Despite the strong vaccination status across the NHL, ice rinks are one of the worst environments for COVID to fester in sports, leading to higher percentages of viral loads lasting for a longer period of time, experts say.
“Ice rinks are really interesting when it comes to ventilation and air flow,” said Krystal Pollitt, an assistant professor of epidemiology at Yale University who wrote a paper last year about the effects of ice rinks on spreading COVID. “We assume just because there are these really big indoor spaces that with a lot of cool air that’s being blown through that it must have really good ventilation, and air exchange. But that’s really not the case because you have these microclimate effects within the rink area, because you have this cooling that happens at the ice and then these barricades around the ice and you have this inversion effect to air becoming stagnant and effectively create a box over the sort of the surface of the ice rink.”
