Worldwide, the male to female ratio of new smear-positive tuberculosis (TB) cases is approximately two to one. However, in Pakistan, this is not the case. Rates of notified TB cases are 20-30% higher in young females compared with males, and female rates remain high regardless of increasing age. This is in stark contrast to neighboring India, which is characterized by an excess of male TB cases. It is currently unknown why rates of notified TB are so high in females in Pakistan, but it is clear that this epidemiology is a public health issue of importance that impacts transmission dynamics and disease control initiatives.
全球范围内,新的涂片阳性肺结核(TB)病例的男女性别比例约为 2:1。然而,在巴基斯坦,情况并非如此。与男性相比,年轻女性报告的 TB 病例数高出 20-30%,而且无论年龄如何增长,女性的发病率仍然居高不下。这与邻国印度形成鲜明对比,印度的特点是男性 TB 病例过多。目前尚不清楚为什么巴基斯坦女性报告的 TB 发病率如此之高,但很明显,这种流行病学是一个重要的公共卫生问题,影响着传播动态和疾病控制措施。
