World Asthma Day is being observed across the country today and the theme for this year is "You can control your asthma."
According to World Health Organisation (WHO), estimates 235 million people suffer from asthma worldwide. Asthma is the most common chronic disease among children. It is not just a public health problem for high income countries: it occurs in all countries regardless of level of development.
Over 80% of asthma deaths occur in low and lower-middle income countries. Asthma is under-diagnosed and under-treated, creating a substantial burden to individuals and families and possibly restricting individuals'' activities for a lifetime. The fundamental causes of asthma are not completely understood.
