Asthma is a chronic disease characterized by recurrent attacks of breathlessness and wheezing, and occurs in people of all ages. It is the most common chronic disease among children. It currently affects about 235 million people.
Asthma is one of the major noncommunicable diseases
Asthma is a chronic disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. Asthma can also present with chest tightness and cough.
Asthma occurs in all countries regardless of level of development
Over 80% of asthma deaths occur in low and lower-middle income countries. For effective control, it is essential to make good-quality medications affordable and available, especially for low-income families.
For some people the symptoms become worse during physical activity or at night. Failure to recognize and avoid triggers that lead to a tightened airway can be life threatening and may result in an asthma attack, respiratory distress and even death.
Failure to adhere to appropriate treatment can lead to death
Through appropriate treatment such as using inhaled corticosteroids to ease bronchial inflammation, the number of asthma exacerbation and asthma-related deaths can be reduced.
The fundamental causes of asthma are not completely understood
The strongest risk factors for developing asthma are exposure to indoor allergens such as house dust mites in bedding, carpets and stuffed furniture; pollution and pet dander; outdoor allergens such as pollens and moulds; tobacco smoke and chemical irritants in the workplace.
