Elon Musk says he has Covid for a second time, but he is feeling relatively well.

In a tweet early Monday, the CEO of Tesla and SpaceX said he "supposedly have it again (sigh), but almost no symptoms."

He previously tested positive for Covid in November 2020, before a vaccine was available, leading him to quarantine during a launch of four astronauts to the International Space Station aboard a SpaceX rocket.

Musk has raised many questions about public health policy involving Covid since the disease was first discovered. But he has said he supports vaccination, even if he doesn't believe the shots should be mandated.

"To be clear, I do support vaccines in general & covid vaccines specifically. The science is unequivocal," he tweeted back in April of last year.
