This is from an article sent to me by a Canadian friend:
"Indoor sports: While this may be uniquely Canadian, a super spreading event occurred during a curling event in Canada. A curling event with 72 attendees became another hotspot for transmission. Curling brings contestants and teammates in close contact in a cool indoor environment, with heavy breathing for an extended period. This tournament resulted in 24 of the 72 people becoming infected.

Ice hockey involves more hard breathing, small locker rooms, and relatively small benches during games and many occasions for practice, stick times, and games. If one curling tournament could create a 1 in 3 contagion rate, what might it be for hockey players with spread to families and school mates?
