艾滋病病毒(HIV)感染是一个严重影响世界各国的公共卫生问题。截止2005年,中国存活HIV感染者约65万,且呈快速增长趋势。中国也是结核病高发的国家之一〔1〕,过去结核病疫情得到了一定程度的控制,但随着HIV感染率的上升,结核病疫情控制受到严重影响。HIV感染者易并发结核病致使结核病疫情出现回升,已引起全世界的关注〔2〕。 HIV infection is a public health problem that seriously affects all countries in the world. As of 2005, there were about 650,000 HIV-infected survivors in China, showing a rapid growth trend. China is also one of the countries with high incidence of tuberculosis [1]. In the past, tuberculosis epidemic was controlled to a certain extent. However, as the HIV infection rate increased, the control of tuberculosis epidemic was severely affected. The epidemic of tuberculosis (TB) has become more common among people living with HIV, which has caused worldwide concern [2].
