Cluster sample technique has become a standard methodology for evaluation of immunization coverage and assessment of morbidity and mortality due to vaccine preventable and diarrhoeal diseases. The method is based on obtaining data in 30 randomly selected clusters and considered a statistically justified and economical alternative to the simple random sample approach. Cluster sample technique seems a relevant methodology for seroepidemiological studies and other surveys conducted as a part of surveillance of Rickettsial diseases.
整群抽样技术已成为评估免疫接种覆盖率以及评估疫苗可预防疾病和腹泻病所致发病率和死亡率的标准方法。该方法基于在随机选择的30个整群中获取数据，被认为是一种在统计学上合理且经济的简单随机抽样方法替代方案。整群抽样技术似乎是用于血清流行病学研究以及作为立克次体病监测一部分进行的其他调查的相关方法。
