Professor Aiden McCormick:

We are basing it on the opiate substitution therapy figures for where the people who are on methadone are. We reckon that is where the patients who have hepatitis C are distributed around the country. We have reasonably good data on that. We will roll that out through the big opiate substitution therapy clinics that have a pharmacy on site and then secondarily into the community pharmacies. That is how we are basing our figures for how to spread it out.
