Several members of our firm attended a conference within the last two weeks where there was an executive that contracted the virus and tested positive. All of them are self-quarantined and not allowed to come into work for the next two weeks.
The problem with self-quarantine is whether they take it seriously. They need to know the consequences -- like those of a few cases I had posted earlier.
Over here, all treatments have been made free including room at the hospital. For the 1st level contacts, they are given a care-pack (food, mask, sanitisers etc) and have them set up with a food home delivery service. Like in sales, you make it as easy as possible so the buyer just needs to sign it.
However, those people at home (quarantined) will be managed by a home quarantine team. They will call the patient daily, randomly to check if they are at home, asking them for their temperatures and recording it.
