哮喘是呼吸道常见病,也是多发病。目前全世界有近2亿患者,我国患病率接近1%,患病人数在1千万以上,其中半数在12岁以前发病。它是严重危害人们身心健康,减弱劳动能力,降低生活质量的一种疾病,而且难以得到根治。 Asthma is a common respiratory disease, but also frequently-occurring disease. There are nearly 200 million patients in the world, with a prevalence of nearly 1% in our country and more than 10 million people suffering from the disease, of which half are affected before the age of 12. It is a disease that seriously endangers people’s physical and mental health, weakens their ability to work and reduces the quality of life, and it is difficult to get radicalized.
