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.
