The Collaboration on Severe Asthma (COSA) is a global platform for the exchange of scientific and clinical information on severe asthma to better understand the complexities of the disease and continually improve strategies for optimal care of the severe asthma patient. COSA initiatives, organized by the World Allergy Organization, currently include live symposia, online learning programs, scientific journal articles and online resource sharing.

In these pages you can search a growing database of scientific article references that are related to severe asthma and link out to the abstracts and articles that are available online.

Several educational resources on severe asthma are available with the World Allergy Organization online, and you can find a searchable list here.

You can also view where the Collaboration on Severe Asthma will be presenting new information as well as past activities here.
