I just don't think everyone is looking at this right. The threat is much greater than it looks. The 2nd guy in Fl. is sick and getting worse. The antibiotics aren't working for him. What if all 20 of people exposed at the Senate should die? What if the volume exposed through the mail is much higher than the few we know about? See my post #50
Yes, it's the tip of the iceberg, the thin edge of the wedge, as anthrax takes a while to show up, apparently. But it still is treatable if caught early enough, while our smallpox vaccine supplies are pretty low right now.
They're working at St. Louis U on diluting the existing stock (of 15 million doses), which seems to be just as effective when diluted 10 or more times, but this is a weak spot in our defense. And smallpox can be treated by giving the vaccine even if someone has had the disease for 3 or 4 days, but we just don't have enough vaccine yet.
We have plenty of doxycycline and not as much cipro to treat the anthrax, but smallpox will present a problem...at least until the supplies are built up again.
