Control of Taenia solium taeniasis/cysticercosis: from research towards implementation.
Theoretically, considering the biology of its transmission and reservoirs, global eradication of Taenia solium taeniasis and cysticercosis is feasible. Recently much progress has been made in research on diagnosis, treatment and prevention of human taeniasis and porcine cysticercosis, although more operational research is still needed. In spite of this, global eradication of T. solium infection is still unlikely in the near future. Major obstacles to practical implementation of control measures include low levels of sanitation and health education amongst endemic populations, ineffective health services infrastructure and inadequate socioeconomic development in these areas. The continued public health impact of neurocysticercosis, especially fatalities and epilepsy, force us to identify improved options for control. In order to implement control measures in highly endemic areas the active involvement of medical services in controlling T. solium infection and more effective collaboration between medical and veterinary services is necessary. A switch is suggested from total reliance on meat inspection to active diagnosis and treatment of human taeniasis, protection of pigs against infection, promotion of health education and improved surveillance preparing chemotherapeutic and/or sanitary interventions. This could be implemented in areas where active transmission causes substantial morbidity and mortality provided there is the political will, social support, better financing and an effective organizational framework.
