I'm a healthy 67 year old, but I'd still would hate to suffer through it.
I was / am fishing for how others would decide when that threshold had been crossed where they were not going out at all. We are already limiting our exposure to crowded places.
Our household doesn't have the luxury of deciding not to go out. 3 out of 4 of us still work.
DH works for a company, headquartered locally with about 550 employees. The company is owned by a billion-dollar company headquartered in Germany. DH's employer regularly brings in visitors from all over the world in the natural course of their operations. Germany, India, last week they had a man in from Hungary. So far the company has only banned travel to/from China when the news of the initial outbreak there became known. They held a regularly scheduled town hall meeting recently. DH said the coronavirus wasn't discussed at all.
Our daughter works full-time at a popular fast casual restaurant near the turnpike interchange. They have a lot of regular locals, but it's not uncommon to see out-of-state plates in the parking lot. It's been especially busy lately and her hours there have increased as a consequence. They have standard cleanliness practices, of course. She said the coronavirus hasn't been discussed at all. No special disinfecting is being done.
Our son (who has autism) works part-time in the kitchen of a nursing home. His hours vary widely from 20 to 40+ hours per week, with 4 to 11/12/13 hour shifts. He has virtually no patient contact. They had a staff meeting a few days ago on the 27th. He said the coronavirus wasn't discussed at all. You can guess how I felt on hearing the news of the outbreak in the nursing home in Washington state. How it goes there is how I expect it will go when it hits other nursing homes.
Exposure may be inevitable for our household. My efforts in stocking up are more for ensuring that we have enough in case of temporary supply chain disruptions. More to your question, another consideration is how far we go in trying to protect others under these unique circumstances. One of us being sick, especially mildly so, usually doesn't result in all of us going into self-quarantine. Like years ago, my kids didn't get to stay home from school and DH didn't get to stay home from work because
I had a cold. Unless the student/employee is sick, generally they're expected to be at school/work. Given what I said above, I'm not confident many employers have given the matter much thought.
Right now, CDC guidelines say that coronavirus testing is reserved for people without recent travel or contact if they're having difficulty breathing that requires hospitalization. People with milder cases won't know if they have it because they can't get tested. So I predict that many people with milder cases will treat it as though it is "just a cold" and others in the household will continue to go to school and work, unless those places are closed temporarily, or the school or employer instructs them to stay home if anyone in the household is sick to any degree. It's an unfortunate situation, especially because of the risk it presents to higher risk groups. Keep those things in mind when making your decisions.
