Setting - a hypothetical workplace in which around two dozen adult males (mainly aged 18-30 with a few older ones) come within close contact with each other -
Event - all are tested twice a week. On one occasion, one or more test positive for covid and isolate, and then a couple more test positive afew days later. All those testing positive isolate and recover within normal timescales.
Question - having been potentially exposed to virus once and not contracted covid, are the others more or less likely to contract it in the future?
In other words, are clubs likely to experience more than one outbreak over a season, or will it generally be limited to one per club?
