On the number of 5%, on the fact that we've gone from a high percentage of people using mefloquine down to 5%, it's difficult for me to speculate as to why that has happened.
I think it is really about making sure that we're educating patients about the risks of malaria and the benefits and the potential adverse effects of the medications. I believe that all of the publicity around mefloquine is impacting people's decisions. The concern, just as we saw with people making statements about vaccines and anti-vaccine campaigns, is that there's always a risk of people interpreting information too severely, such that we cause people to make choices that aren't necessarily based on really sound science, but based more on what's going on in the discussion publicly.
