Parasitic infections hit the health of low-income Black communities where states have neglected sewage systems

The story of parasite infection in the U.S. is two-sided.

On one hand, the U.S. has successfully controlled many parasite infections. Malaria is one of them.

In addition, advancements in sanitation infrastructure and household construction mean that many Americans do not generally have to worry about parasite infections.

But this national success is not complete, as demonstrated by the recent findings in low-income Black communities across the country.

Limited awareness of the continued threat posed by neglected intestinal infections has made it more difficult to identify and treat these diseases in the U.S. than in lower-income nations.

For instance, in many countries the drugs needed to treat hookworm infections cost mere cents, but in the U.S., where drug prices are unregulated by the federal government, these same medications can cost hundreds of dollars.

The recent court decision in Alabama represents an important step toward increased national recognition of the role intestinal infections play in perpetuating racial health inequities.

Increased awareness will ideally result in improved access to testing and treatment in affected communities. But more work is needed to assess the full extent of these infections across the U.S.

Even if medical treatment is accessible and affordable, vulnerable individuals are often reinfected, as these pathogens continue to spread through the environment. Structural changes are needed to break the cycle of infection and poor health.

Current federal investment in community infrastructure – including water quality – is encouraging but does not go far enough. Ultimately, a concentrated nationwide effort to update and maintain sanitation systems is the best way to finally halt infection transmission and support health equity across the U.S.
