从1995年12月4日开始，在越南南部东塔省的三个农村社区（人口28，329人）进行了为期12个月的伤寒监测。伤寒病例是通过从发烧大于或等于3天的居民中采集血液进行培养而发现的。在658例血培养中，56例（8.5%）为伤寒沙门氏菌阳性，总发病率为每年每10（5）人198例。3、4月为旱季末期，为发生高峰期。5-9岁的发病率最高（531/10（5）/年），30岁以上的发病率最低（39/10（5）/年）。2-4岁儿童的发病率为358/10（5）/年。S.发热5 ~ 6天者血培养伤寒检出率最高（17.4%）。伤寒在越南是一种高度流行的疾病，是学龄前和学龄儿童的一种重要疾病。
A population-based surveillance for typhoid fever was conducted in three rural communes of Dong Thap Province in southern Vietnam (population 28,329) for a 12-month-period starting on December 4, 1995. Cases of typhoid fever were detected by obtaining blood for culture from residents with fever greater than or equal to 3 days. Among 658 blood cultures, 56 (8.5%) were positive for Salmonella typhi with an overall incidence of 198 per 10(5) population per year. The peak occurrence was at the end of the dry season in March and April. The attack rate was highest among 5-9 year-olds (531/10(5)/year), and lowest in > 30 year-olds (39/10(5)/year). The attack rate was 358/10(5)/year in 2-4 year-olds. The isolation of S. typhi from blood cultures was highest (17.4%) in patients with 5 to 6 days of fever. Typhoid fever is highly endemic in Vietnam and is a significant disease in both preschool and school-aged children.
