Tigray, the northernmost state of Ethiopia, has a population of 3.5 million, 86% rural, and 56% living in malarious areas. In 1992 a Community-Based Malaria Control Programme was established to provide region-wide and sustained access to early diagnosis and treatment of malaria at the village level. 735 volunteer community health workers (CHWs) serve 2,327 villages with a population of 1.74 million, treating an average of 489,378 patients yearly from 1994 to 1997. Recognition of clinical malaria is similar for CHWs and health staff at clinics where there is no access to microscopy. In 1996 a pilot community-financing scheme of insecticide-treated bednets was well accepted, but re-impregnation rates fell in 1998 because of war-related social upheaval. Indicators from health institutions show a progressive increase in malaria morbidity from 1994 to 1998. Repeated mortality surveys show a 40% reduction in death rates in under-5 children from 1994 to 1996 and a 10% increase from 1996 to 1998. These trends may be related to increased malaria transmission with water resources development, increased seasonal labour migration to malarious lowlands, prolongation of the transmission season with climate changes, and increasing chloroquine resistance throughout Ethiopia. Progressive extension of CHW services to ensure better coverage of women, children, migrant workers and communities near water development projects, change to first-line treatment with sulfadoxine-pyrimethamine, extension of the impregnated bednet initiative, and development of a regional warning system for epidemics should result in a greater impact on morbidity and mortality.
提格雷是埃塞俄比亚最北部的州,人口350万,86%为农村人口,56%生活在疟疾流行地区。1992年设立了一项基于社区的疟疾控制计划,以便在全地区范围内持续在村庄一级提供疟疾的早期诊断和治疗服务。735名社区卫生志愿者为2327个村庄服务,这些村庄人口达174万,1994年至1997年期间每年平均治疗489378名患者。在无法使用显微镜的诊所,社区卫生志愿者和卫生工作人员对临床疟疾的识别情况相似。1996年,一项杀虫剂处理蚊帐社区筹资试点计划很受欢迎,但由于与战争相关的社会动荡,1998年重新浸渍率下降。卫生机构的指标显示,1994年至1998年期间疟疾发病率逐步上升。多次死亡率调查显示,1994年至1996年5岁以下儿童死亡率降低了40%,1996年至1998年上升了10%。这些趋势可能与水资源开发导致疟疾传播增加、季节性劳动力向疟疾流行的低地迁移增加、气候变化导致传播季节延长以及埃塞俄比亚各地氯喹耐药性增加有关。逐步扩大社区卫生志愿者服务,以确保更好地覆盖妇女、儿童、农民工以及靠近水资源开发项目的社区,改用磺胺多辛-乙胺嘧啶作为一线治疗药物,扩大浸渍蚊帐倡议,并建立区域疫情预警系统,应能对发病率和死亡率产生更大影响。
