Based on current cases, I don't think it is realistic to close school, work etc. But, more can be done for contain the virus. For example, anyone has temperature and coughs to stay at home? School promote washing hand? Close contact with confirmed cases to stay at home? Cancel big indoor events? Clean public area the points to be touched oftern, like door handles ?
If Government put more effort to contain, for sure, people can think of lots to do to contain, and this will save us more trouble later. At the moment,government's attitude looks like, it's impossible to contain, then let it to be.
