Actually the article says what I said, I subscribe to Discovery and have for many years. Quote from the article:@shortbus - actuallly plague is airborne. The concept that it is flea spread only, is an historically promoted untruth. Modern testing has shown that it is in fact airborne.

"Brooks identified a mutation that changed the bubonic plague, spread by rats, into the pneumonic plague variety, which settled in the lungs and was spread by coughing. This variant spread faster and killed within 24 hours," And in my post I said bubonic.
