结核病是一种严重影响人类健康的传染病。全球有近1/3人口感染了结核分枝杆菌,主要分布在发展中国家。如果不能及时和有效地控制结核病传播,在今后20年内,发展中国家将会有2亿人罹患结核病。在我国,三分之一人口已感染结核分枝杆菌,受感染人数超过4亿,其中约有10%发生结核病。 Tuberculosis is a contagious disease that seriously affects human health. Nearly one third of the world’s population is infected with Mycobacterium tuberculosis, mainly in developing countries. Without timely and effective control of the spread of tuberculosis, 200 million people in developing countries will suffer from tuberculosis in the next 20 years. In our country, one third of the population has been infected with Mycobacterium tuberculosis and infected more than 400 million people, about 10% of whom have tuberculosis.
