Armonización de la vigilancia sanitaria interfronteriza: una propuesta vinculante en salud internacional / An international health proposal to harmonize crossborder health surveillance

Estudio cuantitativo y cualitativo dirigido a identificar mecanismos y acciones que contribuyan a armonizar la vigilancia de la salud interfronteriza para dar respuestas oportunas y efectivas a eventos que puedan amenazar la seguridad sanitaria internacional. Se analizaron las capacidades de Brasil, Colombia y Perú en tres áreas: a) marco legal y administrativo; b) capacidad para detectar, evaluar y notificar situaciones de riesgo y c) capacidad para investigar, intervenir y comunicar situaciones de riesgo sanitario internacional. La recolección de datos se hizo mediante revisión documental, talleres, trabajo grupal y entrevistas semiestructuradas a actores clave de la vigilancia sanitaria en los tres países. El promedio nacional de capacidades para el trío de países en "marco legal y administrativo" fue de 69,4 por ciento; en "capacidad para detectar, evaluar y notificar", 83,3 por ciento, y en "capacidad para investigar, intervenir y comunicar situaciones de riesgo", 78,7 por ciento. Se deben dirigir más recursos hacia acciones coordinadas entre los tres países para fortalecer la vigilancia y el control de la salud pública en sus zonas de frontera.

A quantitative and qualitative study to identify mechanisms and actions to help harmonize cross-border health surveillance and provide a timely and effective response to events that may threaten international health security. The capacities of Brazil, Colombia, and Peru were analyzed in three areas: (a) the legal and administrative framework; (b) the ability to detect, evaluate, and report risk situations and (c) the ability to investigate, intervene in, and communicate international health risk situations. Data were collected through a document review, workshops, group work, and semistructured interviews with key individuals in health surveillance in the three countries. The average national capacity for the trio of countries within "the legal and administrative framework" was 69.4 percent; 83.3 percent in "the ability to detect, evaluate and report"; and 78.7 percent in "the ability to investigate, intervene in, and communicate international health risk situations." More resources should be directed toward coordinated action among the three countries in order to strengthen surveillance and public health monitoring in their border areas.

Study of simplified measures for malaria surveillance in the late consolidation phase in China.

This paper presents the results of a study on simplified surveillance methods conducted in 23 pilot counties in 11 provinces and municipalities in China where reside 15 million people and malaria control has been in the late consolidation phase. Two simplified surveillance Schemes (A and B) taking treatment of clinical cases as the main measure were implemented in 1992-1994. The rate of annual blood examination for case detection was 1.0% in pilot Scheme A, while in areas of scheme B it was 0.3%. The implementation of both Scheme A and Scheme B, simplified or without treatment of infection foci and management of mobile populations, acquired satisfactory effects against malaria. Consequently, malaria incidence was declining steadily, only a few indigenous and introduced cases were detected. The parasite rate in residents and the IFA positive rate in children were very low. The results of pilot studies and cost-effectiveness analysis indicated that Scheme B is effective, rational and economic, and can be implemented to replace the routine surveillance measures in areas where malaria has been at the late consolidation phase in China.
