"This absolutely does not define me as an athlete, as a person," Zhou said. "I am more than just another positive COVID test. I am more than just another face in the crowd."
Zhou said he's done everything in his power to stay free of the virus since the start of the pandemic and has isolated himself so much in recent months that the loneliness has been crushing at times.
