“…In the Mato Grosso, a level of parasitism similar to that observed at Trois Sauts has been reported for the Iaualapiti Indians. In addition, the same two specific features were reported: very low levels (almost zero) of Trichiuris trichiura and frequent low parasite loads (Ferreira et al, 1991). …”

Summary :Intestinal parasitism and its epidemiological characteristics were studied in an isolated Amerindian population from Upper Oyapock (French Guiana) that has retained its traditional social and cultural specificities. This population consisted of 138 Wayampi Indians, 68 adults and 70 children (below the age of 15 years), with a sex ratio (M/F) of 0.86, spread over the four villages of the community of Trois Sauts, corresponding to more than two thirds of the population recorded as inhabiting the sector in the last census (375 inhabitants). Fecal examination combined the direct examination of fresh feces with the quantitative techniques of Kato-Katz method, Baermann and MIF staining. Overall, 92 % of the subjects were found to have intestinal parasites, 85 % if only direct examination of fresh stools was taken into account. Fourteen species of human parasite were identified: seven protozoa and seven helminths. We observed in particular 1) a high frequency of hookworm infection due to Necator americanus. Over 50 % of subjects were affected, with a range of 25 % to 75 % according to the village, but with only moderate parasite loads; 2| a high level of parasitism by E. histolytica/E. dispar (17 %), Stongyloides stercoralis (16 %) and Hymenolepis nana (18%) ; 3) a lower level of parasitism by Ascaris lumbricoides and very low levels (almost absent) of Trichiuris trichiura ; 4) the absence of Schistosoma and fluke eggs. With the exception of H. nana, which was more frequent in children than in adults, there was no significant difference in the level of parasitism according to sex and age. Although the Wayampi of French Guiana are French citizens and consequently have quite high incomes and ready access to clinics and medicines, intestinal parasites are far from under control in this population. A lack of fecal hygiene and the habit of walking barefoot are widespread in the unchanging Amazonian environment and contribute to this phenomenon.KEY WORDS : intestinal parasites, epidemiology, Amerindians, French Guiana.

“…The available data on the frequency of E. vermicularis was derived from 25 studies that employed more than one technique, each based on different methodological principles 3 , 12 - 14 , 20 - 22 , 25 , 29 , 32 - 47 . Conversely, 29 studies utilized a single technique, either in isolation or in conjunction with helminth larvae concentration techniques 4 , 5 , 7 - 11 , 15 - 19 , 23 , 24 , 26 - 28 , 30 , 31 , 35 , 48 - 56 .…”

“…The highest frequency of E. vermicularis was found in samples collected in 1987 from the indigenous population of Xingu Park in Mato Grosso, with a prevalence of 26.1%. These samples were analyzed using sedimentation in water and sodium chloride solution floating techniques 32 . Despite employing similar diagnostic methods, other studies conducted in Rondônia and Mato Grosso do Sul on samples from indigenous populations reported a significantly lower frequency of E. vermicularis (2% and 3%, respectively) 4 , 38 .…”

Enterobius vermicularis, an intestinal helminth, is transmitted through the ingestion of eggs found in food, water, dust, or other fomites, including infected individuals. This review aimed to examine the frequency and distribution of E. vermicularis infections in Brazil between 1991 and 2022. The conducted bibliographic survey revealed that the frequency of E. vermicularis infections in Brazil ranged from 0.1 to 26.1%, depending on factors such as population ethnicity, individual age group, geographic area, time frame, and diagnostic method. However, these findings were based on a limited number of publications, suggesting that the actual prevalence rates of E. vermicularis infection may still be unknown and potentially underestimated.

“…In some indigenous communities, researchers have identified prevalence rates of intestinal helminths as high as 90% [40]. The diseases caused by a scarcity of clean water are the principal causes of morbidity and mortality for indigenous populations [38].…”

Prevention, control, and elimination of neglected diseases in the Americas: Pathways to integrated, inter-programmatic, inter-sectoral action for health and development

BackgroundIn the Latin America and Caribbean region over 210 million people live below the poverty line. These impoverished and marginalized populations are heavily burdened with neglected communicable diseases. These diseases continue to enact a toll, not only on families and communities, but on the economically constrained countries themselves.DiscussionAs national public health priorities, neglected communicable diseases typically maintain a low profile and are often left out when public health agendas are formulated. While many of the neglected diseases do not directly cause high rates of mortality, they contribute to an enormous rate of morbidity and a drastic reduction in income for the most poverty-stricken families and communities. The persistence of this "vicious cycle" between poverty and poor health demonstrates the importance of linking the activities of the health sector with those of other sectors such as education, housing, water and sanitation, labor, public works, transportation, agriculture, industry, and economic development.SummaryThe purpose of this paper is three fold. First, it focuses on a need for integrated "pro-poor" approaches and policies to be developed in order to more adequately address the multi-faceted nature of neglected diseases. This represents a move away from traditional disease-centered approaches to a holistic approach that looks at the overarching causes and mechanisms that influence the health and well being of communities. The second objective of the paper outlines the need for a specific strategy for addressing these diseases and offers several programmatic entry points in the context of broad public health measures involving multiple sectors. Finally, the paper presents several current Pan American Health Organization and other institutional initiatives that already document the importance of integrated, inter-programmatic, and inter-sectoral approaches. They provide the framework for a renewed effort toward the efficient use of resources and the development of a comprehensive integrated solution to neglected communicable diseases found in the context of poverty, and tailored to the needs of local communities.
