It was not until 2012 when the World Health Assembly adopted the WHA65.21  resolution for the elimination of Schistosomiasis and increased monitoring and investment of surveillance systems. 

After 2001 Brazil was primarily the only country that reported data. However by 2020 Brazil, Venezuela, Suriname and Saint Lucia need to update the epidemiological status of Schistosomiasis that is officially present in their countries. Schistosomiasis was thought to have been brought to Palmares, Brazil during the slave trade from 1550-1646. It was likely that a group of escaped slaves allowed the parasite to proliferate as they harbored in the jungle region of Palmares. Since then the parasite has been ciculating throughout the continent. 

In 1975 the Special Program for Schistosomiasis Control (PECE) started to take steps in the direction of elimination. By 1993, after years of declining effort toward PECE, Schistosomiasis control was turned over to local government for surveillence. As with the other diseases in the project, local governemnts often marginalize poor and rural communites making it more difficult to recieve diagnosis and treatment. 

Schistosomiasis is a parasite that thrives in poor communties, especially communties that lack adequate comunity infrastructre such as access to healthcare or education along with water and sanitation systems. From numerous journals it was reported that a higher incidence rate occurs among  poor communities rather than in urban communities. 

Schistosomiasis perfectly outlines the equity difference in Brazil’s population. From the first transmission during the slave trade, Schistosomiaiss has always been a characteristic of poorer communities. During the 1960’s Fredrick Barbosa conducted a study on a community within Brazil experiencing a Schistosomiasis endemic and found that with improved water systems it greatly reduced the prevalence rate but along with providing education on sanitation and health, the community was more likely to see a decrease in the prevalence.
