Billionaire investor Warren Buffett’s daughter has reportedly quarantined herself after being exposed to the coronavirus.

Susie Buffett, 66, started a two-week self-quarantine Saturday at her home in Omaha, Nebraska, after dining with a man who later tested positive for the virus, according to the Omaha World-Herald.

The man, a senior minister at Omaha’s Countryside Community Church, sat next to Buffett at a Tuesday night event after returning from a trip to Spain, the newspaper reported Sunday. He reportedly came down with a cough and tested positive for the coronavirus Friday night.

But Buffett told the World-Herald she feels normal so far and plans to spend the time quilting, reading and working with her charity. She reportedly has not been around her 89-year-old father, indicating the Berkshire Hathaway chairman has not been exposed to the virus.

“I am not the least bit worried,” Susie Buffett told the World-Herald. “I think the more we talk about it, the better it is.”

Fears about the coronavirus led Warren Buffett to shut shareholders out of Berkshire Hathaway’s May 2 annual meeting in Omaha, a massive event known as “Woodstock for capitalists” that draws thousands of people each year.

The meeting is among several major events to be affected by the coronavirus pandemic, which has infected more than 3,700 people in the US, according to Johns Hopkins University data. Others include the South by Southwest festival in Austin and the Electronic Entertainment Expo, a video game industry convention, both of which have been canceled.
