Confusing personal private sector action for government is negligent. The government has done no such things in the US. Even in China, hospitals were overrun and people were most certainly told to immediately call if they had symptoms. The reason people were locked up in their homes is a simple lack of freedoms and liberties and people being conditioned to except these norms. Here in the US the government would be sued based on empirical statutes. Here in the US the government has only placed sanctions on gatherings of more than 250 people, and closed international travel. That most certainly means restaurants, etc, can run. It's at their discretion to do otherwise. Encouraging isolation so you don't get infected is entirely irrelevant to seeking medical help when infected and a serious health risk to you and others.
We've had two cases in our park alone, and supposedly the widest number of cases in the country here in WA. It's pretty close to home.
And the rampant misinformation people are consuming is no better, like media reporting on it being airborne, when it most certainly isn't, and the source of the news has big bold red disclaimers to not report on it because it's not peer reviewed or citable. Or to use masks to prevent infection (rather than to prevent spread) because SARS and influenza are ocular tropic, the best route of infection is your unprotected eyes, not your nose or mouth.
