Adding to the flurry of bad news on the medical front, the World Health Organization said there is evidence that the time from exposure to development of the illness may be as long as 14 days. That suggests that many more people are likely infected, that people may be infectious longer and that quarantine periods may have to be extended. It was believed that SARS was spread by droplets and could be contracted only by close proximity to an infected person sneezing or coughing. An airborne virus would be far more infectious. …

Some new words, like some new biological contagions, also exhibit community spread, releasing themselves from someone's brain as a "fiery spurt of instant poetry" (to use Anthony Burgess' evocative phrase) and gradually "infecting" other minds as they move, meme-like, through the culture. Community spread is itself an example of such a term, appearing dozens of times in the past ten days or so as the coverage (and the threat) of SARS grows.
