• Bill Gates says he has tested positive for COVID-19.
• He announced the result in a tweet Tuesday.

The coronavirus has caught Bill Gates.

In a Twitter thread Tuesday, the billionaire reported that he tested positive for COVID-19.

"I've tested positive for COVID. I'm experiencing mild symptoms and am following the experts' advice by isolating until I'm healthy again," he wrote.

In the thread, he added that he is "fortunate" to have been vaccinated against COVID-19 and boosted, as well as "have access to testing and great medical care."

"The Gates Foundation is coming together today for the first time in two years, and I am lucky to be on [Microsoft] Teams to see everyone and thank them for their hard work," he added in another tweet.

"The foundation meeting Bill refers to in his tweet is a pre-planned, all-employee meeting that we hold every year. Bill tested positive before the meeting and attended virtually," a representative for the Bill & Melinda Gates Foundation told Insider.

His book, "How to Prevent the Next Pandemic," came out last week, published by Penguin Random House.

"We will continue working with partners and do all we can to ensure none of us have to deal with a pandemic again," he added in a final tweet.

As of Friday, new COVID-19 cases have doubled in the last month "as Omicron subvariants have spread across the country," according to the New York Times coronavirus case tracker.

On top of that, positive results are going up in all of the states and territories except seven, the tracker added.
