The competition, a qualifying event for the Tokyo 2020 Olympic Games, is scheduled for February 19 to 23 at Somerset Skatepark. 

Coronavirus, which has killed 722 people in China, has infected 33 people in Singapore so far. 

Organisers have urged National Governing Bodies and related parties to withhold making travel plans until an event update on Monday (February 10).

"Singapore, the hosting country of the upcoming Asian Street Skateboarding Continental Championship 2020, has seen an increased number of cases of the 2019 novel coronavirus in recent days," a statement on the World Skate website said.

"A number of precautionary measures have been put in place by the Singapore Ministry of health to control the spread of the virus, and the organizers of the event are continuing to maintain a high level of vigilance with regards to the situation.

"At this point we are advising NGB and related parties to withhold making travel plans until further notice. 

"In addition, there is a remaining travel restriction on people with travel history to high infection territories.

"We will update the event status on Monday of next week."

A large number of sporting events in China have been cancelled or rescheduled due to the outbreak of coronavirus. 

Sports affected include boxing, football, wrestling, basketball, tennis, hockey, badminton, diving, equestrian, golf and biathlon.

The World Athletics Indoor Championships, initially scheduled for March in Nanjing, is the most high-profile sporting event to be postponed because of the virus so far.

It has been delayed by a year until March 2021.

The opening test event for the Beijing 2022 Winter Olympics, an Alpine Skiing World Cup in Yanqing, was also cancelled.

This year's SportAccord World Sport and Business Summit in Beijing, scheduled for between April 19 and 24, is another major gathering under threat.
