Stay home as much as possible. If you want to go outside, keep a distance of at least a mile between you and other people. If you ever stay more than half a second closer than one mile from another person, install an antivirus on your body as quickly as possible, then bath yourself in any disinfectant (Clorox or Lysol should be preferred), for at least 48 hours.
Do not buy anything unless you are dying of starvation. If you are dying and need to buy anything, first make sure it is absolutely necessary for your survival. If so, do not go outside (because you might cross the one mile limit and not be aware of it). Instead, order a delivery of at least an thousand metric tons of whatever you need to buy, you guess it's because you need to have the least contact as possible with the outside, and the first thing you do when you even care about this is to order a delivery as less often as possible.
Once you got your delivery, do not go outside to take it until 14 days (336 hours) have passed, even if nobody's around, because it's very likely (about 1/100000000 chances) that your delivery is contaminated, and obviously it would spread to you. It is also recommended to put on a space suit before taking your precious delivery, if you have one, and to wash your delivery with vinegar during at least 48 hours, if you think your delivery won't be too much damaged.
Also, DO NOT USE RUNNING WATER, FOR ANY REASON. Running water comes from the outside, and we already stated that we want to reduce contact with the outside as much as possible. It is very likely that, one day or another, a virus will go through the aqueduct, and if everyone is using running water, there is a probability that someone will catch the disease.
If you are thirsty, instead of drinking running water (the worst thing to do), build yourself an humidity-condensing machine for which the instructions are shown here: http://letsstopcorona.org/humidity-condensing-machine
. This machine outputs pure virus-free H2O that you can drink safely.
However, use the internet carefully, because it is known that viruses can spread between computers (that's why you probably already know not to click on suspicious links), and Coronavirus might be able to adapt itself to fit the internet. There's no proof of this however.
About Food Producers:
Do not come into direct contact with your future food products, not even eye contact, because you don't want everyone who eats your products to catch the disease. Use a remote-controlled robot for virtually everything you need to do that is related to food production, and stay at least one mile away from your farm.
