Formula One has become the latest sport impacted by the coronavirus pandemic with the first four races of the F1 season called off.
It comes in the wake of the decision to cancel the Australian GP after British racing team McLaren announced it was withdrawing due to a staff member testing positive for the virus.
The team member - believed to be a mechanic - was placed in quarantine in Melbourne on Wednesday after reporting symptoms related to the virus.
The decision to postpone was taken following a crisis two-hour summit involving F1 bosses, its governing body, the FIA, and a number of the sport's team principals.

The cancellation of the season-opening Australian GP follows criticism from reigning champion Lewis Hamilton over the race initially going ahead.
At a press conference in Melbourne, the six-time world champion said it was "shocking we are sitting in this room".
He added: "We are seeing (Donald) Trump shutting down the borders, the NBA has been suspended, yet F1 continues to go on."
Around 300,000 racing fans had been expected at the event over the next week.
