Pierre Gasly has revealed via social media he has tested positive for Covid-19 and is self-isolating.
Gasly has become the third Formula 1 driver to test positive for coronavirus across the winter alongside Lando Norris and Charles Leclerc.
In total, six drivers have now been confirmed to have contracted the virus, with Sergio Perez, Lance Stroll and Lewis Hamilton all missing races through illness last year.
"Hello everyone, I hope you're all safe and well," wrote the Frenchman on social media.
"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.
"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."
Recently, Mercedes team principal Toto Wolff also confirmed he had completed a period of self-isolation after returning a positive test.
Pre-season testing is due to take place in Bahrain between March 12-14 with the season-opener scheduled for March 28.
