The globe recorded it worst single-day of coronavirus cases, more than 100,000, since the beginning of the outbreak, the director-general of the World Health Organization said Wednesday.

The countries with the highest numbers of confirmed cases are the U.S., Russia, Brazil and the U.K., according to the WHO.

On the same day, the U.S. Centers for Disease Control and Prevention quietly published a 60-page document that recommends precautions for reopening the nation's restaurants, mass transit, schools and child care programs.

The CDC cautioned that, depending on the number of COVID-19 cases in a particular region, not all businesses and institutions should reopen just yet.

Joe Biden said Wednesday it's "totally irresponsible" for President Donald Trump to be taking and touting the anti-malaria drug hydroxychloroquine as a way to prevent COVID-19.

"There's no serious medical personnel out there saying to use that drug, it's counterproductive, it's not going to help," Biden said Tuesday in a virtual Yahoo News event with chef Jose Andres.

Here's what to know about the coronavirus, plus a timeline of the most critical moments:
