The Miami Heat will employ canines to sniff out the virus among fans attending games. But can dogs be trained in time to work at the Super Bowl?

Nearly 100 million people are expected to watch Super Bowl LV in Tampa, the first time the big game has been held during a pandemic (the World Series has survived two). But only 22,000 of those viewers, 7,500 of them vaccinated healthcare workers, will be in actual attendance, representing just one-third the capacity of Raymond James Stadium. Social distancing and face-coverings will be enforced. The first few rows will be kept clear as a buffer between the field and the fans. By this stage of the pandemic, everyone should be aware that, at any one time, a portion of the population is composed of asymptomatic carriers who can infect others they come into contact with. As a result, any large gathering has the potential to become a super-spreader event with wide-reaching consequences. Large-scale testing at gatherings such as sporting events is limited by the availability of trained personnel, equipment, money, and the time it takes for the results of the actual test to work.

But an unconventional solution may be in the works.
