My normal routine in the winter is to avoid getting a virus because it always goes into a bad case of bronchitis even from a mild cold. I have some scarring on my bronchials from gerd and from an incident at Boeing someone did something stupid and put a vat of hot chemicals under the air vent to our section of the building and when that chemical laden air hit moist tissues in the lungs it turned to acid.
So since the start of cold and flu season I have been avoiding crowds of people, doing the hand washing sanitizer routine. I don't have to change my daily routine, I am already doing the virus avoiding protocols.
If my friend gets sick he stays away and if he does need to come in I give him sanitizing wipes to use on every thing he touches that I might put my hands on. If I go shopping I do it during the hours of the day when kids are in school and people are at work. If a clerk appears to be sniffling I change to a different register or ask them to use hand santizer before they touch the items I am purchasing. Self checkout lines are a help, it avoids that chain of clerks and baggers touching my purchases after they have been touching other peoples purchases and money. You should take your own stylus to use for the payment kiosk. Avoid coffee shops, cafes, fast food drive ups etc and eat at home. Avoid public restrooms, pee before you go to the store. Use sanitizing wipes when you pump your gas if you are at a self serve. If you go to a public shower you need to take along some virus killing spray such as lysol and spray the shower first, then wait before going into it so the solution can kill the virus. But the big issue with that is the fumes so it is better to wash yourself at home. Be careful in the laundromat. Take sanitizing wipes along. If you can use hot water for washing and the hottest setting for the dryer. Oxygen bleaches, vinegar and borax washing soda additive and of course the soap will all kill the virus as will a hot dryer. But it is those tables and coin slots and surfaces and the other people around who pose the risk. So go when it is not a busy time of day. Really that is the one biggest help...do your chores at the slack time of day when there are very few other people around. Caravans do a lot of socializing and pot lucks. They do tend to pass viruses around camp. There is a big advantage to being an extrovert except when you really need some assistance from others. If you are really sick being out in the boonies alone is not to your advantage because you might need assitence with transportation to a medical facility. In that case it would be better to camp close to a town where there is a medical clinic and some type of transportation to get you there if you do begin to notice flu symptoms.
I did notice in the Seattle area that one of the coranvirus virus facilities has RVs set up to act as isolation units. Who knows but just maybe you could wrangle staying at one of them in your own RV if it came to needing to be in such a place where there is someone monitoring you.
I also in Seattle at present finishing up my build. Will I end up getting the corona virus? No way to tell that. It could happen and if it does then I will deal with it then. But as I said since September I have already been living in a style that minimizes my exposure so nothing different for me which is why I am not overly concerned other than knowing the bronchitis will be very rough on me judging from past experiences. I do end up at the emergency clinics every time I get any kind of virus for cortisone medication so I can breathe. I will talk to my doctor to get a refill of the inhaler and possibly a couple of cortisone pills to have on hand just in case. But there is a University of Washington emergency clinic in the neighborhood and they have my records on file as that is where I go when I get a virus and the subsequent lung issues. Fortunately it has been nearly two years since the last time.
