Hold up jumping to conclusions folks. I know a bit about anthrax.
The bacteria can remain alive in the ground for centuries. It can also survive in the concrete of buildings. Kings Cross station in London has Anthrax bacteria deep within the walls for example.
Farm workers are most likely to come into contact with it (it is a livestock disease), and anyone who digs up the ground - archaeologists, construction workers etc. also runs a risk. Or anyone who works in a building with the bacteria in the concrete - if a wall becomes damaged there is a slight chance that spores could be released. These are the main ways of contracting pulmonary anthrax (ie. Anthrax breathed in as opposed to ingested or absorbed through the skin.)
Unfortunately pulmonary anthrax is also the most likely to be fatal - fortunately it is extremely rare. I hope the other workers in the building are being checked - they should be in isolation and be disinfected - they then have to take certain drugs at fairly high doses to kill any potential infection before the symptoms show.
Yes this is a horrible disease, but very unlikely to come from a terrorist source.
