Nobody who has visited China in the past two weeks is allowed into the British outfit's motorhome at the ongoing pre-season testing in Barcelona.

A Chinese journalist was e-mailed and told not to enter upon his arrival in Europe.

The team has also banned non-essential travel to Hong Kong, Japan, Malaysia, South Korea, Singapore, Thailand and Macau.

They will travel to the season-opening Australian Grand Prix in Melbourne on March 15 via airports in the Middle East, instead of Hong Kong as planned.

Other teams have also amended their travel arrangements, for both Australia and the inaugural Vietnamese Grand Prix in Hanoi on April 5.

The Chinese Grand Prix, which was due to take place on April 19 in Shanghai, has already been postponed due to the virus.

"Given the coronavirus outbreak and based on recent updates to UK Government and World Health Organization directives, McLaren has issued a policy setting out restrictions and conditions we believe prudent to safeguard the health and wellbeing of our people, contractors and customers and protect our operations," the team said.

"Among these measures is a precaution that anyone who has travelled from China in the last 14 days is not permitted to enter a McLaren operated building or facility for up to 14 days. 

"We continue to monitor the situation closely and will revise our policy as circumstances change."

There are now more than 75,000 confirmed cases of coronavirus since it originated in Chinese city Wuhan.

More than 2,100 people have died with the vast majority of patients in China.

Thirty countries and territories are now affected.

Numerous sporting events have been either cancelled or postponed due to the crisis.
