“…Oral administration of 400 mg albendazole daily for 3 d is safe and 60-80% effective at curing S .stercoralis infections, and is currently recommended by World Health Organization guidelines (WHO, 1990). Mass chemotherapy can reduce community prevalence effectively (ARGUEDAS et al, 1975;GOULART et al, 1977), although chemotherapy targeted to risk groups, or given selectively to those with detected infections, might provide more economical alternatives. The significance of S.stercoralis infection as a public health problem needs to be assessed more accurately before these options for community control can be properly evaluated.…”

Stool samples from 880 residents in an urban slum in Dhaka, Bangladesh, were collected on 3 occasions over one year, and examined for intestinal parasites. Information on many potential risk factors for infection was obtained by questionnaire from a respondent in each household studied. In a crude univariate analysis of the data, several of the factors were found to be significantly associated with Strongyloides stercoralis infection. Most of these factors were co-variate with one another, and with poverty generally. Using MantelHaenszel x 2 tests to control for confounding effects of each variable individually, the following 4 factors remained independently associated with S .stercoralis infection: respondent's use of a community latrine rather than a private latrine, living in a house with an earth floor rather than a cement floor, being of Bihari ethnicity, and being 7-10 years of age. Implications of these results for the epidemiology and control of strongyloidiasis are briefly discussed.

“…Environmental and human behavioral conditions that co-occur with hookworm infections are such things as: moist, warm climates (tropics, subtropics and mines), human populations that defecate directly into soil, and not consistently wearing shoes. 4,13,14 In the Middle East, North Africa and Southern Europe, the species that occurs is Ancylostoma duodenale. In the Americas, Asia and Africa both A. duodenale and Necator Americanas are found.…”

Mapping of Historic US Hookworm prevalence data from the Rockefeller Sanitary Commission (early 1900s) using current GIS (Geographic Information System) software (county shape files) illustrates the extremely high prevalence of hookworm disease (Uncariasis) in the Southeastern US at the time. Some counties in 7 states recorded 50% to 100% of the population with positive screens for hookworm in a monumental surveillance and treatment campaign. Narrative descriptions mentioned higher prevalence in “sand districts” vs. “clay districts”. In order to validate this description for historic data, further GIS databases (STATSGO) were used to classify and quantify the % acreage in Eastern North Carolina falling into moderately- to well-drained soil types. These were then mapped and compared with the historic prevalence data. Most severely infested counties had at least 50% moderately to well-drained soil. Further analysis on soil data for other states with “coastal plains” could provide more background information on Environmental conditions for hookworm prevalence and distribution in US history. “Since history has no properly scientific value, its only purpose is educative. And if historians neglect to educate the public, if they fail to interest it intelligently in the past, then all their historical learning is valueless except in so far as it educates themselves”. Trevelyan, (1922).
