Placer County Public Health has issued a health alert after more than two dozen people from two other counties who took part in youth basketball tournaments tested positive for COVID-19.

Placer County Public Health says people who were at the center on those days may have been exposed to coronavirus and should quarantine and get tested, regardless of whether or not they have symptoms.

"The cases of COVID-19 associated with Courtside Basketball Center are a reminder that contact sports facilitate the spread of coronavirus and illustrate why tournaments are not allowed," the health alert says.
