Cholera is an acute illness characterized by profuse watery diarrhea. It is caused by vibrio cholera subgroup 01 and 0139. Rapid administration of fluid replacement therapy and supportive treatment can reduce mortality to around 1%. By the close of 2011, 10,628 cases and 100 deaths were reported in Ghana with a case fatality rate of 0.99. It is important to evaluate the cholera surveillance system in Ghana to determine if it is meeting its objective.
The study was conducted in Osu Klottey district in the Accra Metropolitan area in January 2014. We assessed the operations (attributes and performance) of the surveillance system for cholera using CDC guidelines (2001). Surveillance data records at the district level from 2011-2013 were extracted and analyzed for frequency using Microsoft excel. Stakeholders and key informants were interviewed using structured questionnaire. Records were also reviewed at some health facilities and at district levels.
In 2011 and 2012, case fatality rates (1.3% and 0.65%) respectively. Males were mostly affected. The most affected age group was 20-29. In 2011, Predictive value positive was 69.2% and 50% in 2012.Cholera peaked in March 2011 and April 2012. The Government of Ghana funded the system. The system is sensitive, simple, stable, flexible, acceptable and representative. It was also useful and data quality was relatively good. Predictive Value Positive was also good.
The surveillance system is achieving its set out objectives. The system is sensitive, simple, stable, flexible, and acceptable. Predictive value positive was good.
霍乱是一种以大量水样腹泻为特征的急性疾病。它由霍乱弧菌01群和0139群引起。迅速给予液体替代疗法和支持性治疗可将死亡率降至约1%。截至2011年底，加纳报告了10628例病例和100例死亡，病死率为0.99%。评估加纳的霍乱监测系统以确定其是否实现目标很重要。
该研究于2014年1月在阿克拉大都会区的奥苏克洛蒂区进行。我们使用美国疾病控制与预防中心（CDC，2001年）的指南评估霍乱监测系统的运作（属性和绩效）。提取了2011年至2013年 district 级别的监测数据记录，并使用Microsoft excel分析其频率。使用结构化问卷对利益相关者和关键信息提供者进行了访谈。还在一些卫生设施和 district 级别审查了记录。
2011年和2012年的病死率分别为1.3%和0.65%。男性受影响最大。受影响最严重的年龄组为20 - 29岁。2011年，阳性预测值为69.2%，2012年为50%。霍乱在2011年3月和2012年4月达到高峰。加纳政府为该系统提供资金。该系统敏感、简单、稳定、灵活、可接受且具有代表性。它也很有用，数据质量相对较好。阳性预测值也不错。
监测系统正在实现其既定目标。该系统敏感、简单、稳定、灵活且可接受。阳性预测值良好。
