To assess the prevalence of tuberculosis (TB) in Hanoi, Vietnam, in 2003/2004.
A random selection was carried out involving 11624 subjects from 20 communes within the city.
On chest X-ray examination, 317 subjects (2.73%) showed abnormal lung opacity, of which 17 were sputum smear-positive, two concentrated smear-positive and three culture-positive, all with active TB. The prevalence of sputum smear-positive pulmonary TB was 146 per 100000 in persons aged >or=15 years (95%CI 65-228).
This is the first large-scale assessment of the prevalence of TB in Hanoi. The prevalence rate was higher than expected, suggesting that a significant number of patients with active TB, particularly females, remain undiagnosed, thus representing a continuing potential source of transmission in the community.
评估2003/2004年越南河内市结核病（TB）的患病率。
从该市20个公社随机选取11624名受试者。
胸部X线检查显示，317名受试者（2.73%）肺部有异常阴影，其中17人痰涂片阳性，2人浓缩涂片阳性，3人培养阳性，均为活动性结核病。15岁及以上人群中痰涂片阳性肺结核的患病率为每10万人146例（95%可信区间65 - 228）。
这是对河内市结核病患病率的首次大规模评估。患病率高于预期，表明大量活动性结核病患者，尤其是女性，仍未被诊断出来，因此仍是社区中持续的潜在传播源。
