Thank you, Madam Chair. There is a different definition between disease and infection. Dr. Corriveau indicated to me this is not an arbitrary, unilateral decision that we thought it would be more effective. My understanding is the current thinking in the field is a more accurate depiction of what we are dealing with is an infection as opposed to a disease, so that they are now referred to as infections as opposed to diseases. They indicate that that is the new terminology and that's what we go with.
