Do we know if the ones prescribed mefloquine right now and taking mefloquine, or who did in the recent past, had been using the other types of anti-malaria drugs and for whatever reason, as a drug of last resort, for example, are now using mefloquine because of the side effects of those other types? Do we know how many used different drugs before using mefloquine, of the ones who are using it now?
