To use routine surveillance data to assess the trends in malaria from 2008 to 2013.
Descriptive study of records from (1) AAH laboratory malaria records; (2) admissions to AAH for malaria; and (3) malaria treatments from outpatient records.
AAH examined 35 608 blood films and diagnosed malaria in 4443 samples comprised of 2667 Plasmodium falciparum (Pf) and 1776 Plasmodium vivax (Pv). Between 2008 and 2013 the total number of malaria cases detected annually decreased by 86.5%, Pf by 96.7% and Pv by 65.3%. The ratio of Pf to Pv reversed in 2010 from 2.06 in 2008 to 0.19 in 2013. For 2013, Pf showed a seasonal pattern with no cases diagnosed in four months. From 2008 to 2013 admissions in AAH for malaria declined by 90.8%, and malaria mortality fell from 54 per 100 000 to zero. The annual parasite index (API) for 2008 and 2013 was 195 and 24, respectively. Village API has identified a group of villages with higher malaria incidence rates.
The decline in malaria cases in the AAH catchment area has been spectacular, particularly for Pf. This was supported by three sources of hospital surveillance data (laboratory, admissions and treatment records). The decline was associated with the use of artemisinin-based combined therapy and improved vertical social capital between the AAH and the local communities. Calculating village-specific API has highlighted which villages need to be targeted by the AAH malaria control team.

利用常规监测数据评估2008年至2013年疟疾流行趋势。
对以下三方面记录进行描述性研究:(1)AAH实验室疟疾记录;(2)因疟疾入住AAH的病例;(3)门诊记录中的疟疾治疗情况。
AAH共检查了35608份血涂片,确诊疟疾4443例,其中包括2667例恶性疟原虫(Pf)和1776例间日疟原虫(Pv)。2008年至2013年,每年检测到的疟疾病例总数下降了86.5%,Pf下降了96.7%,Pv下降了65.3%。Pf与Pv的比例在2010年发生逆转,从2008年的2.06降至2013年的0.19。2013年,Pf呈现季节性模式,有四个月未诊断出病例。2008年至2013年,AAH因疟疾的住院人数下降了90.8%,疟疾死亡率从每10万人54例降至零。2008年和2013年的年度寄生虫指数(API)分别为195和24。村庄API确定了一组疟疾发病率较高的村庄。
AAH服务区域内疟疾病例的下降非常显著,尤其是Pf。这得到了医院监测数据的三个来源(实验室、住院和治疗记录)的支持。下降与基于青蒿素的联合疗法的使用以及AAH与当地社区之间纵向社会资本的改善有关。计算特定村庄的API突出了AAH疟疾控制团队需要针对哪些村庄。
