It looks like there are some old Reddit and Quora threads where people discuss this. Some answers there seem to be * no because of non-human animal hosts for some viruses * no because everyone would die if everyone actually stayed home for 2 weeks * no because some people might be long-term carriers of some viral strains (maybe because of compromised immune systems?) * no because people's homes aren't properly isolated from one another (e.g. within an apartment building) * no because a virus could slowly spread between unlucky members of a single household and thereby persist within the household for many weeks at a time
