One of the single most important things we can do to slow the spread, is isolate when we're sick or in contact with someone that tests positive. If we did this one step effectively, it would reduce infection significantly. It's something done extremely well in countries like SK, Japan, China.
People who need to isolate should be sent care packages so they don't need to go out to the shop, they should update their status regularly and be given what they need to pay bills.
