Among 158 adults hospitalized at the University Hospital of Libreville who did not receive any treatment against malaria before blood screening, 20 were carriers of malaria parasites. Plasmodium falciparum was seen in 19 cases with a parasitic density lower than 1,000 trophozoits/mm3 of blood in 18 cases. The most important prevalence was observed into the group of older people. In most cases symptoms related to malaria did not occur during the hospitalization. We conclude that, in such patients, a parasitic density lower than 1,000 trophozoits/mm3 is not sufficient to assess the diagnosis of malaria and does not deserve systematic treatment.
在利伯维尔大学医院住院的158名成年人中，在进行血液筛查前未接受任何疟疾治疗，其中20人携带疟原虫。19例检测到恶性疟原虫，18例的寄生虫密度低于每立方毫米血液1000个滋养体。在老年人组中观察到最高的患病率。在大多数情况下，住院期间未出现与疟疾相关的症状。我们得出结论，在此类患者中，寄生虫密度低于每立方毫米血液1000个滋养体不足以诊断疟疾，不值得进行系统性治疗。
