Zimbabwe targets reducing malaria incidence from 22/1000 in 2012 to 10/1000 by 2017, and malaria deaths to near zero by 2017. As the country moves forward with the malaria elimination efforts, it is crucial to monitor trends in malaria morbidity and mortality in the affected areas. In 2013, Manicaland Province contributed 51% of all malaria cases and 35% of all malaria deaths in Zimbabwe. This analysis describes the trends in malaria incidence, case fatality and malaria outpatient workload compared to the general outpatient workload.
We analyzed routinely captured malaria data in Manicaland Province for the period 2005 to 2014. Epi Info version 7 was used to calculate chi-square trends for significance and Microsoft Excel was used to generate graphs. Permission to analyze the data was sought and granted by the Provincial Medical Directorate Institutional Review Board of Manicaland and the Health Studies office.
Malaria morbidity data for the period 2005-2014 was reviewed and a total of 947,462 cases were confirmed during this period. However, malaria mortality data was only available for the period 2011-2014 and cumulatively 696 deaths were reported. Malaria incidence increased from 4.4/1,000 persons in 2005 to 116.3/1,000 persons in 2014 (p<0.001). The incidence was higher among females compared to males (p-trend<0.001) and among the above five years age group compared to the under-fives (p-trend<0.001). The proportion of all Outpatient Department attendances that were malaria cases increased 30 fold from 0.3% in 2005 to 9.1% in 2014 (p-trend<0.001). The Case Fatality Rate also increased 2-fold from 0.05 in 2011 to 0.1 in 2014 (p-trend<0.001).
Despite current malaria control strategies, the morbidity and mortality of malaria increased over the period under review. There is need for further strengthening of malaria control interventions to reduce the burden of the disease.
津巴布韦的目标是到2017年将疟疾发病率从2012年的22/1000降至10/1000，并到2017年将疟疾死亡人数降至接近零。随着该国推进疟疾消除工作，监测受影响地区疟疾发病率和死亡率的趋势至关重要。2013年，马尼卡兰省的疟疾病例占津巴布韦所有疟疾病例的51%，疟疾死亡人数占所有疟疾死亡人数的35%。本分析描述了与普通门诊工作量相比，疟疾发病率、病死率和疟疾门诊工作量的趋势。
我们分析了马尼卡兰省2005年至2014年期间常规收集的疟疾数据。使用Epi Info 7版计算卡方趋势的显著性，并使用Microsoft Excel生成图表。分析数据的许可已获得马尼卡兰省省级医疗局机构审查委员会和健康研究办公室的批准。
回顾了2005 - 2014年期间的疟疾发病数据，在此期间共确诊947,462例病例。然而，疟疾死亡数据仅可获得2011 - 2014年期间的，累计报告696例死亡。疟疾发病率从2005年的4.4/1000人增加到2014年的116.3/1000人（p<0.001）。女性的发病率高于男性（p趋势<0.001），5岁以上年龄组的发病率高于5岁以下儿童（p趋势<0.001）。所有门诊就诊中疟疾病例的比例从2005年的0.3%增加了30倍，到2014年达到9.1%（p趋势<0.001）。病死率也从2011年的0.05增加了2倍，到2014年达到0.1（p趋势<0.001）。
尽管有当前的疟疾控制策略，但在所审查期间疟疾的发病率和死亡率有所上升。需要进一步加强疟疾控制干预措施以减轻该疾病的负担。
