[Trichuriasis in Cuba].

A representative sample of the Cuban population (11,364) is studied by using Willis and direct coproparasitological techniques. It was found that Trichuris trichiura is the most prevailing intestinal parasite (17.8%). A higher frequency of this kind of geohelminthiasis in people living in Cuban rural zones is seen. A prevalence peak is found in ages from 6 to 9 years, and a higher association of parasitism was found in those with worst hygienic and sanitary conditions.

[Sampling procedure for a survey of an interventional study on acute respiratory infections].

A description is made of the methodology used for obtaining a sample made up of 500 children under 5 years and 500 adults 65 year old and more, in order to carry out an intervention study on acute respiratory tract infections in an urban zone in Havana City and in a rural zone in Matanzas province, where different intervention stops will be taken with regards sanitary education about management of acute respiratory tract infections for the population and training for primary care medical personnel. We show the way the selected sample fits was planned with a very homogeneous distribution in the 8 areas under study, which allows for great reliability in the results.

[The infectious etiology of acute diarrheal diseases in the Republic of Cuba, 1991].

This study was carried out in 1991 to learn the behavior of enteropathogenic agents causing acute diarrheal diseases in Cuba. 30 children, admitted in hospitals or seen in outpatient services for acute diarrheal diseases, were selected in each province taking into account that they had not received antibiotic or chemotherapy treatments in the previous 72 hours. Feces samples were taken from all patients for virological, bacteriological, and parasitological studies, and results were sent to the Pedro Kourí Institute of Tropical Medicine. Data were processed in DBASE III. Higher positivity indices were attained in the winter months. The causative agents most frequently found were: rotavirus (8.2%); Entamoeba histolytica (6.1%); and Salmonella (4.2%). Escherichia coli, Campylobacter, Shigella and rotavirus showed higher indices in winter. Shigella flexneri and Shigella sonnei predominated. Salmonella serogroups D, B, and C, and enteropathogenic Escherichia coli 0119 and 026 subsets were the most frequently found.
