The first symptom for the disease COVID-19, starts from and estimated 2 to 14 days after infection. During this time, the person is infectious and spreading the virus.

So it's possible he was already infected before March 2 (in Los Angeles), or he may have been infected as late as March 5 (in Florida).

## Behavioral Implications of Possible Exposure

Here's what I've gleaned from this article, and other information (below), as well as information on the John Cambpell videos: if I do any activity that may result in infection, I start a clock countdown of 14 days, and start wearing a mask, even at home. I have not managed to wear it all the time, but I do try to when other people are in the room. At five days, I'm at a milestone where infection is unlikely - but I must continue another 9 days before I am cleared.

Also, wipe surfaces with cleaner. Reduce contamination as much as possible. This is daily habit I am learning.

After going out shopping, all clothes go into either the hamper for wash that day or next, or straight into the washer for a hot water wash, and then a dry. The plastic hampers, when empty, are sprayed down with a cheap cleaner that contains benzalkonium chloride, a non-bleach antiviral chemical.

Shopping bags are put into the shower, and sprayed with diluted bleach, and will "take a shower with me" to be soaped and cleaned out completely, and then re-sprayed with the diluted bleach. (2 Tbsp bleach + 32 oz water.)

Otherwise, do not go out except when absolutely necessary.

Any errand that expands the scope of contact, like going to the store, should reset the countdown clock.

Other visits, to family, which do not expand the scope of contact do not reset the clock.

Scope of contact is defined as all the people within your family or household circle: it is the set of people who cannot but help contact each other frequently. Any excursion out of this circle expands the scope of contact.

A trip to the store expands the scope of contact.

A visit to the doctor expands the scope of contact.

When the scope of contact is expanded, it must be assumed that infection could have happened, and a countdown starts, and everyone must wait 14 days to verify no infection.

Things I have yet to do: develop a better way to wash and store shoes between uses, so they do not bring in germs. Maybe keep the shoes outside. Never wear shoes in the house, of course. Clean out the entryway area to be more germ resistant. Figure out a better way to clean the shopping bags.

## Update on Los Angeles County

Los Angeles County has instituted a Stay At Home policy. No non-essential shopping. No school or work, except essential jobs.
