MELBOURNE (Reuters) -A team of Australian skateboarders was disqualified from an Olympic qualifying event in the United States after three positive COVID-19 tests in their group. Two skateboarders, including 13-year-old Charlotte Heath, and a coach tested positive in the United States, and others in the group were ruled out of the qualifier in Des Moines, Iowa, because they were deemed close contacts of the coach. "My understanding is the 13-year-old is very well supported by her sport and also . by her parents or a parent over there," Australia's Olympic Chef de Mission Ian Chesterman told reporters on the Gold Coast on Monday.
