its not, if you come in close contact with someone who has it;

its 10days if you are showing symptons i believe.

Hull are playing in the cup next week so how does that work

When you say "playing", do you mean they should be playing or, that they will be playing.
I would expect their game to be postponed but, we have to wait and see.

A further three Hull players now confirmed positive for Covid.

You wouldn't think that they were such a tight knit bunch that would catch it from each other with how they played last weekend.
However, on a serious note, 9 players from their squad is very significant.
The Hudds coach's comments about replicating the NRL "bubbles" seem to be about right and if SL wants to get to the end of the season, ALL clubs need to tighten their rules/protocol and try to ensure that we can get through the games that are left.
