The World Health Organization (WHO) estimates the global prevalence of two of the most common chronic respiratory diseases, namely asthma and chronic obstructive pulmonary disease (COPD), to be around 335 million and 400 million patients respectively. According to the data provided by the WHO, more than 3 million people die annually from COPD. Asthma, on the other hand, is more common in pediatric population. Asthma alone results in more than 30% of pediatric hospitalizations. Moreover, it is responsible for around 180,000 annual deaths worldwide.
