features among the very long list of infectious diseases impacting these populations. From the report:
(1) their highly disproportionate health impact on people of color and people living in poverty;
(2) their chronic, largely insidious, and disabling features; and
(3) their ability to promote poverty because of their impact on child development, pregnancy outcome, and productive capacity.
It is also noted that while some of the studied diseases are exclusive to recent immigrant populations, most are not associated with immigration. The single most important determinant of these diseases is clearly stated in this report: Poverty.
Depending on which disease is considered, between tens and hundreds of thousands of people are affected. The paper's authors recommend:
...active surveillance (including newborn screening) to ascertain accurate population-based estimates of disease burden; epidemiological studies to determine the extent of autochthonous transmission of Chagas disease and other infections; mass or targeted treatments; vector control; and research and development for new control tools including improved diagnostics and accelerated development of a vaccine to prevent congenital CMV infection and congenital toxoplasmosis

I'd imagine one of the key driving factors is access to health care. Don't know much about the specific diseases listed but you'd think even with the same conditions of living, if more people were able to get treatment sooner rather than later a lot of the damage might be minimised.
Well, I think that some of those diseases can be treated with basic antibiotics. So is the problem with screening, or is that people don't have access to antibiotics (maybe because they can't afford them)? Either way, I agree with Michael's point because it seems like some of these diseases could be easily treated with basic health care.
I knew an MD who worked with Doctors without borders who was once sent to Louisiana. To train doctors. I am not making this up.
I'm going to pretend that DWB didn't actually send him, and that he was sent by some US federal or state healthcare agency, and just happens to also do work for DWB.
I'm also going to shout "LALALA I CAN'T HEAR YOU!" while covering my ears, if you say that wasn't the case.
It's hard to maintain composure otherwise. Some things are too sad to believe.
