The United States Soccer Federation cancelled upcoming men's and women's international friendlies on Thursday over concerns of the new coronavirus.
The USSF said in a statement that all senior and youth team activities planned in March and April had been scrapped.
The US men's team was due to play the Netherlands on 26 March in Eindhoven and Wales on 30 March in Cardiff.
The women's team were due to face Australia on 10 April in Sandy, Utah, and Brazil on 14 April at San Jose, California.
US travel restrictions because of the coronavirus also prompted cancellation of two planned Mexico friendlies in the United States -- against Czech Republic in Charlotte, North Carolina, on March 26 and against Greece in Arlington, Texas on 29 March.
Soccer United Marketing and the Mexican Football Federation announced the cancellations but said a third game in the team's MEXTOUR, against Colombia in Denver on 30 May, is still expected to go ahead.
"With the health of our players, coaches, staff and fans as our main priority, US Soccer has decided it was in the best interest to cancel the majority of our upcoming domestic and international camps at all levels, including our senior Men's and Women's National Team games in March and April, due to the outbreak of Covid-19," US Soccer chief medical officer George Chiampas said.
