High risk profession - Internet companies

I did not find an official source on the CDC or Washington DC Department of Health web sites. The Washington Post has a story today which includes Internet companies in a list of high-risk professions. I do not know if there is any specific information for including Internet companies in the list. http://www.washingtonpost.com/wp-dyn/articles/A42450-2001Oct23.html "Anyone with flu-like symptoms -- an elevated white blood count, coughs, body aches, respiratory problems -- would be given antibiotics if they work in a high-risk profession or had "credible" exposure to anthrax bacteria. That includes people who work at postal facilities, general mailrooms, media organizations, government offices or Internet companies."
