Mexican soccer officials say a player has been pulled from their women's team at the Pan Am Games after contracting chickenpox.
The Mexican Football Federation says Veronica Charlyn Corral Ang started showing symptoms such as fever and lesions on July 6 and alerted sports authorities.
Tests conducted at the athletes village medical clinic in Toronto confirmed Wednesday that she had chickenpox.
The Games' organizing committee says a foreign athlete contracted the varicella virus before arriving in Canada and is being treated.
Spokesman Teddy Katz says the athlete is in "self isolation" until the contagious period ends on July 12.
He says the athlete's teammates are also being assessed but the majority have been vaccinated or have already had chickenpox and are not considered susceptible.
