He's just framing the question.  The answer will be available in a few weeks.

Nope, even before Hanson started circulating his explanation for the medical study with which he had no affiliation, there was already very strong evidence his “theory” was false:

Think you got the coronavirus last winter? Stanford doctors say it's unlikely

However, a study conducted by Dr. Benjamin Pinksy, the associate professor of pathology and infectious diseases at Stanford University and medical director of Stanford’s Clinical Virology Laboratory, found that at this point in time, spread of the coronavirus was actually not yet significant.

Pinsky and his team collected samples from the backs of throats or lung airways from 2,888 patients between Jan. 1 and Feb. 26 who had tested negative for other common respiratory viruses. Then, researchers combined those samples into groups of nine or 10. From there, they pooled those 292 samples for SARS-CoV-2, or COVID-19. Just two tested positive, and further testing of those two revealed only two total out of the 2,888 were infected with COVID-19.


“I was a little surprised the prevalence was so low, but it was consistent with what our public health officials in California were observing through normal surveillance methods,” Pinsky said. “Our positives came about the same time that they were identifying an uptick in COVID-19 diagnoses.”

The result, Pinksy said, suggested that Stanford “was not experiencing significant circulation of the virus among our patients presenting for care with upper respiratory symptoms prior to the third week in February.”
