If you suspect that you were exposed to coronavirus or have it but are suffering from the milder symptoms, you should proactively self quarantine if you live with others, and wear a mask in public to avoid infecting others.
I was a bit frustrated when I couldn't easily find an online guide to prevent the spread of coronavirus.. so I went ahead and compiled all the info I read and made this Coronavirus Prevention Guide http://stopcorona.org/
Hopefully it gets seen by enough people who will put the tips into practice and slow down the spread of the virus.
