I think I first ran across her on a thread devoted to tracking the flu. Probably swine or avian flu, those are the ones that will be the most deadly. You got the idea from her posting that she wasn’t just a casual observer.
At some point she went on to discuss Ebola. IIRC she told us that the reservoir animal was going to be fruit bats well before that fact hit the news. I’m pretty sure that she also mentioned the particular cave that the CDC had been focusing on. Convinced me that she was the real deal.
