在疟疾流行区,疟疾病例的诊断往往仅根据临床表现,即正在发热或有发热史,而未经实验室确诊。发热是许多急性疾病的症状,因此,有许多病人特别是儿童未患疟疾却接受了抗疟治疗。本文试图确定实用的临床标准以提高疟疾诊断的准确性,了解各种症状或体征与血片镜检阳性及恶性疟原虫密度间的关系,评价几种重要的临床标准对血检阳性和恶性疟原虫血症≥10000/μl的预测值。 In malaria endemic areas, the diagnosis of malaria cases is often based on clinical manifestations, ie, a history of fever or fever without laboratory diagnosis. Fever is a symptom of many acute illnesses and as a result, many patients, especially children, receive antimalarial treatment without malaria. This article attempts to determine practical clinical criteria to improve the accuracy of malaria diagnosis, to understand the relationship between various symptoms or signs and the density of positive and falciparum Plasmodium falciparum, to evaluate several important clinical criteria for the detection of blood tests positive and falciparum malaria Protozoosis ≥ 10000 / μl predicted value.
