BRUSSELS -- After the team of Tour de France champion Egan Bernal withdrew from all races over the next three weeks, Astana and AG2R La Mondiale became the latest outfits to stop racing on Thursday because of the virus outbreak.

The Astana team managed by Alexandre Vinokourov said it had withdrawn from races until March 20.

“With this measurement, we have chosen to protect the health of our riders and staff and to take our responsibility for the society in not further spreading the virus,” Vinokourov said.

The French-based AG2R La Mondiale said it was withdrawing from Italian races the Tirreno-Adriatico and Milan-San Remo this month.

“I cannot risk the health and integrity of our staff when the health situation is so unstable in Italy, and many legitimate questions have been raised within the team,” general manager Vincent Lavenu said.

Team Ineos earlier said it notified cycling governing body UCI it was pulling out of all races until the Volta a Catalunya on March 23.

Ineos, the team of former Tour de France winners Chris Froome and Geraint Thomas, said it took the decision in the wake of sports director Nicolas Portal's death this week, and because of the “very uncertain situation with coronavirus.”

Portal, a former rider who turned into a team official and helped guide four-time Tour champion Froome and Bernal to victory at the race, died suddenly at his home in Andorra on Tuesday.

Ineos riders were scheduled to compete at six races before March 23, including the prestigious Strade Bianche, the week-long Paris-Nice, and the famed one-day classic Milan-San Remo. Bernal was set to defend his Paris-Nice title from March 8.

“We are taking this decision to put a temporary pause on racing today because of this unique set of circumstances we are facing,” Ineos manager Dave Brailsford said. “It is right for the team given what has happened but I also believe it is in the best interests of both cycling and the wider public.”

Race organizers ASO, who also own the Tour de France, said on Thursday they still plan to go ahead with Paris-Nice.

In a sport involving constant travelling across the world with cyclists very close to spectators on open roads, the impact of the virus outbreak has been escalating. This week, Australian outfit Mitchelton-Scott decided to withdraw from racing until March 22, and Dutch team Jumbo-Visma announced it would skip Saturday's Strade Bianche.

On Wednesday, the Ministry of Health in the United Arab Emirates announced that six more people with links to the UAE Tour that was cut short last week have been infected with the virus that started in China and has spread to 70 countries. They were all linked to two previous cases involving Italians, the ministry said.

The last two stages of the UAE Tour were cancelled on Feb. 28 after two virus cases among team staff members.

Ineos said it has a duty to preserve the health of its staff and riders “in what is a very fast moving and challenging situation. We have taken the best medical advice and recognize that these are exceptional times for everyone -- beyond just cycling.”

The UCI has so far stopped short of cancelling this month's planned events, leaving authorities in the concerned countries with the decision.

“The organizers and all members of the cycling family will be obliged to comply to any such decision,” the UCI said this week.

According to cycling website Cyclingnews, doctors from 11 cycling teams have written to race organizers ASO and RCS Sport, and the UCI, requesting the cancellation of upcoming races. The UCI did not immediately respond to a request for comment from The Associated Press.
