Nintendo says it is working with public health authorities after one of their employees tested positive for the coronavirus.

In a statement obtained by USA TODAY, the video game giant said the employee worked at the Nintendo of America office in Redmond, Washington.

"We have determined that the individual had contact with other employees and we have notified those employees to the situation," said Nintendo in a statement Friday. "All impacted employees are now self-quarantining, whether they are experiencing symptoms or not."

Nintendo said it had previously allowed employees at their offices in California and Washington, two states hit hardest by the coronavirus outbreak, to work from home.

On Friday, President Donald Trump declared a national emergency related to the outbreak, freeing up billion of dollars to go toward aid. As of Friday, there are more than 1,600 cases of COVID-19 in the U.S., according to the Centers for Disease Control and Prevention. The death toll in the U.S. is up to 41, and surpassing 5,000 worldwide.
