Los Angeles, Mar 7 (AFP) The NBA has reportedly told teams to look into strategies on how to play games without fans in the arena amid concerns over the new coronavirus outbreak.

As fears grow over the spread of the virus, and sports leagues formulate contingency plans, the NBA on Friday sent a memo to its teams telling them to start "developing" plans on how to play games with only "essential staff" in attendance should that be deemed necessary, American sports broadcaster ESPN reported.

The NBA had sent out a previous memo to teams earlier this week, recommending players to use fist-bumps instead of high-fives with fans. It also said to avoid taking items such as pens, balls and jerseys from fans to sign.

"The health and safety of our employees, teams, players and fans is paramount," the NBA said in a statement on Monday.

"We are co-ordinating with our teams and consulting with the CDC and infectious disease specialists on the coronavirus and continue to monitor the situation closely."

The global spread of COVID-19 has wreaked havoc on the international sporting calendar with Formula One motor racing, golf and athletics among the sports cancelling or postponing events.

In Italy, the hardest-hit European country with 148 deaths from the novel coronavirus, all major sports events, including football matches, will be played behind closed doors until April 3.
