Serology is the most sensitive test for the diagnosis of schistosomiasis and strongyloidiasis, highly prevalent diseases in Sub-Saharan Africa (SSA). The collection of dried blood spots (DBS) on filter papers enables researchers to conduct community-based studies on this matter. We investigated the seroprevalence of schistosomiasis and strongyloidiasis on DBS in SSA migrants recently arrived in Italy. Seroprevalence was 10.2% for schistosomiasis and 2.7% for strongyloidiasis. The association between symptoms and positive serology was not statistically significant. Community-based serological screening of SSA migrants by means of DBS seems feasible and accepted; screening should be conducted independently of the presence of symptoms in such population.
血清学检查是诊断非洲撒哈拉以南地区（SSA）流行的血吸虫病和类圆线虫病的最敏感的方法。滤纸采集的干血斑（DBS）使研究人员能够对这一问题进行基于社区的研究。我们调查了最近抵达意大利的 SSA 移民的 DBS 中血吸虫病和类圆线虫病的血清流行率。血吸虫病的血清流行率为 10.2%，类圆线虫病为 2.7%。症状与阳性血清学之间的关联没有统计学意义。通过 DBS 对 SSA 移民进行基于社区的血清学筛查似乎是可行且可以接受的；在这种人群中，筛查应独立于症状的存在进行。
