Ask HN: Is your company responding rationally to the Corona Virus threat?

My wife's company, based in SF, has their President based in Dallas, Texas. He's saying that he doesn't want to shut the office in SF down until there are 1,000 cases being reported in SF. I think this is a huge mistake due to the fact that many in SF must take public transportation (BART ewww), and it scares me given I'm a bit older than the rest of you. What do y'all think?
