ABSTRACT
An epidemiological and clinical study of criptosporidiosis in children from Ciego de Avila province was carried out from 1987 to 1994. During this period 14,895 children with acute diarrhea were studied. Cryptosporidium sp. oocysts were found in the feces of 1,256 (8.4 percent) of them. Isolated cases prevailed over outbreaks, being the incidence rate proportional in both urban and rural areas. Seventy nine point seven per cent of infected children were less one year old, predominating the age group 6-11 months old. No influence of seasons on the occurrence of the parasitose was observed. The most frequently detected symptoms and signs were diarrhea, vomits and loss of weight. The main epidemiological factors were: 8 1.0 percent of ill children drank water directly from the aqueduct, 12.8 percent lived in overcrowded conditions, 1 1.0 percent had animals and 10.7 percent attended nursery schools

Se realizó un estudio descriptivo de casos, en éste se investigaron 781 sueros con la técnica de inmunofluorescencia indirecta con antígenos de Babesia bovis y Babesia bigemina en el Centro Nacional de Sanidad Agropecuaria. De ellos, 371 provenían de trabajadores agropecuarios y 410 de donantes de la provincia de Ciego de Avila. Se partió de diluciones de 1/64, a cada seropositivo se le confeccionó una encuesta epidemiológica para conocer factores de riesgo. Se empleó la prueba de diferencia de proporciones para comparar los porcentajes de positivos. Se calcularon las medias geométricas en ambos grupos y se procedió a su comparación con la prueba U de Mann Whitney. En los trabajadores agropecuarios se detectó un 7 por ciento con anticuerpos contra el 3,9 por ciento de los donantes (p < 0,05). Se encontró mayor circulación de Babesia bovis que de Babesia bigemina
