【 摘 要 】

References(25)Malaria diagnosis is a common challenge in developing countries with limited diagnostic services. Common febrile illnesses were assessed in 280 malaria-suspected patients, and each case was subjected to clinical and laboratory examinations for malaria, relapsing fever, typhoid fever, typhus, and brucellosis. Data were entered and analyzed using Epi Info version 3.1 software. Malaria accounted for 17% (CI, 12.6–21.4%) of febrile illnesses. The remaining cases were associated with typhoid fever (18.5%; CI, 13.95–23.05%), typhus (17.8%; CI, 13.32–22.28%), brucellosis (1%; CI, −0.17–2.17%), relapsing fever (2%; CI, 0.36–3.64%), and unknown causes (44%). Approximately 7% of patients had coinfections, and 2% of patients treated as monoinfections. Approximately 1.4% of the nonmalarial patients received antimalarial treatment. The sensitivity and specificity of the CareStart Pf/pan rapid diagnostic tests in comparison with those of microscopy were 100% and 91%, respectively, with positive- and negative-predictive values of 94% and 100%, respectively. Compared with microscopy, the positive-predictive value of each malaria symptom was much lower than that of the symptoms combined: fever, 17%; sweating, 30%; headache, 18%; general body ache, 22%; loss of appetite, 21%. The study findings revealed a high proportion of nonmalarial illnesses were clinically categorized as malaria. Parasite-based diagnosis is recommended for the management of malarial and nonmalarial cases.
