emergency TUEs are always granted for exacerbations of asthma:
he is asthmatic, he had a respiratory infection
a respiratory infection in asthmatics can lead to an acute exacerbation of asthma
and acute exacerbations of asthma are no joke, they can send you straight to accident and emergency if badly treated or not treated at all
therefore, athletes with an acute exacerbation of asthma have the right to an emergency TUE, in fact they even have the right to a retroactive TUE if necessary. this is clearly stated in the WADA paperwork

so i'm surprised they are making such a fuss about it
... unless this is to do with his status as an asthmatic either not being registered or not having been renewed, which is another story altogether
