Asthma is a chronic disease of the airways. According to World Health Organization, approximate 235 million people are suffering from asthma worldwide. Some estimate that about 300 million people all around the globe currently have asthma. Among the people, most sufferers are children. Regardless of income of the country, this disease is present in all countries.
However, more than 80% of deaths from it take place in low-income or lower-middle income countries. The facts behind these deaths are the under-diagnosis and under treatment in undeveloped countries.
- In recent decades, asthma has become a common problem in both, adults and children, in the whole world. This is increased due to a raise in atopic sensitization, which is directly corresponded to asthma and other allergic disorders.
- Asthma is increasing due to adoption of western lifestyles and urbanizations. Due to this, experts expect the urban population to increase with 45% to 59% in the next two decades, which also affects the number of asthmatic patients. It is expected that in 2025, the number of asthmatic people may be increased by 100 million.
- In poor countries, many patients do not get appropriate medication for the disease. Some of them even do not have access to basic medical care. However, the distribution of resources among countries may increase better health care services in these areas of the world.
- Asthma is the sole factor in the world that causes around 1% of disability-adjusted life years (DALYs). It is similar to that of cirrhosis of liver, diabetes and schizophrenia. This reflects high severity and high prevalence of asthma in the world.
- Many developing countries have a greater extent of pollution, which is needed to address appropriately and prevent asthma and other allergic diseases that occur due to air pollution and water pollution.
- Deaths due to asthma are 0.4%, which means 1 in every 250 people die with asthma in the world. An interesting fact is that many of these deaths can be prevented with good medical services in remote areas. Most of those deaths occur due to lack of medical care during acute exacerbation of asthma in developing countries.
