Judith Anne, I suggest setting up a "Biothreats" thread-to embrace naturally-occurring and deliberate events.
I'd rather not do that, for the reason that Marburg is a pretty discrete topic, with lots of information pertaining to Marburg alone, and so is the one on Avian flu.
A separate whole forum for Biothreats, with various discrete disease topics would be the only way to encompass all the various biothreats, but frankly, I don't think that's too likely to happen.
What I DO see is where you're coming from and why, but at this point, I've got all I can do to keep up.
"Biothreats" thread"
The threat matrix threads have been incorporating all bio hazard info along with chem and nuclear as it appears on the net.
