If I may add, I agree with everything Dr. Nevin just said. The analogy in the United States is Agent Orange, the defoliant that was used in Vietnam. Really, mefloquine is one of a number of toxic exposures but it's the one we're focused on today. The Agent Orange analogy was, “Oh, that was nothing, it's all in your head.” Now I see Vietnam-era patients all the time. They've been exposed to Agent Orange. It's part of what is in their disability. It's part of what the VA compensates. And I would not be at all surprised if 30 years from now, or sooner, we will see mefloquine as the Agent Orange for this generation of Somali and Afghan veterans.
