A spin studio (aka an indoor gym with stationary bikes) in Hamilton, Ontario is dealing with an outbreak of Covid-19 stemming from one asymptomatic patron that has resulted in 69 positive cases so far, even though the studio “followed the rules”. From the CNN report:
SPINCO, in Hamilton, Ontario, just reopened in July and had all of the right protocols in place, including screening of staff and attendees, tracking all those in attendance at each class, masking before and after classes, laundering towels and cleaning the rooms within 30 minutes of a complete class, said Dr. Elizabeth Richardson, Hamilton’s medical officer of health, in a statement.
As the Washington Post reports, patrons were allowed to take their masks off while exercising:
Although Hamilton requires masks to be worn in most public settings, the law includes an exemption for anyone “actively engaged in an athletic or fitness activity.” In keeping with that policy, the studio, SPINCO, allowed riders to remove their masks once clipped into their bikes, and told them to cover up again before dismounting.
The problem here is that while the studio may have followed the rules, they were not the right rules. This outbreak appears to be another clear-cut instance of Covid-19 spread by aerosols. A group of people indoors, without masks, breathing heavily, over long periods of time in what I’m guessing is not a properly ventilated room — this is exactly the sort of thing that has been shown over and over again to be problematic.1 The science is there, but governments and public health agencies have not caught up with this yet. If you take the transmission by aerosols into account, the rules for gyms (and bars and restaurants) being open is that they should probably not be open at all — or if they are, they should be well-ventilated and the wearing of masks should be mandatory at all times.2 (via @DrEricDing)

To return once again to aerosol expert Jose-Luis Jimenez’s excellent smoke analogy, attending a spin class with an asymptomatic patron who is breathing heavily is like being in a room with someone who is furiously chain-smoking for an hour. Unless that room is extremely well-ventilated, everyone is going to be breathing in so much smoke.↩

And to compensate these businesses for their public service in remaining closed, they should be financially supported by the government. We cannot let these businesses, especially small businesses, and their owners go under, for people to lose their savings or go bankrupt, etc. as they help keep the rest of us safe. If we want to have bars and restaurants and gyms and movie theaters and concert venues on the other side of this pandemic, they have to be compensated for their sacrifice on our behalf.↩
