Acute febrile illnesses such as typhoid fever, typhus, and malaria are still major causes of hospital admission in many parts of Ethiopia. However, there are substantial gaps in the monitoring systems, which result in a lack of knowledge about the geographic distribution and role of common pathogens, particularly in rural areas. Thus, this study was aimed at assessing the seroprevalence of typhoid fever, typhus, and malaria among suspected acute febrile patients at the MTU Teaching Hospital and Mizan-Aman Health Center, Southwest region of Ethiopia.
A health facility-based cross-sectional study was carried out from July to October 2022. Blood samples were collected from a total of 384 individuals. Widal and Weilfelix direct card agglutination and tube agglutination test methods were used for the serotype () and infections. The diagnosis of malaria was made using thick and thin blood smears. Questionnaires given by interviewers were used to gather information on risk factors and other sociodemographic factors. The data was analyzed using STATA/SE 14.0.
A total of 371 patients were tested for . Typhi and infections using direct card agglutination and tube agglutination methods. Using the screening test, 20.5% (76/371) patients were reactive either for O or H antigens or both, of which 55.3% (42/76) were reactive by the titration test at the cutoff value ≥ 1:80. About 17.5% (65/371) were reactive to OX19 antigen by card agglutination test, and of which 58.5% (38/65) were reactive by the titration test at the cutoff value ≥ 1:80. The overall seroprevalence of . Typhi and infections using combined direct card and tube agglutination techniques was 11.3% (42/371) and 10.2% (38/371), respectively. Out of 384 suspected malaria patients, 43 (11.2%) were found positive either for . 27 (7.03%), or . 16 (4.2%).
In this study, typhoid fever, typhus, and malaria were found among symptomatic acute febrile patients. To increase disease awareness, it is necessary to provide sustainable health education about risk factor behaviors, disease transmission, and prevention strategies. In addition, improving laboratory diagnosis services and early treatment may also lower the likelihood of potentially fatal consequences.
伤寒、斑疹伤寒和疟疾等急性发热性疾病仍是埃塞俄比亚许多地区住院的主要原因。然而,监测系统存在重大差距,导致对常见病原体的地理分布和作用缺乏了解,尤其是在农村地区。因此,本研究旨在评估埃塞俄比亚西南部地区MTU教学医院和米赞-阿曼健康中心疑似急性发热患者中伤寒、斑疹伤寒和疟疾的血清阳性率。
2022年7月至10月进行了一项基于医疗机构的横断面研究。共采集了384人的血样。采用维达试验和外斐直接玻片凝集试验及试管凝集试验方法检测伤寒杆菌()和立克次体感染。采用厚薄血涂片法诊断疟疾。由访谈员发放问卷,收集有关危险因素和其他社会人口学因素的信息。使用STATA/SE 14.0软件对数据进行分析。
共对371例患者进行了伤寒杆菌和立克次体感染的直接玻片凝集试验和试管凝集试验检测。通过筛查试验,20.5%(76/371)的患者对O抗原或H抗原或两者均呈反应性,其中55.3%(42/76)在截断值≥1:80时通过滴定试验呈反应性。约17.5%(65/371)的患者通过玻片凝集试验对OX19抗原呈反应性,其中58.5%(38/65)在截断值≥1:80时通过滴定试验呈反应性。采用直接玻片凝集试验和试管凝集试验联合检测,伤寒杆菌和立克次体感染的总体血清阳性率分别为11.3%(42/371)和10.2%(38/371)。在384例疑似疟疾患者中,43例(11.2%)被检测出疟原虫阳性,其中间日疟原虫27例(7.03%),恶性疟原虫16例(4.2%)。
在本研究中,有症状的急性发热患者中发现了伤寒、斑疹伤寒和疟疾。为提高疾病意识,有必要提供关于危险因素行为、疾病传播和预防策略的可持续健康教育。此外,改善实验室诊断服务和早期治疗也可能降低潜在致命后果的可能性。
