There's biological warfare. There's not much to cover here. Basic personal hygiene and sanitation will take you further than a million doctors. Wash your hands often, don't share drinks, food, sloppy kisses, etc., with strangers. Keep your garbage can with a tight lid on it, don't have standing water (like old buckets, ditches, or kiddy pools) laying around to allow mosquitoes breeding room. This stuff is carried by vectors, that is bugs, rodents, and contaminated material.
If biological warfare is as easy as the TV makes it sound, why has Saddam Hussein spent twenty years, millions, and millions of dollars trying to get it right?
If you're clean of person and home, you eat well and are active, you're gonna live. Overall preparation for any terrorist attack is the same as you'd take for a big storm. If you want a gas mask, fine, go get one. I know this stuff and I'm not getting one and I told my Mom not to bother with one either (how's that for confidence). We have a week's worth of cash, several days worth of canned goods and plenty of soap and water. We don't leave stuff out to attract bugs or rodents so we don't have them. These weapons are made to cause panic, terror, and to demoralize. If we don't run around like sheep they won't use this stuff after they find out it's no fun. The government is going nuts over this stuff because they have to protect every inch of America. You've only gotta protect yourself, and by doing that, you help the country.
