To retrospectively review notified human cryptosporidiosis cases in the Waikato region of New Zealand between 2004 and 2011 and to identify risk factors for human cryptosporidiosis infection.
Waikato cryptosporidiosis notification data for the period 1 January 2004 to 31 December 2011 were analysed to identify any trends in the rates and distribution of key variables. A comparison was made between urban and rural dwelling cases.
Annual Waikato cryptosporidiosis notification rates were consistently higher than national rates. Analysis showed a seasonal peak centred around September with most cases having direct or indirect contact with cattle. Comparisons between urban and rural cases showed similar probable causes of infection and higher rates of infection in rural cases.
Those who have contact with animals continue to be at risk of infection from Cryptosporidium. The data suggests that children who live on rural properties and have contact with animal faeces, either directly or via a contaminated drinking water supply, are at the highest risk of infection.
回顾性分析2004年至2011年新西兰怀卡托地区报告的人类隐孢子虫病病例，以确定人类隐孢子虫病感染的危险因素。
分析2004年1月1日至2011年12月31日期间怀卡托地区隐孢子虫病报告数据，以确定关键变量的发病率和分布趋势。对城市和农村居住病例进行了比较。
怀卡托地区每年的隐孢子虫病报告率一直高于全国水平。分析显示季节性高峰集中在9月左右，大多数病例与牛有直接或间接接触。城市和农村病例的比较显示感染原因相似，农村病例感染率更高。
接触动物的人仍然有感染隐孢子虫的风险。数据表明，居住在农村地区、直接或通过受污染的饮用水供应接触动物粪便的儿童感染风险最高。
