Around 200 to 250 million people are affected worldwide and nearly 250,000 people die per year from asthma. In Asia the rate of asthma is lower when compared to the United States. Asthma is more common in developed countries than developing countries.
Asthma affects people of all ages, but it most often starts during childhood. Young children who often wheeze and have respiratory infections are at highest risk of developing asthma that continues beyond 6 years of age.
Can it be prevented?
We can’t prevent asthma, however we can take steps to control the disease and prevent its symptoms. There is no cure for asthma, but once it is diagnosed, it can be managed with a proper treatment plan.
We can also avoid the triggers for an asthma attack once we have identified them. Read this to understand more http://www.patientsengage.com/conditions/asthma/causes-risk-factors
