Depending on the size of the office, I would argue against method like quarantine in the office

Alternative: let people go & quarantine them at home.

COVID infection is not an one-off event like 10 people get infected at once. They have overlapping incubation & infection periods. Possibly people will get keep getting infected during those 48 hours, and the whole office get quarantined again and again.

edit: on another thought, I don't think my argument holds any weight given how China has been very successful at this.
