We evaluated the frequency of typhoid fever in north Lebanon over an 8-year period (1992-1999) in patients admitted with fever to the Islami de Bienfaisance Hospital in Tripoli. We analysed 7391 serum samples for Salmonella typhi infection using the Widal and Felix tests. The cut-off value for infection was an agglutinin O titre > or = 1/160 (a value validated in an earlier study in the same region). Of the 7391 samples, 1131 (15.3%) had an agglutinin O titre > or = 1/160. The 8-year surveillance showed there was a progressive decrease in the frequency of the disease. However with over 100 cases annually, typhoid is endemic in the area and could cause major outbreaks. The monthly analysis shows that we have an increase in summer, whilst a decrease is observed in winter.
我们评估了的黎波里伊斯兰慈善医院收治的发热患者中,黎巴嫩北部地区在8年期间(1992年至1999年)伤寒热的发病频率。我们使用维达试验和费利克斯试验分析了7391份血清样本,以检测伤寒杆菌感染情况。感染的临界值是凝集素O滴度≥1/160(该值在同一地区早期研究中得到验证)。在7391份样本中,1131份(15.3%)的凝集素O滴度≥1/160。8年的监测显示,该病的发病频率呈逐渐下降趋势。然而,该地区每年有超过100例病例,伤寒在该地区呈地方病状态,可能引发重大疫情。月度分析表明,夏季病例数增加,而冬季病例数减少。
