          Abstract

          No presente artigo, os autores fazem uma revisão dos aspectos epidemiológicos da teníase e cisticercose. A cisticercose é produzida pelo desenvolvimento da forma larval da Taenia, o Cysticercus, nos tecidos, sendo transmitida pela ingestão de ovos de Taenia. A cisticercose humana e animal são consideradas um grande problema sócio-econômico em muitos países. É considerada uma zoonose endêmica, estando distribuída nos países em desenvolvimento, especialmente nas áreas rurais. A invasão da larva no sistema nervoso central em humanos constitui uma séria complicação. A cisticercose é um dos maiores problemas de saúde pública dos países em desenvolvimento e a neurocisticercose é considerada a doença parasitária mais comum do sistema nervoso humano. A conservação da carne em temperatura inferior a -15ºC durante seis dias, sua cocção adequada, além da inspeção sanitária das carnes e o diagnóstico e tratamento da teníase humana em áreas endêmicas constituem as principais medidas de controle.

          Is described a review of the epidemiological aspects of teniasis and cysticercosis. Cysticercosis is caused by the development of the larval form of Taenia, wich results in the Cysticercus in tissues, and is transmitted through ingestion of Taenia eggs. Human and animal cysticercosis are a great socioeconomic problem in many countries. It is a endemic zoonosis and is widespread in developing countries especially in rural areas. Larval invasion of the central nervous system constitutes a serious complication in humans. Cysticercosis is one of the great public health problems in developing countries and the neurocysticercosis is considered the most common parasitic disease of the human central nervous system. The freezing of meat for six days in temperatures below -15ºC, its adequate cooking, meat inspection and treatment individual patients infected with adult worms in endemic areas are the main control measures.

            Prevalence and risk factors for Taenia solium taeniasis and cysticercosis in humans and pigs in a village in Morelos, Mexico.

            In a Mexican village in which Taenia solium infection was known to be endemic, we selected a cluster sample of 368 households (21% of the total) for demographic, environmental, and diagnostic surveys, and medical histories for taeniasis and cysticercosis. Coproparasitologic studies of 1,531 participants revealed infection by Taenia sp. in four (0.3%) individuals; however, 5.8% of the respondents reported a history of having passed tapeworm proglottids in feces. Of 1,552 human serum specimens, 10.8% tested positive in the cysticercosis immunoblot assay. Seropositivity increased with age and reached a maximum in subjects ages 46-55 years. Risk factors associated with seropositivity included a history of passing tapeworm proglottids, frequent consumption of pork, and poor personal and household hygiene (P less than 0.05). A history of seizures was also significantly associated with seropositivity (P less than 0.05); approximately one-third of persons with such histories were seropositive. Of 571 pigs examined by tongue inspection, 23 (4.0%) had cysticerci; infection rates increased with the age of pigs, and were higher in pigs that habitually ran loose or were fed human feces (P less than 0.05). Goodness of fit analysis confirmed that seropositive persons (but not infected pigs) were significantly clustered within households, particularly, in households in which a member reported a history of having passed tapeworm proglottids. The results of this study have identified community behavioral and environmental practices that must be modified to prevent continued transmission of cysticercosis and taeniasis.
