The Duffy blood types survey in 544 subjects coming from French speaking African countries, shows the high percentage of subjects having a Duffy a- b- blood type (94%). It ought to be emphasized that this predominantly Duffy a- b- population resides in areas in where there is according to the WHO data, a very low incidence of Plasmodium vivax invasion. Moreover, we have taken for another example North Vietnam, an area where there is a large Plasmodium vivax invasion and where we have found a small percentage of Duffy negative subjects (5.6%). In agreement with many authors reporting an association between Duffy negatively and vivax malarial refractoriness, this survey demonstrate that in French speaking African areas where there is a very low incidence of Plasmodium vivax invasion we have found, as expected, a high rate of Duffy negative subject.
对来自非洲法语国家的544名受试者进行的达菲血型调查显示，达菲a-b-血型的受试者比例很高（94%）。应该强调的是，这个以达菲a-b-为主的人群居住在根据世界卫生组织数据间日疟原虫入侵发生率非常低的地区。此外，我们再以越南北部为例，这是一个间日疟原虫入侵率很高的地区，而我们在那里发现达菲阴性受试者的比例很小（5.6%）。与许多作者报道的达菲阴性与间日疟难治性之间的关联一致，这项调查表明，在间日疟原虫入侵发生率非常低的非洲法语地区，正如预期的那样，我们发现达菲阴性受试者的比例很高。
