Difficult to tell. Asia needs hundreds more already, particularly in China. If it begins to spread here, the demand will be outrageous. As a nurse, you know that 10-12% of SARS patients require mechanical support to breath. In spite of the sorrow of this disease, wise individuals take lemons and make lemonaide. Or, like the Chinese character for crisis...must be formed by using the character for opportunity. Perhaps we understand each other better now.
