AlphaTauri's Pierre Gasly said on Sunday he had tested positive for COVID-19, meaning six of Formula One's 20 race drivers have now contracted the virus.
The 24-year-old Frenchman, who recently posted pictures on Instagram of training in Dubai, made the announcement on Twitter.
"I wanted to let you know that I tested positive for COVID-19. I have told everyone I've been in contact with during these last days," he said on Twitter.
"I'm currently self-isolating and following the protocol set by the local health authorities. I'm feeling OK, and will continue to follow my training plan from home while I remain in isolation.
