By 1953 a Bilharzia Control Unit had been established within the Puerto Rico Department of Health and a snail control project was instituted in an attempt to disrupt the transmission cycle of the schistosome parasite. Considerable attention was given to the study of the ecologies of transmission foci in order to better understand the interrelationships among people, snails, and schistosomes. During the 1960s the useful but limited method of fecal sampling was replaced by the intradermal skin test using schistosome antigen. Three surveys using the intradermal test had been carried out by 1976. and they revealed a changing pattern in the prevalence of schistosomiasis on the island. The various control programs and social factors responsible for this shift are assessed in terms of their contributions to the total program of control. Unlike many other control programs, the Puerto Rican effort has not stressed chemotherapy but rather has relied on measures such as snail control, improvements in water supplies, and better sanitation. Since the initial intradermal test of 1963, prevalence of schistosomiasis has declined from 12% to approximately 5% in 1976. While undeniably successful, the continuance of snail control as a major factor in the total control program is questionable, as cost analyses indicate that new chemotherapeutic measures might do the job more quickly and cheaply than snail control.</p></div>","PeriodicalId":79263,"journal":{"name":"Social science & medicine.

Many uses of this same Asiatic-type, melanotic chicken (BB-BMC) are currently shared by Mayan language groups in Latin America. The arbitrariness of the cures, most of which relate to illnesses considered to be induced by witchcraft, linked with a distinctive biological entity BB-BMC indicates that the assemblage of traits qualifies it as valid for testing the diffusion model. I have found that Amerinds in Mayan language groups possess many more of these folk medicine traits than Amerinds in other language and cultural groups. Away from the Mayan hearth in Guatemala, fewer Chinese like medicinal traits are found; but the fact that the intervening cultures effectively lack knowledge of cures with BB-BMC suggests presence of the cures prior to the dispersal and separation of Maya speakers. The BB-BMC's presence from the Mexican-U.S. border to Southern Chile indicates that the lack of folkloric medicine using BB-BMC is not associated with its absence but with the lack of a belief system related to it. Since belief systems of these types have to be carefully taught, a connection with the peoples of what is now Southern China or Southeast Asia was likely in pre-Columbian times. Certainly the early Iberians with their fear of the Inquisition and of becoming bewitched on board ships would not have allowed BB-BMCs and curers on their vessels. They had to have arrived earlier from Asia, since chickens were given as gifts to Spaniards by the 1520s–1540s on contact in several places in North and South America.</p></div>","PeriodicalId":79263,"journal":{"name":"Social science & medicine.

Subsequently, the seven hospitals most widely known by the community are evaluated, using the elicited attributes and a one-to-seven scale, by all members of three random stratified samples of approximately 45 people each. Four similar important dimensions of hospital differentiation and evaluation are identified through the use of J. Douglas Carroll's INDSCAL model. A clear pattern of perceived relative utility of alternative hospitals, based on the four dimensions, is exhibited by the residents. However, utilization among alternative hospitals is found to be negatively correlated with expressed preferences. The power of community residents to choose is significantly limited through institutional and cultural, rather than financial, constraints.

Such cultures subsist upon a binary economic system based on cultivated carbohydrates and protein obtained from hunting and fishing. This model is called into question by evidence from fieldwork carried out among the Macusi Indians of northern Amazonia. The Macusi depend on maize, beans, and other vegetable proteins during the rainy season when water levels are high and fishing is unproductive. For the Macusi and many other riverine groups, fishing heavily outweighs hunting as an animal protein source. In an examination of several cultures in the South American tropical lowlands, it is found that vegetable proteins enter the diet during the rainy season. Wet season vegetable protein use may represent a selective adoption of maize and other Mesoamerican crops by tropical lowland groups, who use them to overcome seasonal scarcities of animal protein. Interpretations of the culture history of the South American tropical lowlands assuming an unimportant role for maize and other vegetable protein sources are challenged. The diversity of environments suitable for maize cultivation in the tropical lowlands of South America is stressed, along with the complex patterns of human adaptation to the tropical environment</p></div>","PeriodicalId":79263,"journal":{"name":"Social science & medicine.
