慢性呼吸系统疾病（CRD）

慢性呼吸系统疾病（CRD）是气道和肺部其他结构的疾病。其中最常见的有慢性阻塞性肺疾病（COPD）、哮喘、职业性肺疾病和肺动脉高压。除了烟草烟雾，其他危险因素包括空气污染、职业化学品和粉尘，以及儿童时期频繁的下呼吸道感染。慢性呼吸窘迫综合征是不可治愈的，然而，各种形式的治疗有助于扩张主要气道和改善呼吸急促，有助于控制症状，提高患者的生活质量。世卫组织全球反慢性病联盟（GARD）的愿景是一个人人都能自由呼吸的世界，GARD特别关注低收入和中等收入国家慢性病患者的需求。

世卫组织慢性呼吸系统疾病方案的目的是支持会员国努力减少与慢性呼吸系统疾病，特别是哮喘和慢性阻塞性肺疾病有关的发病率、残疾率和过早死亡率。

症狀

慢性呼吸系统疾病是气道和肺部其他结构的慢性疾病。其中最常见的两种是哮喘和慢性阻塞性肺疾病（COPD）。

哮喘是一种慢性非传染性疾病，其特征是反复发作的呼吸困难和喘息，其严重程度和频率因人而异。症状可能会在一天或一周内发生好几次在受影响的个人，并对一些人变得更糟，在体育活动或夜间。哮喘是儿童最常见的慢性病。

慢性阻塞性肺病不是一种单一的疾病，而是一个总括性术语，用来描述导致肺部气流受限的慢性肺部疾病。慢性阻塞性肺病最常见的症状是呼吸困难，或“需要空气”，痰过多和慢性咳嗽。

慢性呼吸道疾病的危险因素包括吸烟（包括二手烟）、空气污染、过敏原和职业风险。室外空气污染和室内空气污染（通常由固体燃料烹饪引起）也是常见的原因。

Chronic Respiratory Diseases (CRDs)

Chronic respiratory diseases (CRDs) are diseases of the airways and other structures of the lung. Some of the most common are chronic obstructive pulmonary disease (COPD), asthma, occupational lung diseases and pulmonary hypertension. In addition to tobacco smoke, other risk factors include air pollution, occupational chemicals and dusts, and frequent lower respiratory infections during childhood. CRDs are not curable, however, various forms of treatment that help dilate major air passages and improve shortness of breath can help control symptoms and increase the quality of life for people with the disease. The WHO Global Alliance against CRDs (GARD) vision is a world in which all people breathe freely, GARD focuses in particular on the needs of people with CRDs in low-income and middle-income countries.

The aim of the WHO Chronic Respiratory Diseases Programme is to support Member States in their efforts to reduce the toll of morbidity, disability and premature mortality related to chronic respiratory diseases, and specifically, asthma and chronic obstructive pulmonary disease.

Symptoms

Chronic respiratory diseases are chronic diseases of the airways and other structures of the lung. Two of the most common are asthma and chronic obstructive pulmonary disease (COPD).

Asthma is a chronic, noncommunicable disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. Symptoms may occur several times in a day or week in affected individuals, and for some people become worse during physical activity or at night. Asthma is the most common chronic disease among children.

COPD is not one single disease but an umbrella term used to describe chronic lung diseases that cause limitations in lung airflow. The most common symptoms of COPD are breathlessness, or a ‘need for air’, excessive sputum production and a chronic cough.

Risk factors for chronic respiratory diseases include tobacco smoking (including second-hand smoke), air pollution, allergens and occupational risks. Outdoor air pollution and indoor air pollution (often caused by cooking with solid fuels) are also common causes.
