"47 year old male who went to the Southern Maryland Hospital and died 6 hours later did die of Anthrax." So what. Stop being a panic-monger. There is no proof -- NONE AT ALL -- that the other postal worker died of anthrax.
These remain isolated incidents.
Now shut your mouth and go shopping, dammit!
You're the one who sounds panicked. Shut your own damn mouth and get out there and open your mail. Now take a deep breath. Anyway last I heard it was diagnosed as anthrax. I have driven through Clinton and it appeared pretty rural and was a ways from DC proper. So what gives?
