国外的研究认为结核病的死亡率和年感染率曾以4～5％自然递降,抗结核化疗普遍开展后,年感染率亦随之以12％～13％的速率下降。据我国80年代的研究统计表明肺结核的流行呈明显下降趋势;如北京1985年后与1979相比痰菌(+)率和患病率下降达44.4％,平均年递降率为9.3％。说明抗结核化疗对结核病的疫情下降起了决定作用。但近几年来临床所见的结核病似有增加趋势,尤其是“防痨网”不够健全之地区。结核病的防治工作仍不应忽视。近十年来国内外有关抗结核病药物的临床和实验研究有较多的
Foreign studies suggest that the rate of death and annual infection of tuberculosis has declined naturally from 4% to 5%. After anti-TB chemotherapy has been generally carried out, the annual infection rate will also decline at a rate of 12% to 13%. According to the statistics of China in the 1980s, the prevalence of tuberculosis showed a marked downward trend. For instance, the prevalence of sputum (+) and the prevalence rate dropped 44.4% in Beijing compared with 1979 after 1985, with an average annual decline rate of 9.3%. This shows that anti-tuberculosis chemotherapy plays a decisive role in reducing the outbreak of tuberculosis. In recent years, however, there appears to be an increasing trend of clinically seen tuberculosis, especially in areas where “anti-tuberculosis net” is not sound enough. Prevention and treatment of tuberculosis should not be neglected. Nearly a decade of clinical and experimental studies on anti-tuberculosis drugs at home and abroad have more
