A couple of my co-workers have been unwell, and experienced the laryngitis symptom that I've heard you and one other report. Now, perhaps they did see the Halloween show, but I do believe it's mostly just that something is going around and is rather widespread.

I have been spared so far, but considering that I'm among subway crowds, and touching subway poles and handles twice daily on weekdays, it wouldn't surprise me at all if I didn't escape entirely.
