Hockey game turned into COVID-19 superspreader event

A recreational ice hockey game in Florida turned into a "superspreader" event when 14 out of 22 players developed COVID-19 after the game, including players on both teams, according to a new report.

The report, published Thursday (Oct. 15) in the Centers for Disease Control and Prevention journal Morbidity and Mortality Weekly Report, highlights the particular risk of indoor sporting events for spreading COVID-19, the authors said.

The day after the game (June 17), one of the players developed a fever, cough, sore throat and headache, and tested positive for COVID-19. In the following four days (from June 18 to June 21), an additional 13 players developed symptoms of COVID-19 — eight players were on the same team as the initial case, and five players were on the opposing team. A staff member at the rink also developed symptoms of COVID-19 in the days following the game.

The players didn't have other common exposures in the week leading up to the game, and the researchers hypothesize that one player spread COVID-19 to the other players during the game while he was presymptomatic.

The new report is one of the first to document COVID-19 spread at a sporting event or practice, although there have been a number of anecdotal reports.

"The ice rink provides a venue that is likely well suited to COVID-19 transmission as an indoor environment where deep breathing occurs, and persons are in close proximity to one another," the report said. 

The cold temperatures of the ice rink may also help the virus spread, as has been suggested by outbreaks in meat processing plants. Cold temperatures allow the virus to survive for longer outside the body, including in the air, according to Wired. And one study found that the novel coronavirus particles could travel more than 26 feet (8 meters) in the cold, stale air of a slaughterhouse, according to Bloomberg.

The ice-rink environment creates the potential for a "superspreader event, especially with ongoing community COVID-19 transmission," they concluded.
