He immediately went into self-isolation and was forced out of last weekend's Sakhir Grand Prix in Bahrain -- something he says was VERY tough on him.
"It's definitely been one of the hardest weeks that I’ve had for some time," Hamilton said.
Fortunately, Lewis says he's now on the mend ... and is gunning to race at the Abu Dhabi Grand Prix 2020 on Sunday.
"I just wanted to send you guys a message of positivity, let you know that I’m OK," Hamilton said. "And thank every single one of you for sending the amazing messages and videos. And I really, really appreciate it."
"I hope wherever you are, you're staying positive and fighting through whatever it is that you're facing. And I hope that I get back in the car soon. And yeah, I'm sending you guys love."
