Well, anecdotally, we'll say 18,000 people. I'm just going with that number. We know it's about 20,000 or somewhere around there. It's somewhat of an arbitrary number, but let's say between 15,000 and 20,000. We estimate that up to 30% of that figure may present with permanent impairment symptoms from the drug, and they have been misdiagnosed and mistreated, so there you are. You're looking at 4,000 or 5,000 people right there. That's a huge figure.
Also, remember there are neurological symptoms, and there are psychiatric symptoms. As far as neurologically, also, there are people who are experiencing tinnitus, vertigo issues, and other encephalopathy symptoms that might be misattributed because we don't have a diagnosis for mefloquine toxicity.
It's a huge number, probably about 5,000.
