Elon Musk says he has 'supposedly' contracted COVID-19 second time

Elon Musk said Monday that he has tested positive for COVID-19 a second time but is experiencing almost "no symptoms."

The Tesla CEO referred to COVID as the "virus of Theseus," before asking, "How many gene changes before it's not COVID-19 anymore?"

"I supposedly have it again (sigh), but almost no symptoms," he concluded in the tweet.

Musk previously tested positive for the virus in November 2020. At the time, he said he "most likely" had a moderate case of COVID, explaining that he was experiencing symptoms of a "minor cold." He said his test results were inconsistent. 

The sometimes controversial tech leader has assumed several positions on the government handling of COVID over the course of the pandemic. In May of 2020, he told Tesla employees to go back to work, despite shelter-in-place orders remaining in effect in California – where the Tesla factory was at the time. He called the continued lockdown efforts "fascist." Musk and his children are vaccinated.
